Portable power packs (on the go chargers) solar+USB

I often spend time away from mains power or places where i will be able to safely leave a phone ( or other gadget) plugged into the mains on charge un attended.
At the moment i hav been using a power monkey explore solar charger to keep my gadgets alive, this can charge via the its solar panel, or via the mains, and then charge my gadgets up overnight ( usually ) in my tent, so my phone is/was ready to go with a full charge in the morning, and the power monkey could then go in the sun, or sit connected, and un attended on a mains supply during the day.
Ice just done an expreiment with the power monkey explore to see how it copes with the increased demands of the Motorola Defy, and i dont think it will be able to cope as the charger has virtually exhausted itself getting my Defy from 20% to 60%, and its slightly warm to the touch.
The charger battery is rated at 2200mah, and i have had the device for a few years, so that rating may be a little lower in reality.
So has anyone got any recommendations for a portable charger/solar charger that could charge the defy from 20% up to 100% for three days or more?

A 2,200mAh should do the trick on the Defy's 1,500mAh battery, otherwise the charger's battery is exhausted and needs replacement. F.e., my 1,000mAh A-solar charger adds (only) 40% max. w w w.a-solar.eu

Take a look at the JBC rugged phones and the chargers they come with. It is a usb charger with a mechanical coil. You need to wind it to charge it up. Something like that will be a long term plan that will stay with actually no replacable parts.
Something like this.

Veho Pebble: 5000mAh battery. Will charge the Defy at least twice easily. Have one myself and it's great.

Have you thought about the powergorilla or the minigorilla

The power monkey Explore test may have been a little bit short, as the unit was only charged up showing all the bars on the LCD screen, and not the green LED as well.
In the meantime ive picked up a New Trent Extreme IMP1000 with a Li-poly battery rated at 11,000Mah the unit feature a DC input jack, a power button with 3 LEDS to indicate remaining charge, and a single USB power output.
I usually plug my defy into the IMP1000 charger after a day at work, with the battery down to 40/30% let it reach 100% charge( about 1 1/2 to 2 hours) unplug it, use the DEfy in the evening then leave it hooked up overnight to the IMP1000
This will be the 3rd night that i have repeated this process with the IMP1000 and it still has 2 out of 3 LEDs left on its power gauge, phone taking charge as normal.

How about using the powerchimp but with some more powerfull AA batteries like these
http://www.picstop.co.uk/uniross-27...=google&utm_medium=base&utm_campaign=products

I tried a powerchimp, and the batteries inside that got extremly hot ( 2,500mah GP NimH) this is usually caused by a high current drain on the batteries, and it isnt good for the batteries.
As for on the go devices so far, ive got a New trent imp1000 power pack ( which im currently testing ) a power monkey explore, a 4 AA battery USB power pack (two AA batteries in series ) a 4 AA solar charger ( chameleon) that also charges via USB, as well as 5v USB power out
As for other devices that need need power, when im away from the mains, these are: a cannon camera ( with li-ion power pack ), MP3 player, Motorola Defy
As for the New trent IMP1000 charge pack its now on Day 4, its charged my DEfy from 20% 3.681v up to 100% 4.164v in 2 hours and 20 minutes, (measured using the battery status app ) Later this evening, just before i go to bed i will hook it up again for an overnight charge, the Trent IMP1000 power pack is still showing 2 out of 3 LEDs on its power gauge.

Nokia has released a bike charger. You only have to reach about 10mph in order to reach wall socket charger efficiency (1000mA).
I believe they're about to release a micro-USB version of it. However there's an android dude already converting the existing nokia charger:
http://toddlerontour.com/universal-usb-bicycle-charger-nokia-dc-14-conversion/
//Dave

I use a MiniGorilla. Has inbuilt 10000mAh battery and lasts almost 2 weeks on charging my phone regularly without requiring a charge up itself.
Regular charging = ~every 2 days
It also turns itself off once the phone is fully charged to save its own battery.

I have one of these cheap "no-name" emergency chargers than runs on 1AA battery. However I'm pleasantly surprised: it runs up to (or rather down to) 0.7-0.8V, it has reasonable efficiency (and consequently it doesn't heat up too much), might be a good option if you have to maintain some bunch of AAs already (if you have a camera with 4AAs you already need to have 8 if you want spares).
I also have 2 small solar panels but they're more of a gimmick. Sure, even the small old one will run a small radio directly but we're talking 10-20mA. The radio will otherwise run off 2AAs for countless weeks (especially if you turn it on only when listening to it), it wouldn't even make sense to run it on rechargeables.
I run the numbers based on specs on solar chargers that catch my eye occasionally and it seems that you need to charge for quite a few days from the solar panel to pay for its own size and weight; that is in ideal conditions - in reality it will be more like over 1 week, possibly more (or rather never unless we're talking some serious expedition without access to power for multiple weeks, is there even such thing nowadays?).
However this MiniGorilla looks really great. Not cheap but it will even charge notebooks (or most likely netbooks). I already marked it as a potential gift, it belongs to the category "I would never buy one but if I have it I would use it regularly" (as opposed to the category "expensive crap that ends up in the attic if I don't re-gift or ebay it quickly").

thanks for the tip you've reminded me, that i have unused branded (philips) emergency chargers - with mini usb output and recently purchased mini to micro usb cable and a bunch of old aa's
looks like it's working

Given the low cost of good quality NiMh batteries these days i don't see the problem, if you lower the life span to only 100 charges (which is highly unlikely) its still only pennys. I use a 1 hour charger for my NiMh batteries and the batteries are too hot to handle when they come off charge and i have to say i have not noticed a shorter lifespan.

Charging time

I just wanted to know how long it takes to charge Note 2. Mine is on charging the entire night yet it goes to a max of 70%. Where as with hours of charging from pc usb it charges to a 100%.

Get the Galaxy Charging Current app in the play store, then check your cables. Probably bad cable. My original samsung cable was good until a couple months ago when it suddenly went from 1600 ma to 300 ma when it was charging.

Phone modify charge speed whith different cable configuration.
Your cable or connector have a problem.

It's a very simple math. Your N2 battery 3100 mAh. If you use Samsung 2A (2000 mA) charger, it will take you 3100 mAh / 2000 mA = 1.55 h to charge your phone. This is an ideal number considering phone is off (nothing else is draining your battery in parallel). Considering some efficiency factors it will be closer to 2.5 hours since you will not be able to get ideal 2A out of charger anyway. Your charger has the converter and usb cable. If you are not using original converter but rather something you got off ebay, most likely its rated a lot lower, maybe 1A or maybe even less - your charging speed will go down. Then, if you are using cheap usb cables - those might be able to handle only 500 mA of current (typical PC/laptop usb power) - slowing down even more. Plus, when you are charging your phone and you are running some cpu intense apps in the background (like GPS still on, etc.) - you could be discharging your phone at a fast rate in parallel with charging it up.
There are a lot of factors that will be contributing to slow charging speed of your phone. Typically converter and cable are the main ones.

Vectron is quite spot on. My Note 2 charges from >5% to 100% in about 2 and a half hours with the original Samsung AC adapter and USB cable if I'm not using the phone. The charge time dramatically increases if I use a low quality aftermarket cable.

I use an old 850 mA Palm charger which has a nice, thick, low resistance cable. Average time from ~10% to 100% is 3hrs.

Check your charging current with the above app, my Note 2 comes with a 2A stock charger and with the stock usb cable I get average of 1800mAh which would charge my phone from 0% to 100% in about 1~2 hours, i have a few third party charger/cable too, I used the said tool to find out their charging quality.
Also if you got a third party charger, check its label, they usually have the average currents stated there, if you got a 300~460mah charger it will take a while to fully charge your Note 2.

Check your charger or cable it should take a maximum of 2 hours and half to fully charge the phone.

u might want to install this " GalaxyChargingCurrent_v1.1"
to measure your cable and charger whether supply 2Amp that they should,.
anything show above 1400 then u are fine,

I have an issue charging my 7105 where it will only put through between 100-400mah (according to the Galaxy Current Lite playstore app) through causing 8+ hour charges and fast battery drain, which seemed to be the case with 4 Different MicroUSB cables and 2 chargers.
I ended up fixing this with a custom kernel and rom (beanstalk) using the cable reporting 400 and the original standard charger.
With the uNEAK Engine, I ticked "Ignore 100mA Margin" and "Ignore Unstable Power", jacking up the sliders to max, and I'm now juiced up with 1800mah, charging well within 2 hours.

I'm intriuged with this "Ignore unstable power" option in my kernel as well, but it has a warning saying to try at your own risk. Do you think there are any safety issues with ignoring unstable power?

Sounds safe enough to me!

just want to share my experience : today i tried to charge my phone with LG G2 OEM charger & cable. form 10% - 100% only took amazing ~ 1 hour 20 min :good:. phone on standby, not turned off. i checked LG G2 forum on XDA about where to buy this charger, but no avail. some said they have to call LG US CS support to place order by phone. i didn't have Galaxy Charging Current apps installed when i tried LG's charger. if i can have a hold again, will update here.
here are the charger look :

[REVIEW] Tenergy and Powermod Quick Charge 2.0 Chargers

A review for the following products:
Tenergy AC Wall Fast Charger with Qualcomm® Quick Charge™ 2.0 technology

Powermod Quick Charge 2.0 Certified D/C In-Vehicle Car USB Charger
Both chargers are as fast as advertised over my stock HTC A/C charger that came with the phone and my Rockfish car charger I've been using since my HTC Vivid days.
They both came in nice retail packaging and the Powermod car charger comes with a nice (but short) USB cable. The Tenergy wall charger has an LED on it and it is blue when an non QC 2.0 device is plugged in and turns green when a QC 2.0 compliant device is plugged in. Unfortunately the car charger doesn't have this feature. It has a blue light that rings the device but only indicates that it has power. It doesn't change color when a QC 2.0 compliant device is plugged in.
I have found that both of these chargers will not charge my Asus Transformer TF201. I find this strange because I've used other USB style wall chargers with my Asus data cable (the transformer has a proprietary changing port connector) that worked just fine. Still doing research on that one but I'll not be using these to charge my tablet. I just wanted to point this out as some of these QC manufactures say they are backwards compatible with most devices. YMMV.
I've been using both for about 3 weeks and am very happy with the performance of both units.
Below is data from a series of comparison tests to show how much faster the Qualcomm QC 2.0 chargers are over stock type chargers. The data in the HTC vs. Tenergy charger is an average of 4 charges per device. The HTC vs. Tenergy temperature comparison chart is through one full charge cycle from below 20% to 100%. As you can see the QC 2.0 does charge at a higher temperature. I also took the temperature while charging on QC 2.0 with my DotView case on and at 50% the temperature on the back of the case was 91.4 F. I have taken my phone temperature after heavy gaming and the back has actually gotten hotter just playing games than at any time during the charging cycle with QC2.0. I used a IR handheld thermogun we use at work.
The Powermod and Rockfish data is from my commute to and from work that is on average 30 minutes. There are 4 charge cycles for each devise over a 30 minute period.
Conclusion:
The performance of both units is great compared to stock. Since I can already get a full day worth of battery with between 15 and 20% left after a typical day both these chargers just make life easier. If you have to go somewhere but still have 30 minutes before you leave you can "top off" your battery before leaving if you are low. Example, you realize you have less than 10% battery but have some time before you have to leave. Plug you QC 2.0 charger in and get to at least 50% in that time. I feel much better walking out the door with 50% than 10%. With the car charger you can keep your battery "topped off" between destinations. Time will tell on the longevity of the phone battery and the chargers themselves.
I hope you've found this helpful.
I recommend both of these units.:good:

Images do not work here...

OP,
Some links would be nice. I rarely ever have any issues with running out of power like you have stated. I usually charge while i'm at my desk at work all day, and when I sleep at night, and I never have had an issue with an empty battery. I'm sure some people do have trouble with that; like those who spend all day on the phone, but I'd like to see which products you are talking about, OP.
Thanks!

I'm pretty sure this and this is what OP has in mind, but I could be wrong.

Actually I'm not sure why my pictures are not showing up. I have my pictures set to public. I'll move them and try another location as soon as I get to work.
I see the pictures.........anyone else see them?

Pictures are working now. And holy cow..that's some impressive work Thanks for taking the time to test it all!

Thanks for the input.
I have the Tenergy wall charger and I have been pleased with the results. I will probably buy the same car charger you have next.

Glad everyone seeing the data now. I put this together because of all the questions on QC 2.0 that past few months.
BTW - I do crap like this all the time at work so it really wasn't that much work other than gathering the data. The charts etc took less than an hour to create after I had all the data I wanted.

Cheers mate!
Great data indeed

I bought the car charger and it is not turning green when I plug my phone into it. Do I need to do something different?

The car charger doesn't indicate if it's charging at QC 2.0 specs. Only the wall charger does that. The only way you can tell that the car charger is doing it's QC 2.0 is by the battery level or using an inline USB current meter that will show the charge rate.
Sorry for the confusion, I'll update my review.

LG G4, stock battery, quick charging 2.0 and AUKEY charger, is it a safe match?

Hi, I've recently bought a LG G4 and this certified 2.0 charger:

...it's still boxed and I've also found a thread here in XDA sayin it doesn't work on G4. For some reasons. I still haven't tested it. Yet the reviews of LG G4 owners on Amazon of this particular charger are all very positive.
ANYWAY
Prior to the LG G4 release I read a few articles that talked about a certain 3300mA battery that was Quick Charge 2.0 compatible.
This puzzles me.
THE QUESTION:
Do I need such 3300mA battery or a QuickCharge 2.0 special battery to *safely* quick charge my LG G4, or is the stock 3000mA battery ok?
(OPTIONAL QUESTIONS)
1) Is it going to damage my phone/battery in some way? Will the battery life get shorter? Will it overheat causing the phone/battery any damage?
2) How is it possible that a Qualcomm Quick Charge 2.0 certified charger does not work with the G4?
3) Could you suggest me a trusted, working charger, possibly under 15 euros?
Thanks for your time!

I think when you get people to say it doesn't work, doesn't mean it won't charge. It means that you won't get the additional benefit of quickcharge 2.0. AFAIK, the phone will still charge at higher amp (5V 1.8A), but will not charge at the QC 2.0 (9V 2A) standard.

Thanks for your answer. I still don't know what to think because LG-G4 owners' reviews on Amazon are all positive and satisfied with the increased charging speed.
What about the main question?

I use the same exact charger on my G4. It's great.
1. No damage, and your battery life won't be any shorter than regular charging. The QC is set to slow down after 60%, if I'm not mistaken.
2. Don't know who told you that it wouldn't work with the G4..
3. Who says you have to pay a lot for quality? It's a charger..

1. I heard 75% myself but either way it slows down.
2. The G4 seems to be finicky to what QC2.0 charger it wants to work with. There are reports of it not working with the aukey and reports of it working with the aukey.
3. Cheap crappy chargers can actually cause harm. If it's QC2.0 certified there's no problem.

I got [phone was off] 30% after 20 minutes
55% after 40 minutes
75% after 1 hour
then took 40 minutes for the remaining 25%, 10 minutes the last 5 percent alone.
Is QC2.0 working? I haven't ever measured normal charge percentages. It was a little bit hot in the first hour, then it cooled down.
I used the USB cable shipped with the AUKEY charger since the instructions say "please use the included cable for your non-iOS device" or something like that.
Should I keep using it or using the original G4 cable will make a difference?
Could you please suggest me a good (possibly cheap) QC2.0 certified charger from another brand that has a more... constant behaviour with the G4?
Thanks for your time

several days ago, i buy aukey multiport QC 2.0. From my experience, QC 2.0 does not give any advantage to G4, compare to original charger. It's need 102 minute from 5% to 100%. Stock charger need 105 minute from 5% to 100%. claim that's QC 2.0 will charge 60% for 30 minute, not proven using aukey. When i test using usb voltage and current tester, aukey using 9V. So i'm curious, is really G4 is qualcomm QC 2.0 compatible ? Yes, it's can use 9V for charging, but not get advantage charging 60% for 30 minute, and not much different from stock charging that only using 5V.
Something make me curious to, why other charger with more than 2A output, needed about 3hour (or more), compare to G4 stock charging (1.8A). Is this stok charging made spesial for fast charging too ? and G4 cannot get advantage from other charger, although it's have more than 2A output ?

My genuine Samsung fast adaptive charger charges my G4 about 20%+ faster. May be an Aukey problem.

I don't think aukey is the problem. It can charge at 9v, than regular 5v. But it not make it more faster than stock charger.
But for Samsung charger, yes, it can charged faster than stock charger, according to my mailing list friend. I'm not try using it yet, just order another QC 2.0 charger. LVSun 4 port charger, can be use for desktop or car charger.

I bought this one http://www.amazon.com/gp/product/B00ZZG6IKU?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00
and it does not appear to charge any faster than regular car charger i had before. Ampere+ reports 1375mA or so

I heard that LG G Flex2, G4, is compatible with the Quick Charge 2.0 tech. If the phone is compatible, it is safe to charge it with a quick charger. And my friend use the Aukey 10000mAh Portable fast charger to charge his iphone. He says the charger works well and I wanna try it.

I just bought a Tronsmart Quick Charge charger and it charged from 15% to 100% in about 1:15 hours while a Samsung 2.1A charger (the one that came with my S4) charges it in 4 hours from 10% to 100%

If it slow down it's useless, I need to charged my phone before I leave home, like I have 80% because I used it during morning, but before leave home I need 100%...

So I just charged my phone with the original charger for the first time and it is actually giving me Quick Charge 2.0 speeds. From 27% to 67% in 40 minutes which translates to 1% every minute.

AUKEY Fast Charger ... Works great
I have the Aukey Pa-T1 5 Port Qualcomm 2.0 Certified Charger. It does charge faster than stock LG Charger. Generally, it seems to charge 1% or more per minute but slows down after about 80% charged. I have been using the LG Stock 3000ma batteries with the charger. Aukey guarantees that the charger will not harm the battery or phone. There is a special circuit inside the charger to regulate proper charging. The only way this charger won't work correctly is if you have a knockoff battery or cheap cable.

I have aukey 3 port usb quick charge and it is much faster than original LG one. Almost 3 times faster!

First thing guys i did not started this with a comparission in mind, i was just troubleshoting my phone but while i was testing all the chargers i have laying the house it seemed to me like a good idea to take note and share my findings. That said lets get to the problem:
Last mont (october 2015) i bought a new battery from official LG retailer it cost me Bs 12000 (Im from venezuela, crazy high prices for us), i did this because a part of my touch screen is dead and i read in several places that replacing the battery may fix that, well it didnt but at least i have a new battery. Anyway, the thing was super expensive, i also bought a LG "Original" Charger + USB cable at Bs 3000 from at respected seller, the Nexus 4 original oem charger fall from a table and died, it wasnt broke just didnt charge anything at all, thats why i bought a new one. I didnt pay much attention to the charging time until like 2 weeks ago, i was playing in the phone with the charger plugged and the battery was slowly discharging wtf?, since then ive been trying roms and kernel settings because i was to lazy to try another chargers until today. I was thinking about ROM and/or Kernel related problem since I updated to Android M about that time (2 weeks ago). So i didnt have idea if it was rom, kernel, battery or charger what wasnt working properly.
My phone setup:
ROM: Cataclysm Oct 27 2015 + SmartRadio Fix
Kernel: Hellscore b87-M (Hellsactive governor, row scheduler, DT2W and USB Fast Charge both enabled)
Method:
I used 2 USB cables, a generic no branded and a samsung one.
In developer options i enabled Stay Awake option so the screen will never go off while the phone is plugged.
I plugged the first charger with the generic cable and let the phone charging until it showed me the stimated remaining time for full charge, then i plugged the next charger (still with generic cable) and rebooted the phone, after boot i wated until it showed me the remaining time to go with the next charger, once i tested all the chargers i replaced the generic cable for the samsung and repeated the process. So i tested the charger twice, one with each cable, and yes i got the same results every time, so iguess this android feture is actually doing his job and saying the truth.
LG Original Charger - Not really original. Lited Output: 1000mAh
Samsung original charger, i bouth this one like 2 years ago like genuine, but is not. Listed Output: 1000mAh Now blury but i remember it was that amount.
Blu Charger from a Blu Jenny TV phone i have. Made touchscreen go crazy. Listed Output: 500mAh
Orinoquia Charger. Orinoquia is a brand selled by the goverment here in Venezuela. Listed Output: 550mAh
USB Charge. Straight from the back panel of my motherboard (MSI B75MA-E33, Windows 10 Pro x64)
Nokia Original OEM Charger. This is from my mom's Nokia Lumia. Listed Output: 750mAh
The Nokia charger was the only one that was actually delivering the amount of power that it says it should deliver. From now on im gona have a hard time thinking about wich charger im gonna buy. Dont buy cheap chargers guys and only buy them from the company itselft when possible or an authorized reseller. Sorry for my english

I always used a 2A Blackberry Playbook charger for my Nexus 4. Had it for three years and when I handed it to my Dad to use three weeks ago it would still do a day and a half normal usage.
Best charger out there. Still using it with my LG G4. Charges super quick.

Your USB cable can also make a difference.

You mentioned that you played with phone while it was charging...Its possible that you had lose contact at same time and cable was not supplying enough current for battery to charge. Just go to battery stats screen and it will show charging mode. If current being supplied is around 500 mA it will shows USB. This has happened to me on various phones including the n4. I usually just turn off wifi and data connnection and turn screen off while its charging and it really charges faster. ( better option would be to turn off phone). My charger is also broken (fell from wall socket on the floor) and it takes abut 3-4 hours to charge the phone.
I have also used friend's nokia charger and they are quite good. You can continue using it.. better use a 1.5 A or 1 A charger ( stock charger output is 1.2A)

I would also point out the Blackberry charger I use has a captive cable which reduces the connection issues.

Thanks ill try to find a charger with that output that actually delivers it.

My 0,05$:
I tried out a lot of chargers for both my nexus 4 & nexus 9 (tablet) and got by far the best results with Nillkin chargers & usb cables (you can by them cheap from banggood.com). Bought 4 so far (home-office-multiple devices): Very fast charge (much faster than original chargers included with both Nexus 4 & 9), very decent build quality, useful USB cable, charger doesn't make any humming noise, etc. Can strongly recommend.

after i had lost my original n4 charger, i used a motorola charger, which delivered max ~600mA or something. then i bought sony cycle energy wall charger CP-AD2. it is very cheap yet quite powerful. i suggest using currentwidget for checking charging speed. sony charger delivers min 700mA max 816mA (i think its the limit of the n4 since sony charger can deliver up to 2A)

Thanks for the suggestion ill try that app, didnt know fo his existence jaja

The limit is 1,5 A coz the orginal charger delivers 1,2 and there is always 300-400 mah tolerance

I agree.
I'm using a Samsung USB cable with my original LG N4 charger.
It charges twice as fast compared to the original cable that came with the charger.
However, I'm pretty sure it was okay before. Maybe the LG cable is not as durable as the Samsung cable.

Okay!! Yes it is true. I myself now use only the Xiaomi Redmi 2 Prime's charger. As it charges my Nexus 4 far more faster than the real charger.
