Best Charger For N7 (or any USB device)

I've been hunting for an extra, high quality, 2A USB charger for my devices - but I didn't want to pay $25-$30 to get a Samsung or Asus 2A USB charger. And then I came across this blog entry by Ken Shirriff where he went and reviewed 12 different USB chargers including genuine and fake apple chargers + other brands.

Really good and informative post. Definitely recommend a read. For the Cole's notes version, apple makes great USB chargers ... but not the best. The best USB charger in this review actually turned out to be the USB charger that came with the ill-fated HP TouchPad. This charger has very low noise and voltage drop characteristics.
What's more, you can actually get these great HP chargers for $15 on eBay. Or via Kijiji for $15 if you're in the Toronto area.
Mine is off Kijiji and here are logged screenshots of my N7 charging from 12% to 100% with both the Asus charger that came with it and the HP Charger. The HP charger managed to take 20 minutes off my N7's charge time! :good:

I bought the HP touchpad charger for my old Xoom FE. It was a great USB charger, and came with a bunch of heads for global use. Actually seemed to do the 2A charging thing too!

I just ordered my Nexus 7 today and you saved me a bit of searching for a reasonably priced charger. Thanks!

[Q] Portable charger

I bought this portable charger
http://www.amazon.com/Portable-External-Battery-Pack-Phones/dp/B00DW09QWS
based on battery info 2300 mAh

no answer?

I used to use a Pebble smart stick http://www.amazon.co.uk/gp/aw/d/B0069Q6CGU/ref=mp_s_a_1_12?qid=1384980624&sr=8-12&pi=
I get about a full battery and a half on my HTC One. . I'd search about though as I'm sure they were £5 6 months ago.

thanks for your answer
weird thing that portable charger is 2200mAh mine is 2600mAh and doesn't work
now I'm not sure if I should order this http://www.ebay.com/itm/5600mAh-Ext..._Phone_PDA_Batteries&var=&hash=item43bb9d0f94

Maybe something to do with how many amps and volts.? I bought a standard charger from Leeds market a couple of years back which I intended to use with a HTC Desire HD, It used to start the Google maps app every time I plugged the charger in.. I assumed it was because it was 1 1/2 amps rather than 1.

GREAT DEAL on Samsung fast wireless charger

I finally pulled the trigger on one of these! I found a good deal!

Need it lower than that.

Bought this charger from Amazon last week, but unfortunately it doesn't work on my VZW S6 Edge Plus. Phone will start charging, but after 5 seconds or so, phone will display a "charging paused" message and charging will stop. Charger just continues to blink blue. This happens whether the phone is off or on, in daydream mode, and regardless of how it's positioned on the charger.
Is this charger working for owners of the VZW Note 5?

I saw that same exact behavior on my VZW Note 5 with the older Samsung Wireless Charging Pad , so I returned it, bought this newer Samsung Fast Charge Qi Wireless Charging Pad which works flawless.

That's the exact same charger I purchased and returned. Strange.

(Review) Multiple Tronsmart Wall Chargers w/ QC 2.0 and QC 3.0

A while back when I got the LG v10, Tronsmart reached out to me and asked if I’d review one of their wall chargers in exchange for an honest amazon review, I agreed, and the charger impressed me so much I bought some others, and now I have the 2 port QC 2.0, the one port QC 2.0, the one port QC 3.0, and the Titan 5 port QC 2.0.
I saw they posted a charging analysis on their site for the s7 and based on my tests, it’s pretty spot on, though I am not going to sit and watch my phone charge for an hour and a half.) One thing I can also say is that they power my aftermarket wireless charges as well, which the factory Samsung one does not.
Just figured I offer op some affordable suggestions for wall chargers even though the hype is on wireless w/ the s7. When I come home from work and need a quick boost before going out for the night, wireless isn’t fast enough.
I have the titan on my night stand and it powers my yootech wireless charger, my tablet, my bluetooth headphones, and my moto 360 sport charger,still leaving me one for toping off the s7 in a hurry. It's a beast.
Here is the Tronsmart analysis, and the pictures below will represent mine.

9h estimated charge time from 0%

I bought a used S10 5G that did not come with a charger, so I am using my Dash charger from my OnePlus 3 phone to charge it, and the estimated charge time is 9h. I am using this cable if it matters.

Edit: I confirmed the problem to be specific to my Dash charger. I tested it on a Qualcomm charger and Google Pixel charger and the charge time was reduced to 1.5 hours. Why is it slow on my Dash charger?

What kind of amps is your Dash charger outputting? For fast charging, you need quite a lot. Even my old Samsung charger with 2 amp output is about 9 hrs from 0 percent.

The charger/cable needs to fully support the fast charging protocols.
Get Samsung 25w brick/cable. Enable fast charging. Make sure the battery temp is at least 72°F at start, preferably 85F.
Fast charging will disengage if too cool or hot (approximately >100F).
