USB Cigarette lighter chager

I have an old usb cigarette charger - output is 5.5V 500mA. Will this be okay to use with X1 or should I buy an official one?

My 650mAmp charger does it well enough, yours will probably too.

it is the same voltage as usb port so it should work

5.5V or 5.0V?

I use the blackberry lighter charger, 5.0 v 1A
Is it OK ???
I think I got the answer http://forum.xda-developers.com/archive/index.php/t-505222.html

volts is the only thing that matters amps are drawn and a device will draw as much as it's made to be able to the more it can draw the faster it can charge
usb is spc'd to be 5volts but would think that 5.5volt would not cause problems but
once I gave my ext usb hub 12volts and it killed it and many of the devices connected to it

So, using a 5V 500mA just to keep my X1 alive while navigating should be no problem, right? I hardly believe it'll need more.

I use the car charger from my navigation pocket loox by Fujitsu Siemens.
This works great with output 5 V 1 A.
The original charger for home has only just output 5 V and 700 mA.

i never use my sony charger because its not charging properly
i always use motorola charging because its micro usb charger the same as X1. no problem so far

qi wireless charge

i have a question
i am planning to buy a wireless charge and want to know something
if i buy the wireless charge where do i must look?
input or the output for more faster charging ?
example:
Wireless charging standard: Qi standard
Power: 10W
Wireless distance: 5mm
Input: 5V 2000mA
Output: 5V 1000mA
Frequency: 100-200 kHz
Power transform efficiency:> 75%
or dou have a link for a fastercharger already?
thank you

I have a wireless charger. It doesn't charge fast at all. You need a powerful charger to power the wireless dock. That's the 2000mA you see above.
I use a turbo charger to power my wireless dock. When connected to my phone directly, Ampere reports that it will reach up to 2200mA.
My phone now is at 50% charge and in the wireless dock charging wirelessly at 570mA.
Wireless charging is trickle charging only.

I am using several cheap QI-pads from eBay (China)
Use with standard usb-chargers (different types).
Disadvantage of QI-pads is that it's critical how the phone is placed on the pad.
Extra difficult with a Nexus 6. The back isn't flat.
With plastic material of a sleeping mat l've made a 'charging bed' that fits​ my Nexus 6.

I have a wide variety of Qi chargers scattered around the house, car, and office.
They all do an acceptable job of keeping my phone topped up throughout the day. None of them are even close to as fast as the QC 2.0 plug in chargers but that's not a problem for me. Because I can just set my phone down to charge anytime it is almost always fully charged.

Qi pad on my desk at work and night-stand at home. Phone is on it about 6-8 hours at night, and another 2-4 hours during the day. If my phone is below 50%, it will take a few hours to get back to 100%. But it is a great way to start the day at 100% charge without stress on teh USB port.

Wireless charging speed

Could anyone tell me if I'm charging wirelessly at 5W or 15W?
On one hand the notification says 'Fast wireless charging' which I've read generally means 15W.
On the other, my charger, despite being marketed as having fast wireless charging, is only certified for 'Basic Power Profile (5 Watt)'.
(I am using the 2A wall charger included with the phone.)

Install galaxy charge current, that will give you the actual charge in mAh, so you can compare the performance in different charging scenarios you may have

USB Power Delivery Cable

Looking at this article it seems like an upgraded cable could charge a device faster. If the phone shows "Fast charging" can that be improved upon? Could a USB PD cable charge faster? Is the cable that came with the phone the best?

It is true that the cable intervenes with the charge the battery receives, but, in the end, there is a limit in the charge the charger itself can supply

I have used a couple of different USB Type-C cables that are said to be suppose to offer much faster charging speeds than the bundled stock Samsung Type-C cable. Honestly I don't notice a difference in charging speeds.

The real proof is always testing with a USB wattmeter and a phone that has less than 80% charge (screen-off).
The most I get out of a stock charging brick and a Anker Type-C cable is 18 Watts. Stock cable gives me 16 Watts under the above conditions

Question Combining Fast Charging and USB C Hub -- What charge do you get

So there are two interesting threads going on... One about USB C Hubs and one about how the Tab S8 Series Super Fast Charge protocol works in real life. I'd like to see what people say about power pass-through with their USB C hubs. What it comes down to is that the Tab S8/plus/ultra really wants 10V @ 4.5V, but most chargers max out at 9V @ 3A or if they support PPS, 10V @ 3A. For hubs, I don't know what "PD Pass-Through" means or how it works and if it supports the PPS format Samsung wants. Many hubs say "support 100W 3.0 PD Pass-Through". What does this mean?
My UGREEN 70411 hub says it supports 100W PD 3.0 pass-through charging. But when I use the same cables and power supply, the charge going to the tablet battery drops precipitously with the hub in the chain:
65W PD 3.0/PPS power supply --> Tablet gives Super Fast Charge 2.0 with Ampere reporting 7A @ 4.12V charging the battery i.e. 30W
65W PD 3.0/PPS power supply --> 100W USB C Hub --> Tablet gives Fast Charging (not Super Fast Charging) with Ampere reporting 2A @ 4.12V charging the battery i.e. 8W
So it isn't even close to "passing through" the power.
Does anyone get better results? Do we need anything special in a hub to "pass through" the PPS protocol Samsung actually requires? Do I just have an old hub that doesn't support PPS?
Thanks,
Joe

I have the same issue. Using a brand new Anker USB C hub. No matter which high quality cables or 100w chargers I use, or mix of peripherals plugged into the hub (I use a 4k monitor and an SSD), the tablet doesn't charge. When the tablet is plugged in, and the cover is closed or screen is off, it charges as it should. Would really like an answer as to why this is, or a workaround. I'm trying to justify this as a laptop replacement, and inability to charge whilst simultaneusly in use and 'docked' is a potential dealbreaker.
