Best Charger For GNex (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.
http://goo.gl/rym3M
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 GNex charging from 12% to 100% with both the Samsung charger that came with it and the HP Charger.

FYI, I use this charger for both my GNex and my N7. I've posted OEM vs HP Charger graphs from my N7 here.

I see nothing in those graphs that makes me think one is better than the other. The lines are virtually identical, they go from 12%-100% in the same amount of time.

It doesn't buzz like the stock one and it doesn't get hot when charging the GNex at ~1A like the stock one does. As well, this charger is capable of handling tablet charging as well. Guess I should have indicated all this in my first post.

The post is rating the chargers on far more than just how quickly it charges a phone.
Just to add my two cents, anecdotally, before even seeing this post, I was going to say that the touchpad chargers have been the best I've used also. Glad i bought 4 or 5 of them for $5/each when hp went on their firesale binge.

I read that same article and bough two of them months ago for $6. They are great. They do have a slight buzz if you put your ear up to them but nothing like the samsung one. Highly recommend them.

Interesting article. Not really sure what to make of it though, beyond not buying counterfeit chargers?

I've actually got a bunch of those HP chargers for my Gnex. I got them straight from HP for $4 each last summer. Very awesome chargers.

Is it healthy to charge the battery that fast ?

Well... the battery charges at the same speed for both the stock 1A charger and the HP 2A charger. The device itself regulates how much power it will draw, and drawing 1A from a 2A charger is surely more efficient and will result in a longer lasting and better charger, as well as one that can be used for tablets and other USB devices that want to draw more than 1A. I wonder if you can take the 2A charger and put a USB Splitter or something on there and charge 2 1A devices at the same time... I'd imagine so.

I use my OEM Galaxy S4 charger. It charges all of my devices faster than any other charger I've ever tried.

[Q] Qi Charger for Moto 360 + phone

I'm curious if anyone has found a go-to charger which easily handles both their phone and the Moto 360 at the same time. I'd like to get one Qi charger big enough to handle them both by my bedside. Thanks.

Hello.
Try this http://goo.gl/UQ98b9 <-link to eBay. Its Nokia DT 901 wireless charger ( Fatboy)
Also http://goo.gl/R5FNjz

I have one of these Panasonic ones. The coil moves to find the devices on it. Will charge the phone, then the watch. It is a bit noisy though.

That looks like an unbranded powerbot. I will go ahead and add to this thread, I got a powerbot and it charges both of my devices just fine (thought not at the same time, obviously). Even the Moto 360 w/the stainless aftermarket band charges on it just fine.

That one is made by powerqi, one of the top brands for QI product, but there are many fakes on ebay, the photo's look real, but I'm not too sure if you will get the authentic one's, as the price looks too cheap.
If you want to charge two units at once, the Panasonic can charge one at a time, also there is a DoCoMo one made by sanyo, similar to the panasonic as posted in the third post.
for dual charging look for energizer, Zen, yijieneng and I think there is another one, not to sure the name I have to look for it.

My wife bought one for me. it works very well. Here I post some pics for you. If u are interested in it, Please search the item id 141606356567 on ebay for more detailed information.

I appreciate all the replies, but the point was to find one that would charge both wirelessly at the same time.

Too noisy for side of bed at night. But fine for anywhere else. I keep mine in the kitchen and just throw my phone on it whenever I walk in the house.

I bought 2 similar to this. Doesn't work with my s6 and kinda works with the 360. Only brings the 360 to about 80% then overheats it and it turns off charging. I had to get a refund from the seller.

I bought this QiFull and have been using it for the last week. It charges just as fast as the 360's charger and all the way to 100%. It charges off the 7000 mah battery making it portable. You can also charge your phone at the same time by USB cord. For $15.99 and prime shipping it's a good deal and works well.

Choetech wireless charger
My choetech wireless charger works fine with Nexus 7 tablet, but would only charge moto360 to about 75% (and makes the watch hotter than the stock charger)

Does this thing have wireless charging or not???

Like the titles says.
I keep seeing mixed answers from different review sites.

It has wireless charging capability. Which means you will be able to buy an lg circle case and you can wirelessly charge. Or no sung in a few weeks there will be a thousand knock off after market backs with it built in.
It appears likely that most or all models will not have an out of the box back where you can wirelessly charge.

So, does it work like Samsung S5/Note 4 where you need to buy the special back that will give you wireless charging? Does it have special connectors built in under the removable back?

Yep. I'm currently doing that with my S3. Though, instead of buying a whole separate back, I'm using a wireless receiver, like the one below:
http://www.amazon.com/DigiYes-Wireless-Charger-Charging-Receiver/dp/B00DYOL2RY
As for the connector thing, looks like it since here's a picture of the back of the phone without the back cover from Michael Fisher's review from Pocketnow:

Considering you can buy the circle cases for the G4, I don't see why you can't buy the lil receiver like I have with my S3. I definitely know the S4, S5, and Note 4 for sure had those receivers you could use, but I honestly wasn't aware if the manufacturers of these made them for other devices besides the ones I mentioned.

Ok, now I have to consider this phone. Thanks!
Can't live without wireless charging anymore. Airdock + 3 QI chargers at home + 1 in my office.

No prob. Glad to help.
Haha, I know the feeling. I only even bought the receiver for my S3 since the charging port is all messed up, so this pretty much is buying time before I upgrade later this summer. Not a deal breaker if a phone doesn't have it, BUT it's super convenient and in my case, saves me from having to buy more batteries that'll be useless in less than 3 months.
Speaking of wireless charging, you have any recommendations for battery packs with Qi charging built in? I've seen a few, but I don't know anyone who's actually used one. Just the usual ones you plug into the charging port.

OnePlus 7 Pro USB Cables/Chargers

Hi Folks,
Didn't see a unified thread so why not make one
Cables I've tested so far, all seem good quality, none allow Warp charge sadly :
Anker PowerLine+ USB-C to USB 3.0 cable (6ft/1.8m), High Durability, for USB Type-C Devices Including Galaxy S8/S8+/S9/S10, MacBook, iPad Pro 2018, Sony XZ, LG V20 G5 G6, HTC 10, Xiaomi 5 and More

https://www.aliexpress.com/item/33008582664.html
If anyone has found Warp charge compatible cables than aren't only 1m please let us know. Don't really want my phone sitting at the edge of my desk as the charger is plugged in on the floor and the default cable is ridiculously short, I wouldn't even care if OP had to make it stupidly thick, give us a longer cable (That's what she said)

Official OnePlus Flat Dash (Apparently have been used with Warp Charging) cables 1m/1.5m
https://www.aliexpress.com/item/33004527678.html
￡ 9.37 for 2 of them with China Post Tracked Delivery.
Just ordered 2 of the 1.5m cables so will report back on them.

You tried these on the stock Warp charger?

ali express is the place that takes a few years to ship, right? lol Cheap but long wait times. I guess that can be a fair trade off if you're not in a rush.

Got mine in 10 days via aliexpress even though it was estimated to be 25 days+

Flat dash charge cable 150cm doesn't work with warp.
When connected to phone it says "Warp Charge" but current drops to 2000ma. Changing to warp cable 100cm instantly rises current to 5000ma+

I just ordered the 6T mclaren edition 100cm one from aliexpress. description says that one supports warp but the red one does not.

These worked on all 3 of our 7 Pros. Warp charging works. Bought 2 of them.

Thats not true. I have 150cm dash cable from Ali and it triggers Warp Charge logo but ampere is 2000-3000ma.
I have MANY very high quality cables from blitwolf, anker, baseus, choetech etc. None of them works with warp charge.

Never used them as I'm in the UK so I couldn't really provide an opinion tbh. Seems like a reseller though just like the sellers on AliExpress, can't imagine it being official in any way.

Gets about 4A on Ampere. You won't get much more than that unless you have a seriously fat cable......volt drop is the issue. To get more you need a much greater surface area of cable.....

After trying many hq china cables, and 4 diferent oneplus cables from aliexpress ("genuine") I bought 150cm original cable from official reseller and now everything works. Warp charge with 5000+ma.
Those experiments are not worth the money, I've spent nearly triple value of original one.

@cd993
It will not work. On 5m cable You will drop voltage to 3,5-4v.

Accessories Wireless charger

What's the best wireless charging to go with the GP6 pro?
I want the maximum 15w speed and not fussed with Googles proprietary and expensive pixel stand 2.
From what I can tell most don't actually come with the power adapter too also that's another additional expense and would need to be 15w+ output?

You'll be stuck at 12W max. no matter what charger you get, unless it's Google 2nd gen charger.
See here: https://9to5google.com/2021/10/19/pixel-6-tidbits-plastic-top-wireless-charging/

My bad 12w max it is.
