QI Charger/Power Bank

I wanted to get QI charger w/ my Nexus and ended up getting one that included a 10,000 mAh powerbank for basically the same price.
I thought it was going to feel pretty cheap, but to my surprise it seems like its pretty good quality. For 40 bucks for both a QI and a power bank in one it's pretty kick arse! So be forewarned the "IN STOCK" status is BS it ships from China so don't expect within a week; I think I got mine in 3 weeks.
Also the instructions are horrendous, not sure who translated it but its actually comedy. I think says something like... "Use it if it bulges, smells or smokes." (instead of dont) and has FAQ's that have no questions. Literally every line in the instructions does not make sense.
So you can use this as a normal QI charger. As a powerbank you can use QI or plug it in through the USB ports (2) which makes more sense so you dont have 30% power loss as with QI. Powerbank is same shape as phone just about twice as thick and slightly larger width and length. Finished material is smooth so if you have a hard plastic case it may easily slide off or not become centered well enough to charge. I have a case no issues charging through the case. It does also get a full charge and it does not get my phone more than warm (same as wall charger).

I'd be very interested in a test to see what the actual capacity of this is. Im always wary with a no name brand battery from China because they tend to always overstate their battery capacities. Wish there were some reviews, but I might give it a go anyway to test it out myself.

Looks interesting, but the lack of reviews make it sound dubious

Its weird how almost all of the qi power banks on amazon have no reviews. Seems like something everyone should have. Ridiculously useful. I am wondering why the one posted above is a good 25% cheaper than all the others of the same 10,000 mah capacity though.
Would absolutely love for the OP to test how many full charges of the Nexus 5 he could get from the device using USB and then Wireless charging, but that would probably take a while. Also OP, when you say that the case is smooth, is it smooth like the soft touch plastic on the back of the Nexus 5 or smooth like the shiny plastic on galaxy phones?

I'm waiting for RavPower Qi Wireless Charging Pad with a built-in 4800mAh battery coming back in stock. It seems like a great fit with my Nexus 5 as I checked a review from WPCentral.

Ordered one
Just ordered one. Will let you guys know when I get it, what it's like!

no problem but may be a few days I'm getting over a day cycle on my nexus so far. I bought it mostly for the QI charger the bank was a bonus/ I will keep a log but try and get full cycles out of it to make it easier.
As far as the smoothness it is more like the shiny plastic on the galaxy phones. My phone has a plastic case it doesn't slide to much but I could see if it got bumped it would move. I had bought a screen protector someone posted that i don't like it's kind of rubbery or tacky feel i was thinking about taking it off and putting it on the charger so it was a little more "grippy".
Give me a few days I'll put up some stats for you

Oh I know, but the ones sold under the badge of Samsung or LG are usually dead on their mah capacity ratings. Not so much for random Chinese brands I havent heard of before.

Amazons having a 50% off deal on battery packs if you buy the RAVpower qi charger. I just picked up the charger and a RAV 8400mAh pack for just over 60 bucks. I've been wanting both for a while now and this deal was just to good to pass up. I do a lot of backpacking and have been debating between a battery pack vs. a solar charger for some time now as well. The pack is actually lighter than any of the solar charges I was looking at. And for 18 bucks was a no brainer.

so here are some stats on this as a power bank not sure how much power loss over a few days is normal but after a full charge of the bank using the cable here is what I came up with:
night one charger started at 51% .49 of the full 2300 mAh nexus 5 battery = 1127 mAh
night two started at 18% .82 = 1886
night three started at 22% .78 = 1794
night four started at 28% .72 = 1656
night five started at 9% died at 32% = 529
______________________________________________________________________
TOTAL mAh= 6992

Interesting. And that is using the cable and not the Qi wireless charging? Its always said that Qi will have around a 30% loss in efficiency, which would make your numbers perfectly in line with what a 10,000 mah battery should do. Of course if you were using a cable it might just be that the low cost of the device translates to a less efficient transfer of energy. Still able to get roughly 3 full charges out of the power bank is pretty awesome.

Yea thats through the cable, I know even turned off there is power loss on rechargeable batteries but I don't know what is normal power degradation equates to in a percentage. I agree though roughly 3 full charges may not be a full 10,000 mAh bank, but at the price even if it equates to a 7000 bank its not bad. Throw in the QI (which is mainly what I bought this for anyway) and this is pretty sweet deal :laugh:
I'll do it again and see what I come up with for round 2

Call me crazy but given the inefficient nature of Qi I'd at least want a larger (12000 or more) battery. I've got the anker slim 4500 and it's barely enough for 1 and a half charges (granted I use it while charging), I'd be interested how long this would last while powering the Qi electronics as well as the inefficient charging of the phone.

I wouldn't just say it's pretty good for the price. It's unbelievably low. Your average Qi charger costs $35 for really cheap models while external batteries of 8000 maH cost about $40 each.
However, I did purchase this and I will post again after I try it out and give you guys a review on it, seeing that there is only one amazon review so far.

Bump!
I have received the charger, and right off the bat I want to say something that I was extremely surprised with. Along with the cheap price, apparently the free-shipping was free 2-day shipping as well. I was rather shocked when I discovered it 2 days after I ordered it.
The device is rather portable, it is roughly twice the weight of an N5 and roughly the same dimensions. With a case on my phone ( I use a Spigen Ultra Hybrid), when I put it on it almost conforms perfectly except the charger is about a half inch longer.
The material is very glossy and easy to get fingerprints on, and looks *sort of* cheap, mainly due to the chrome rim binding it. However it feels solid pretty far, except for a power button rattle.
I have not kept track of the exact numbers, but so far this thing has satisfied me pretty well. This is my first Qi charger, so I am not aware on whether or not it's supposed to slightly warm up when charging, but it does. The charge rate is pretty decent, 1% every 2 minutes it seems like. The wired charging speeds obviously depend on whether or not you're using the 1A port or the 2.1A port, but the charging speeds for those are already cataloged so it is unnecessary for me to elaborate on it.
The LEDs are pretty bright but it is very hard to see them unless you're looking directly from above it. The battery does seem like it's 8000maH (before power effiency decreases, so the battery is actually 5600maH effectively).
I give it a 8/10 as a product. A 9/10 as a product considering the price and shipping. 100% Recommended

too bad I cant find it anymore on amazon, i was waiting for some review like this to pull the trigger and purchase it..

How is the qi charging? How many times can you charge it using this on battery and how fast does it charge on qi? If you dont mind me askin.

I picked one up and like it very much! It's a tad longer than the Nexus 5 and about the same otherwise in dimensions. It's quite heavy. The charging works well and it's not picky about positioning. Only wish for improvement is that it's a smooth metallic surface all around so it's easy for the phone to slide. I might lay down some non-grip material over it to improve that.
It's a great deal since it's as cheap or cheaper as most qi chargers and as most battery packs but you get both in one.

Sorry for the bad wording previously, but it charges at a rate of about 1% per 2 minutes. I have not the time to conduct from full experiments but it seems that I was able to get about two full phone charges more or less out of it, which is pretty appropriate.
Another note, the LEDs are so weird. They're sort of like mini flash-lights. As I said, you can't really see them unless you're viewing them head on, but last night when I was charging the battery I could use the LED lights to look around my room. This was no problem though as it did not spread, and I simply flipped the battery over .

This seems like the exact same as another one that's been making the rounds, except it's advertised as 10000 mAh. Look up TX-5600 power bank. They sell a few different colors at dx.com, but I bought mine at Amazon (another brand) http://www.amazon.com/gp/product/B00FS1NTMW/. I wonder if it's just plain old deceptive advertising, or if they just use the same shell and put another battery in.
I gotta say, I'm very happy with mine though.

i just ordered one..hoping to get it friday.
Question:
If i use it mainly as a QI charger and leave it plugged in most of the time..will it degrade the battery?
i dont have a need to carry the external battery around all the time, i just needed a 2nd QI charger and since this was a 2 in 1 for $30 i bought it.
I see that theres an on/off button. IDK if that only functions as an on/off for the battery pack itself or if it also protects the battery from overcharge when it is switched off and used just as a qi charger.
thanks in advance

I ordered one of these. Looks decent and charges devices quickly using wired mode. However, Qi charging seems inefficient. After charging up the device overnight, it was drained after a single charge of my N5. Seems to only make sense to buy this if you use a wired charging when on the go and use the qi charging when you're plugged into AC. I usually use this device while plugged into AC on my nightstand so it suits my needs. If I'm in a rush to go out and have a phone or tablet that has little charge, I'll bring this device and charge on the road using a cable.
As for the online reviews, they are likely biased. The seller offers a free gift IF you post a "positive product experience". Doesn't seem like a moral practice to me. Anyways, since the product itself works as I described I completed a positive review. Getting the free gift has been like pulling teeth. The vendor/distributor is inflexible and comes up with unwritten statements that state, "our policy is..." long story here. This makes me a bit concerned if my unit needs warranty in the future. Definitely a consideration if you decide to buy one.

Thanks for the bump. Ordered for $30. What a deal.

[BATTERY] To everyone that complain about battery life!

I read the biggest difference between the g2 and n5 are the battery life..
No biggy. I just bought one of these for £19.97 from eBay.
It's a "Power Bank" portable charger with a capacity of 15000mAh.
It has two ports, 1A and 2A. 2A is actually 2.1A, which is fairly fast. It's about 0.5 cm taller and wider than the n5, so you can just sit your phone comfortably on top of it while you eat lunch or whatever.
This charged my n5 from 14% to 100% in about 30 mins while playing a light game, and used roughly 1/5 of the total capacity.
I no longer charge my phones at night. I just charge this badboy. I've had it for a week and well, I haven't worried when my phone gets to 15% battery remaining by 12:00 due to heavy use and gaming. Neither has it ran out of charge before the end of the day, and it comes with 4 different adapters for varied devices.
It's perfect.
I found this new on eBay but you can find them anywhere, just make sure the get at least a 2.1A port for fast charging.

Hello everyone,
I hope to buy a power bank for my new Nexus 5.
I have made many search and I found that all power bank provide more that 1.2 A as output.
I noticed that the Nexus 5 official charger provide 1.2 A as output. So if I will buy a power bank that provides 2A or 3A, this will make problems for the phone battery ??
It is real that the important amperage charge the phone very fast, but this will not make problems for the battery ??

Ive got problems with the nexus 5's battery life aswell.
Now I'm using franco kernel and greenify and some other simple battery saving methods (no vibrate on key press, ...)
Feels like my battery life tripled it's juice!

Power supply life is an issue for everyone modern touch screen phones, besides the Nexus 5. Handsets increasingly becoming thinner, displays pack in additional pixels than ever, mobile systems are getting more source intensive, and battery power technology basically can’t sustain. The issue is additional evident using some smartphones than it's in some others, however, and the actual Nexus 5 confirms itself on the list of worst performers we've got tested lately with regards to battery lifetime.

The best feature I have ever had on a smartphone was a power saving feature from the HTC one.
So simple but amazing at saving battery life.

Proper testing conditions disagrees with you. You'd be hard pressed to find a more efficient quad core 2300 mAh phone ever made. The G2's 3000 mAh it can not match though.

solar charger for N5

Hello everyone. This is my first post so please be reasonable with me.I just bought a 6000 amh portable solar charger from amazon.ca .I have done a lot of reaserch on this and found that a lot of peopel online suggest using ground zero solar panels. Has anyone tried this with the Nexus 5?
I could use any feedback on this if possible. Please see attached.I will also post a update as well as nothing really mentioned any were .

Ground Zero or Goal Zero?
I have the Goal Zero kit from Costco and it works fine when charging from the battery pack (which is charged by the solar panel).
I wasn't patient enough to sit there and charge my phone directly from the panel.

Solar chargers
I ment to say Goal Zero.Sorry about that. I have been playing with my new solar charger and I must say that it is vary effective. I can charge my Nexus 5 in a hour and can charge it up to 3 to 4 times if needed. I would recommend this product if you need a extra power supply for small devices like 7 inch tablets or cell phones but nothing bigger(Referring to the EZO power charger from amazon.ca).If you want to do anything more then that the Goal Zero is what alot of people all over the internet recommend.(Goal Zero 12301 Nomad 7M Solar Panel ).Which is 55 dollars on amazon.ca.

I think the idea of a solar powered charger is cool, but, emergency situations aside, I can't really think of when I'd need this. I have an Anker 13Ah external charger, which would charge a Nexus 5 5.6 times from completely dead. That's almost a week of battery for the phone. I can't think of any situation where I'd be without a charger for an entire week (except, as i said, extreme emergencies, but in that case, the cell towers will probably be down and my phone would be useless)

Using external powerbanks?

I'm considering buying this powerbank:
http://www.amazon.com/gp/product/B00BQ5KHJW/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A294P4X9EWVXLJ
Many people recommend Anker but what about this model? I plan to use this not every day but for short weekend trips. My father plans to use this for his Sony Xperia Z Ultra.
I hear good things about Ravpower and Xioami (though you have to make sure they're the genuine kind).
Any thoughts?

I've become a bit of an Anker zealot lately and have bought batteries, a mouse, a keyboard and a bluetooth speaker from them. All work incredibly well and easy way beyond what the price suggests (sort of like the OPO).
As for the batteries I have the Astro slim 4500 and the 10k mAh bank and both work as advertised. The capacity on them seems to be lower if you're filling from empty (probably heat related) so if I NEED the batteries to stretch a short camping trip I'll try to do more topping off as time allows.

I use this exact same one, I love it because they offer 3A charging, large mah and fair prices. Very hard to beat.

It depends what you're looking for. The way physics works, you won't get the whole advertised mAh. You'll only get about 70% of it (rest is lost as heat) given that, a 10,000mah battery pack will only provide 7000 to charge which will only charge the one plus from 0-100% twice ONLY if you're charging the phone which while it's off. I'm looking at getting one that will harte the phone 3 times and that also has a a % indication on the battery pack. I've only found one for 15000mah and has the LED % indicator

Actually, the OnePlus has a good battery life, and you surely can make it run for 2 days easily with only messaging and internet. Though, I think a 10k mAh should be more than enough for a couple of days. I actually have a 2000 mAh battery only in case when I'm out of home for more than 24h but I've never used it. I'm also using the power Quick Tile and I think with the "energy saving mode" enabled you can last one and a half day easily
Sorry for my approximative english, cheers !
