2x Battery + charger 2000mah($13.00)

Gonna try them out...not sure what i'm gonna get but for 13 bucks worth a try
http://cgi.ebay.com/2x-2000mAh-Batt...330459330057?pt=PDA_Accessories#ht_4942wt_911

Highly doubtful 2000ma batteries, probably 1500ma batteries that are really 1300ma. Tutoit on ebay I have 2x1500ma batteries for a 9.98$ shipped with a charger, I would get that instead.

yeah, either get the 2 1500s and the charger for 11 50

or the 1800 and the charger for 11 50

I was just looking at this... seems like a great idea... the extra charger allows you to keep a second battery charged without using the EVO to do it. Even if it's really a lower rated battery... still a good deal.
Did you try it?

I ordered it, but still waiting...those hong kong shipments take a while, i'll let you know as soon as I test it out

I have a set of the 1500 mah batteries with the charger as was posted above, and I have no problem with them. I use my OEM battery most of the time, but sometimes it is handy to have some fully-charged back-ups. Honestly, I don't see much of a difference between what my OEM battery lasts and the knock-offs. For the price, you can't beat it.

so how are the batteries?

normally i would stay way from cheap Chinese crap on eBay, but with what i read here on the xda boards in regaurds t othe ok qualitybeing good enough that they might work out, so i ordered 2x1850 plus charger from ebay. i dont have time to do any real testing but i can say that:
1 not having to charge the battery from the phone is nice
2 i always have one on the charger, one in my pocket and one in the phone.
3 charging in the base seems to get me a better charge
4 i cant tell a difference between oem and knock offs, although you would think that the 1800's would last longer than the 1500oem but we know how that knock off crap goes. in my book if they are the same as oem, regardless as to what they claim and dont require a bigger back plate, then i guess that's good enough.

The 2 from tutoit or what ever the sellers name is work great last as long or longer then my stock battery. The charger also gives a better charge to the batteries then I get through my phone I'm talking extra hours when I charge with it.

I got this and it's a good deal for the price.
The batteries aren't as good as oem. Probably last 75-80% as long.
The charger works well though and it's nice to have a couple extra batts laying around. I've only cycled them 4 or 5 times so I suppose the life could improve...time will tell.

I Have a number of Minor issues with mine. Must of gotten a bad set.
1) USB port on the charger does not output enough juice to charge the phone (Accually Locks it up until I unplug it)
2) Charger seems hit or miss on recharging the Stock Battery. I've left it plugged in all night and come back to ~20% charge when I pop it in a number of times
3) Random Screen cut off when charging the Replacements IN the phone.
So I only charge the Ghetto batteries in the charger provided.
That being said, I STILL think it's a great deal and more than happy with my purchase. I have 2 spare batteries for my phone (Or the wifes CDMA Hero) and a way to charge one w/o having to leave my phone behind (I don't have to babysit my phone for a charge, If someone walks out of the poker room or party with my charger and battery it's no big deal) The 2 China batts. are just emergency tanks, The Red one gets put back in as soon as I get home.

Best Purchase at twice the price.
Don't wait press the BUY NOW!!!!
Loved the first set so much that I purchased a second set 2 weeks later. I keep 1 set at work and 1 set at home. I always carrying a fully charged battery in plastic bag in my pocket. I love the EVO but hate the battery life. The first month I owned the EVO was hell for me having to carry a power charger and cable everywhere. I hated having to plug my phone in every time I found a power outlet worried if I didn't I may find myself without a phone when I needed it or having to fight everyone at the airports for power outlets. Now when I'm low on juice, I just switch batteries.... BUY NOW you'll never regret it....

I purchased 2 3500 batteries with new backs on e-bay for $22 and change. They work great I can go for over a day with fairly heavy usage.
Only minor problem was that with the phone thicker my silicone case doesn't fit as good. Extra weight no problem.

Yeah one thing I have learned from buying these types of batteries and charger is that they don't like to charge the OEM batteries but charge the cheapo ones just fine. I've noticed it on alot of things not just phone batteries.

buy it for the charger
i bought a 2000mAh that turned out to be a 900mAh so i would only buy it for the charger.

I wouldn't recommend the 2 x 1500 batteries plus charters the 1500's seem like a 1300 or a little less I would say try get the 1800 one from eBay they have a lot of auctions for them so all you gotta do is be patient and try to get for cheap that's what I'm tryin to do

Just ordered one of the 1800mah.. will see how this works out!

External Batteries

I was just wondering whether external batteries are generally quite reliable, and if so what the best brands are to go for? I am looking for a relatively powerful one - I am not afraid of a little bit of cost, but obviously I don't want to spend masses.
Thanks

Ive got a New Trent and its well built and reliable. The 11000mAH will last you for several days. Have a look on Amazon.

I have a "Just Mobile Pro" or something like that.
4400mAh with 1000mA output.
But the EasyAcc 5600mAh (which I don't have) does sound better and cheaper (on Amazon).

Second new trents 11000mah one that thing is a beast

Thanks not heard of New Trent before. Looks good. Can you confirm it's output charging current though? I can't find the spec on it anywhere. I'm assuming it's the full 1A, as it says it can charge an iPad, but could you please confirm? Looks like I'll be needing one!
Cheers.

Flashlight feature's a nice touch.

isound portable external battery. Has built in flashlight too. Comes in two flavors, 16000mah and 8000mah.
If you look around you can find it cheaper elsewhere

It's good and bad . I was on the train heading home from work and I was charging my phone with the Anker charger. I accidentally pressed the power button twice and the flashlight turned on. Sitting across from me was this fairly attractive woman with a skirt on. She automatically crossed her legs and looked at me weird. I hope she doesn't think that i'm a pervert.

Hah! Good thing I didn't have a mouthful of soda there...

Good thing to remember with external battery packs is that during usage some of the charge goes to charging the battery while some is lost in heat. I think I read some where its normaly 30-40%. So for example a 11000mah battery will give you some where near 6600mah of charge so about 3 and half charges of the HTC One X.
I'm considering either the:
TeckNet® iEP387 7000mAh Dual-Port 2.1Amp Output Universal USB Battery Bank

The heat loss is inevitable but the capacity should be unchanged.
What the heat loss means is that you need more than 11000mAh to charge up the full 11000mAh battery due to the losses.
The tecknet is very good value. I am considering it at the moment

Yes but I'm talking about in the other direction. So once you have 11000mAh in the device and you charge a device that take 1800mAh you will actually use aprox 2520mAh in doing so. My numbers and calculations maybe a little flawed but my point is that you cant do a simple 11000 / 1800 = 6.1 charges as you need to take into account heat loss which is around 30 - 40% (so I read on one of the amazon reviews)
Either way both devices are nice and cost quite reasonable.

Have got the Tecknet IEP987 7000mah battery myself. Has run through two charges of a sensation XL and my Fiio Headphone amp, and still around half full.
Am more than happy with it.

Ah yes of course. Did not realise you were talking about the other way round charger>>phone
Not sure how efficient but if say 10% loss, we still get around 5 times charge with a 11000mAh batt. to a One X.
I am leaning towards the 7000mAh. Not sure if I need it or not...

Also don't forgot not to simply divide the battery pack's capacity by your phone's battery capacity to see how many times it will charge, unless you are charging it with the phone turned off.
With the phone on it is obviously using the usual amount for running the phone, whilst it is being charged. Add the current being drawn for keeping the phone running (say 250mA when awake) for the time it takes to charge (for me 2 hours) and you are looking at 500mAH. Add that to the capacity of your phone battery before dividing it by the capacity of your battery pack to figure out how many charges you'll get from it. Figures used are just for example purposes. Use a current widget if you want to know how much your phone is using.
Plus like a phone's battery, a new battery pack will take several charge cycles to reach full performance. Where as with a phone's battery which only takes about 2 weeks (charging it every day), a battery pack will take that much longer to get the full performance out of, as you wont likely be charging it more than once a week/month.
And then there's the battery indicators. These New Trent ones look sensible, but I once purchased a Proporta Turbocharger 5000mAHr unit. It had three blue LED battery status lights that were always on if charging. If you looked directly at them they'd burn your retinas out your skull. They could be seen from space. Stupidly and comically bright. They HAD to eat into some of the capacity.
Copper losses over the cable at the distances involved in your average charging cable will be negligible. If you really want to reduce it, don't use those silly skinny retracting yo-yo charging cable things that some of them come with. Use a decent quality USB to microUSB cable. The higher the guage of the cable and quality of copper, the less volt-drop there is. I keep a good few of these kicking about at home as they are well made but not too costly, and come with a nice cable tidy clasp...http://www.ebay.co.uk/itm/GENUINE-NOKIA-CA-101-CA101-USB-DATA-CABLE-LEAD-5230-/140579882085?pt=UK_MobilePhones_MobilePhoneAccesories_MobilePhoneDataCables_JN&hash=item20bb36c465

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).
http://www.amazon.com/gp/product/B00FS1NTMW/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
*not much but you can save a little here:
forgot to mention you can Save 5% on Qi Wireless Charger Transmitter 10000mAh Mobile Power Bank(ASIN:B00FS1NTMW) when you purchase 1 or more Qi Standard Wireless Charging Receiver offered by Docooler. Enter code 3VYHPR39 at checkout.
Enter code 3VYHPR39

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

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

it does shut off once it gets a full charge, using the cable as a powerbank. Never tried QI as a bank doesn't make sense so don't know this way.

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)

[Q] Best experiences with external battery backups?

Just ordered a Zenfone 2 to replace my old S3. Love the phone, but hate the non-removable battery. Took the leap anyway because of the price. What are your best recommendations for battery backup units in the ~6000 mAh, ~12000 mAh, and ~20000+ mAh ranges? I figure I can snag a small backup that can fit in a pocket and a larger one I can leave in my car/bag/backpack. Which ones have you guys experienced that are long lasting and charge effectively? Ones that are resilient? Anything to the gimmicky seeming solar charging backup units from the like of ZeroLemon or another producer?

Aukey has a "Quick Charge 2.0" battery pack that should quick charge the phone way faster than any other option out there. Other than that I'd just watch the usual deal forums, etc. to find well reviewed models on sale.
My assumption has always been that tiny solar panels probably take forever to replenish your battery pack, but I can't say I have any firsthand experience.

The Aukey ones work well, I have 2 of them and they quick charge just fine and will give you ~2-2.5 charges depending on your usage while charging.

They are surprisingly cheap! $30.00 on Amazon for a 10,000 mAh version. That looks like a good rec. Do you have any experience with ones in the range of 20-30k mAh?

I would ONLY buy Anker brand. a lot of usb mobile batteries dont have power output to charge a phone that is also in use, and also have a heavy degradation after multiple uses. I was in a jam and bought a second battery at a CVS when i was out of town on business once and left my Anker brand at home, and after 3 uses it no longer could charge my phone faster than i was using it (talking on the phone).

Is the lifespan of Anker brand backups well known to be good? I'm thinking I'll buy two of the same unit so I can quickly swap them out of my bag when they die.

I'm getting the Mi Power Bank...the 10000 mah version can be had for $14 usd. Only downside is you have to wait for the "flash" sale. There will be one tonight at 9 central time(US).

Why don't you guys try the Asus Zenpower. I bought it with my phone for a package deal and looks very solid! Small too.. though its heavy.

I looked at getting one....however Asus wanted to charge $14 for ground shipping....ordered the Mi Power bank earlier....and they charged $5 to ship. With stock in the US, there is no way Asus should be charging that much for ground....Express shouldn't cost that much! Also....I wanted the Mi Band lol

I ended up ordering two of the 13000 mAh and one 6400 mAh backup, all from Anker. They were all Amazon Prime so I got free fast shipping, and they offer their version of Quick Charge so it should be a solid option for me. I'll update with my experience after I've had them for a bit if anyone cares.

Oh I am sorry to hear that man. Did you check eBay? Coz i got mine with the phone. If i deduct the phone price, the zenpower was only $10 plus shipping was free coz it was with the phone anyway. Mi is equally good. I am done with massive brands such as Samsung.. we mostly end up paying for their advertising, marketing and brand name.
