[SOLVED] Good external battery charger?

I'm looking for an external battery charger since I bought a couple extra batteries for my phone.
anyone have experience with a certain charger? Obviously I don't want something that will damage my battery but nothing that will break the bank either.
Thanks.

Anything wrong with the charger that came with the phone??

I need a charger that I can put a battery on so that I can use my phone out of the house and a second battery can be charging at home..

Yeah, sorry I probably should have been more specific but I dont know the exact name for them. haha
It's like the dock "travel" charger for just the battery, not the battery connected to the phone.
I havent been able to find something decent (crappy charging, made in china).

Ok a little update for those interested.
I ended up buying some cheap (REALLY cheap) charger off ebay not expecting too much but just experimenting.
The charger itself looks something like this:

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

}
The 2 metal prongs connect to + and -; the charger is able to read which is the + and which is the - no matter how you set the battery in there. The bottom part that pushes the battery toward the prong is extendable or you can flip it 180 if you have a really small battery.
-Flashing red and blue light means charging
-Dull red light while plugged in means fully charged
-Dull red light while not plugged in but with battery set up means the pins are set up correctly on the terminals
NOTE: do not take batter off/put battery on while the charger is plugged in. It can ruin the battery.
The exact one i bought:
http://www.ebay.com/itm/270908124203?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
(no problems with the seller, they actually sent me a few free ones due to a misunderstanding)
Now for the review and my experience.
Pros:
-Fits any battery, interchangeability of pins (differentiating + and -) means you can fit any battery really
-Has a side USB port so you can charge a battery and plug in your USB cord to the phone and charge it at the same time
-Voltage input is 110-220V so (with an adapter) you can theoretically (will test this summer) plug this charge straight into an european plug or north american plug.
-No problems so far with over charging; Charger stops charging the battery when it is full
-Has a light to tell you when the battery is done charging and when you have the pins connected correctly to the battery
-Compact; Small and plug folds up into unit.
-Charges a fully dead battery quickly.
Cons:
-No instructions when I first received this product (i know what you're thinking, how hard could it be to just charge a battery but I was reluctant to rely on the self detecting terminal feature)
-While charging, the light on the unit (the one i posted/bough) flashes red and blue like cop lights and is very bright so it might be a problem if you are plugging it in overnight in a bedroom. Also this is a normal function of the charger but i thought it was malfunctioning so they sent a new unit but then figured out its normal.
-Looks cheap
-Dont know how long it will last for (really cheap so buying another one isnt a problem)
-Noticed that after i pull a battery off the charger and use it the phone states it is at 99% (undercharged) although if i try to bump charge a fully charged battery it wont charge more. This could be a problem with my battery/phone/etc.
-Nothing else really
So final verdict on this product:
Its a great, affordable charger; works great if you are traveling and need to charge an extra battery. Will fit the Incredible 2 extended batteries and technically virtually any battery. Its pretty easy to use once you know what the color lights mean and how to set a battery up.
If anyone has any questions or want more pictures of this product just reply in this thread. Hope this helped out anyone looking for a product like this.

i just wanted to jump on here and say rthank you for posting this. i just oredered one for myself. i droid incredible 2 usb port took a dump on me and now have no way to charge it now without taking it apart and replacing it. thanks again for this info. it will hold me over till i am ready to fix the usb port or get my upgrade. i will just the ftp app from the play store to transfer my files till then.

so just an update. just recieved this device today in the mail. only cost less than four dollars and is working perfectly. thanks again for this post.

Monoprice 2800mAh portable battery box

I just got a portable battery box (2800mAh) for $14 from monoprice. (LINK)
Nicely built, relatively small, and about to test whether it will give me 1.5 full charges as mAh would suggest (2800mAh / 1800mAh on HOX = around 1.5 charges).
Box itself doesn't come with any charger, but is able to be charged by any charger with Micro or Mini USB connector (yep, it has 2 inputs).
Output is a male MicroUSB connector that fits HOX nicely (duh!).
Output: DC5.0V 800mAh

}
I'd imagine if you want to use the phone while charging from it, you can connect them with a female-male MicroUSB connector.
The charger has a button that shows the charge level of the box with 25% increments (4 lights).
Has another light for "FULL".
As soon as I connected the box to HOX, phone immediately showed that it's being charged, as if from the regular charger. Not sure what the current is, but it may come across as slow charge (USB port charge) as opposed to AC charger.
So far I tested the charge over 10 minute deep sleep period, and I got this:
With the box, in average HOX charged for 2% every 10 minutes.
That would suggest that it would take this box 8.3 hours to charge HOX fully, which isn't bad at all, considering you're free to use it while it's charging.
Over next day or so I'll try to completely discharge the HOX and charge it overnight from the box. I'll see just how much this box can spit out.
---------------------------------
EDIT/REPORT:
I discharged my phone to 5% yesterday, disabled wifi and BT, and connected it to batt pack to charge overnight.
It turns out that this batt back is crap.
Overnight, when phone was in deep sleep with wifi/BT off, a full battle pack charged my HOX only by 55% (I charged the batt pack before using it). Even considering some small drainage during charge, I'd say this pack actually acts if it had just over 1000mAh or so, nothing close to 2800.
Oh well, gonna return it and keep looking.

shouldn't this be in the accessories forum?

Hate the ones that plug right into the phone like that. Pretty much makes the phone a huge pain to use. I would rather spend the extra money and pick something like this up

That's a good option too, although I actually like that monoprice's sticks right into the phone, so you don't have to carry a cable with u.
Also, it seems smaller and cheaper.

I know of certain defense organisations that allow the fixed connectors but not those with detachable cables. Disallowing the cables reduces the risk of the cables being used for data transfer.

huh?

It's a security standpoint from Defence services (IE: Australian Army, etc) who wish to minimise security leaks. A data cable can be used to link up other devices, not just the charger.

Okay, and I guess if I were flying in outer space, my suit was venting air, and the only thing that would save me is connecting a batt pack to a phone - in that situation a cable could freeze solid to a connector on the batt pack, making batt pack unusable, and thus killing me.

WRONG!
That's when Iron Man comes flying to the rescue thus saving your life and getting an autograph that you could sell on eBay for some money and covering your costs of the HTC One X.

OK well, turns out that this batt back is crap.

External Power Backup 3000-3200mAh

Hi everyone.
Be care full all things of this kind of battery is just publicity nothing real.
Here is how it's look

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

Inside is just a regulator for charg internal battery and a power up convertor to get 5V
The main battery who run this external battery is just a big flat 2800 mAh 3,7V battery more exact his code is YY 426390P 3.7V 2800mAh 12YE005.
Price tell you how much is plastics, how much is true and how much is publicity.
Here is the pics with image from what is inside.
Power Board covertor up/down from 5 to 4.2V max (that much can take Li Ion battery) when charge extender battery and up convertor from 3.7-4.2 to 5v to power your phone.
All parst who make the extender
The back cover of extender
The EXTENDER BATTERY 2800mAh not 3200mAh and never will get 2800mAh as he convert his power to 5V wher will lose some power on convertor (the button for on/off get hot when is used to power your phone)
Make a litle ajustment for hole of back camera and flash because when you shut in low light and have flash on or auto the white around flash will get back on your camera and picture will get unclear and with to much shadow. I will got a permanent marker black and make the hole black around camera and flash. In this way i can take a pic w/o get some noise from white.
Here is things who get broken easy w/o meaning i wish to do that i never know when i did that but i did it
As advice if you want a battery extender dont get this kind better buy an another 2500mAh and you get more power than from this.
Or use and inside replacement battery than external power battery except the price is very cheap.
Remember this batterys have some power to lose when get charge your phone because is a convertor who get hot (more or less ) but that means he lose that power.
Using my old 3.7V 3000mAh battery from Galaxy I9000 give me more power than this Extender and was only 10$ instead of 19$ who was this.
For around 10$ will worth and not you buy it for extend your time to play with phone but dont expect to much.
Hope some will get this value at least i will feel good because not all got cheat by numbers

Bought one of this (black) on ebay for £14.99, and I can tell you that it can not charge the phone battery over 85%. Phone gets excessively hot whilst getting charge. Also, IT TAKES FOREVER TO CHARGE UP THIS THING. Standard battery charges up in about 2.5 hours but it takes more than 8hours to this power pack.
NOT RECOMMENDED.

Sigh, and I wanted to get one for my Note. I guess it has some issues with build quality. :crying:
Anyways, thanks for the heads up.

I nearly want to bug exactly this type of power bank. Now, change my mind tp buy cheap extended 5000mah instead.

Get 2 this even they dont have real 5000mAh will get more than 1 as 2600-3000 and is a pair of 2 so you will have 3 battery for a very low price and 2 of them it will keep you all day long using alot.
Here is the link of what i order.

Thanks for your recommend link. So, cheap 5000 isnt really 5000. It will be less than that. So i need to prepare 2x 5000mah for me to last a day long. I can order from ebay. Maybe will search other thread to buy it.

Hoping for a reply on this old topic..
Sorry for bringing back an old post, but I have a question about this. I actually bought one of these long before I ever read this post, and to be honest up until it completely stopped being able to charge my internal battery, I never had one problem with this case, and actually really liked it. All that came to a sad halt when one day, it just stopped being recognized by my Galaxy Note when plugged into it. Which mind you really made no sense to me because if I plugged the little Mirco USB tail to another device that could be charged by the same battery and had a Micro USB female to accept it, it was picked up and had no problems charging it, as well, my Note could be charged by any other Micro USB charger, so why all of a sudden it stopped being able to be charged by this case/battery is beyond me since both work fine unless plugged together. I contacted the place where I purchased it and they did send me out another one free of charge and told me to keep the one that wasn't working anymore.
When I found this post, I decided to open the the broken one, and googled the number on the battery "426390P" which was the only reason I found this post. This post actually surprised me because up until this one stopped working, it was working perfectly fine on my SGH-i717. I mean it charged the battery everytime to 100%, sometimes it would charge my battery about 1.5 times before I would have to recharge it. I thought it was the best case I have ever used quite honestly.
So now the real reason for replying to this post. Do you guys think that if I could find a 3.7V, higher mAh battery (or even make my own) that would fit in the case, it would work with the upconverter board that is already inside? I am no electronics expert, so I don't know the functions of all the pieces on the board, but I figured if I could find or make a new higher mAh battery that would fit inside, not only would it beef up the longevity of my battery life on my device, but it would allow me to keep using a case that I actually like and love the way it fits with my device and since I have the black case, I do not have the glare issue with the camera nor any shadowing issues.
I am curious as to what you guys think..
Thanks in advance!

The problem with the types of solar charger that you posted is that they charge slowly. And exposed to direct sunlight, it might heat up too much and damage the internal lipo.
IF you just need a power source, get a portable battery. They are cheaper and works better in the long run.

Correct about the solar panels, at least with current technology you just can't get enough energy from something this small to justify the added complexity/weight/price.
Unless you are away (as in no mains and no "car" power) for weeks they aren't worth it - and if you are away you still need a more serious panel.
Just get one of the external "power packs" and top them up quickly over a few hours when you get the chance.
As a side-note the battery in Note is pretty big already and I suspect the charging circuit from the phone is quite far from 90%+ efficiency. Bottom line you need to get a beefy external battery; I'd say 5000 mAh is bare minimum if you want to get you through the day if you use the phone much.

So the 10.000 Mah would be good, if i get the chance to get a refund, as the delivery is already 20 days, i am going to buy that one.
Regards, Tomaat

Also, this will ruin the battery, when it isnt recharged with the correct amount of electricity right? Just as when you charge your phone with a car-charger og usb from the computer..?
In my experience, if you want a fully charged lasting battery, you need to charge with electricity from the wall...!

Huh?

This is what I think of Solar Charges, if someone is interested. This is a nice small article about how good they actually are.

You need a NEWTRENT. IMP1000

I am not Baekdal, but I am a subscriber of his work. I just thought that it might have been interesting for the discussion mentioned in this thread. I also consider myself an environmentally conscience person, but as the article points out not everything that looks green is green .
The solar charger is much less environmentally friendly than the electrical grid, which means that it will not save you money nor will it save the environment.
I'm glad you've enjoyed it.

Battery Cases? Slim battery pack with quick charge?

So coming from a Samsung Note 2, 3,and 4, I'm missing the peace of mind that carrying around a freshly charged spare battery gives. I always felt lame tethering a phone to a battery pack while waiting for it to charge. Well, I love this Axon 7, so there's gotta be some auxiliary portable power to make up for that.
I ordered This portable battery from Amazon that is supposed to be the slimmest portable battery that still has Quick Charge. I'll have to see how it works/fits and report back. If anyone has seen anything else similar, please recommend.
I did find a 6" USB-C cable to use with it so there's not a lot of extra cable to keep coiled when charging.
Also curious if anyone has seen a battery case for this thing?
I don't plan to use them all the time, but sometimes I'll be away from a charger and I need to communicate with work.

I'm using the Xiaomi power bank pro (10Ah) that has USB Type-C and also Quick Charge and my phone is charging insanely fast (30 min to 80%). I got the powerbank for 25$ on aliexpress.
ps: that 5Ah power bank in the link you posted is a joke, you will be able to charge your phone just one time if the powerbank is full. ( real capacity around 3.5Ah).

Thanks for the feedback - I'm actually looking for the slimmest/smallest power bank that I can get to charge in-pocket, as I already have a large 14,000 one that has QC that's about the same size as the Xiaomi one you mentioned. I only care about a single full recharge cycle - but one that does it as fast as possible for this need.

If you are happy with one charge then go for it.

I love these tiny phone-sized chargers as well - one charge is plenty for me as well (usually only need it when I'm walking around all day as a tourist or something). I just wish they would start to make some of these with USB-C cables built into them. I used to have one with built-in USB-micro and lightning adapter and loved it - when it was connected to the phone it was just like having a charger case in your pocket anyway...

Yes, I used to have one with the built in cable, too and that's actually the first thing I looked for, but being that there's not a lot of USB-C devices yet, I wasn't surprised that none existed with the built-in cable. Would be awesome if someone made one, though- I would immediately buy that if it was a single-charge slim w/ Quick Charge.

Just wanted to post my findings and pictures of the iKits unit.
Note that the shortie USB-C cable I ordered separately and does not come with the iKits unit! The iKits has a standard micro-usb that it comes with.Also be aware that the battery is labeled QuickCharge 3.0 - but that's only for charging the battery itself - I believe the capability to charge the phone is only at QC 2.0 (you'll see this sort of explained in the product description on Amazon link below).

I ran my battery down all day to about 34%. Plugged it with this cable and battery unit and was to 100% in a little over an hour, so I am happy with charging speed. Also in the battery stats "power management" area of the Axon, it definitely stated "Quick Charging" during this period.
I'm still interested in a battery case if anyone runs across one.
Here are the links to the cable and charger on Amazon:
$6.88 6" USB-C Quick Charge supported cable
$29.99 iKits 5000Mah Quick Charge 2 portable battery

So does anyone know of a case that fits the Axon 7 that has a built-in battery, similar to the Morphy JuicePack?
