Portable battery charger

I'm going on vacation to a foreign country, and I need a portable battery charger for the road for my Galaxy Nexus. Can anyone recommend a good portable battery charger.?

I have the Mili Candy, great for a quick charge. On their website is a bunch of others that will give you a longer charge.

I have seen cheaper ones then the mili but I can't recommend any as I don't use them.

I have one of these from Amazon and works great with AA or 9 volt batteries. LINK
AA batteries should be available or you can just buy rechargeable ones (thats what I do)
Edit: This device doesnt recharge your rechargeable batteries, you would have to take along a charger for those as well which might be too cumbersome for you. Either way, just another option.
Then when you get home you can use it as a regular charger.
Have a safe trip!

External battery chargers

Hey guys,
Has anyone found a charger for an external battery that works well? I'm just talking about the 2100-2300 variety. Thanks guys!

I'm a bit confused. Would you mean external chargers, extra batteries or http://www.amazon.com/5600mAh-Exter...-66&keywords=samsung+galaxy+s3+mobile+charger such as this? Perhaps even an extended battery...

I have two.
First us the Zagg Sparq. Doubles as both a portable battery charger and a wall charger. Looks just like the old model Apple airport express wifi routers but in black. I get about 1.5 full charges from its battery but I never really go back to full, usually just a boost to about half from empty is how I use it. Has usb ports so you need to keep a cable with it but it charges anything with a usb charge interface. Got a set of 3" cables for mini, micro, and apple dock connector to keep the mess in my bag down.
Second one is a much smaller no name device with a micro usb plug sticking out one side. Got it relatively cheap. Only has enough to charge the phone back up to about 75-85%. But it is good for an end of the day boost.
A second battery would be better in most cases but these chargers are more generic so can use them on other toys too. Bought them to get an extra day or two of power when tenting.

This one charges phone or external battery or both and uses a regular micro usb for mains input so can be used in vehicle as well.

Hey guys,
My bad for not clarifying. I'm talking about the wall charger for extra external batteries

I just got this one its got this one for $20 off amazon its 2600mah fits nicely in your pocket so you can charge your phone while its in your pocket. A couple of problems with it is that it only came with a USB to micro USB cable but not AC adapter. It charges my phone pretty quickly but it only charged my phone about 70% before shutting off of course I was using my phone the whole time but it still should have had more of a charge in it. Also the unit its self takes forever to charge around 6 hours! But overall not a bad buy for $20.

Secondary battery charger?

Hi,
Initially i was thinking about getting a bigger 3000+mah battery or something but i've realized that i like the form factory of the GNex so i won't go for it.
Now i have 2 batteries the 2100mah and the original one that came with Verizon GNex.
I have looking for a external battery charger and found this
Has anyone here tried these, they seem to be the cheapest way to make use of both batteries.
Also the current wall charger i have reads the following:
input: 0.4A
Output: 5.3V=2.0A
Is the ebay charger in the above link close to the above specs as i don't know what they actually mean
Thanks in advance

I can't answer your first question but I can answer your second one.
Basically, your current charger is capable of charging the spare battery at a faster rate than the eBay charger.
The "charging rate" of 2.0A/2000mA versus the eBay charger's 0.8A/800mA.
When I'm looking for chargers, I prefer chargers that have an output of 1.0A/1000mA or greater so that my battery or phone is charged faster.
800mA is better than average. I'd find that acceptable.
I find most chargers have an output of 500mA. As a comparison, the OEM Samsung USB wall charger has an output of 1.0A/1000mA.
EDIT: In case anyone's worried about blowing up their battery using a charger with a higher amperage output then OEM, here's some reading material... bit.ly/xl2NPI
The only downside to using anything over 1.0A is that it may shorten the lifespan of your battery (the higher the amperage, the faster the charge, but it also comes with more heat, and more heat is bad for your battery).

What kind of wall charger are you using?
I bought a Cellet dock/charger. It can charge the phone and an extra battery at the same time. I mostly use it to only charge an extra battery. Sometimes it takes 4+ hours to charge a battery that is connected in the extra battery slot. WTF??? 4+ Hours?

I'm just using the OEM Samsung USB wall charger that came with my phone. It's sometimes listed as a "travel" wall charger. It has an output of 1.0A.
What's the output of your Cellet adapter (i.e. what you plug into the wall)? I'm pretty sure it has an output of 1.0A from what I've read.

Have you tried one of these?....IMO its better than carrying a couple of batteries around.

I am using the official HP touchpad charger, they are monstrous.
It charges the 2100mah battery from being dead to 100% with sync on in 1.5 hrs.
4+ hrs. is too long.
You can get on wallmart here or on ebay.
I haven't been this lucky with other chargers i've bought on ebay.

Ya i like these, but i would have to carry a cable and a battery at the same time, plus i don't have a tablet or any other gadget that uses microUSB charging.
On another note do these come with 2A charging instead of 1A??
if yes than i might just pick one up.

Alternative?
I've recently purchased this official charger. Does the job perfectly fine and is very small and sleek

combined external battery plus wireless charger

I got my nexus 5 (32gb white) last week and love it. I am searching for an exteranlnrechargable battery and found Anker Astro Series to be very nice. I am also in search of a wireless charger and some products could be found in different threads. I do not know if it is possible to combine the two functions into one. Please tell me if you have any ideas and suggestions. Thank you.

If you don't know, try googling it:
https://www.google.com/search?q=qi+charger+battery+pack
Don't own one myself, so i did just that just now.

Don't buy this one I just sent it back it isn't good as a overnight charger causes the phone to get very hot and reboot then starts to drain your battery down.

Thanks. It looks very nice. $55 is not very expensive. I assumed that it is compatible with Nexus 5 since it listed Nexus 4 in its specification. Any experiences with this charger?

I've been looking at getting one of these to use overnight and then take it with me for trips for the n5 and n7. Anyone else have experience with these types of chargers? If I plug it into a wall will it charge my n5 and the brick or will it charge the brick first then the phone or visa versa?

Lugulake Qi Charger/Power Bank. Combines both functions into one and can even charge another phone via USB while your phone is charging on the Qi pad. Heard it was really good.

I was seriously considering the Anker Astro E5 15000mAh External Battery until I wanted a wireless charger. Thanks for your comments.

BlakeJ said:
Sure, you can combine the two functions into one. Get a RAVPower Qi charger with built-in 4800mAh battery pack.

As they upgraded the surface, I guess there will be a upgraded power bank version on Amazon soon.

Hope it works as advertised.

if you short of power and need a external battery pack, why would you combine it with the lossy and slow Qi charging?

It looks like it can charge phone both wire and wireless. So just give me one more option when I am not in a rush since I am little bit worried about the slim micro-usb of the phone.

What was the choice?

There's a brand called metrans that combine wireless charging in a power bank , Google it in ebay.

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 ??

Best wired charger for nexus 5

Hi. Can you guys please tell me which charger you are saying. And which is the best charger for nexus 5 which takes less time to charge up the battery. I recently lost my stock charger and the other chargers I have are taking much longer time to charge the phone they are like 500mAh chargers so its taking long time. Can you guys pleas suggest me the charger.

Check another post in this sub forum. It has links to the BlackBerry playbook chargers, which are awesome and cheap.

The HP 2.1 amp charger is the best charger

I second this - bought a bunch of these chargers to use everywhere.

I'd go with the blackberry folding blade chargers.
There's a review thread someone did. Lots of people here have it. http://forum.xda-developers.com/google-nexus-5/accessories/hands-best-fastest-cheapest-nexus-5-t2729066
It's also so much cheaper than the HP touchpad charger. On amazon you can get anywhere from 4 - 8 chargers for the price of 1 HP.

Just use a USB cable with a MicroUSB port at one end. You always have a computer next to you.

OP was looking for something that can charge faster than 500mA which USB charging is limited to. At that speed it can take 4+ hours to charge the phone vs 2.5 hours with stock, and 2 hours with a 2.1A unit.

My GF got an LG G2 at roughly the same time I got my phone.
I've tried charging my phone with a wide variety of chargers, including the ipad 4 charger, as well as other 2.4A heavy duty chargers from other companies. I dont know why, but NOTHING is as fast as that stock G2 charger. It beats the "heavy duty" voltage stuff by a noticeable margin.
It does a proper quick charge on her G2, and while I've read that the nexus 5 doesnt really support that quick charge, it DEFINITELY does something.
It looks like this: http://www.lg.com/us/images/cell-phone-accessories/wcp-300/gallery/medium05.jpg

I am not sure if you will get the folding blade charger in India. You can buy the CP AD2 charger. One of my friend bought it and the Nexus 5 is charging at around 1300-1400 mAh. You will get it in Amazon for 550 rupees.
