Help me choose a good portable battery

[menachemposs]

I'm trying to choose a portable battery for my nexus 4 but there are so many companies out there and so many different types.
Can someone help me zero in on the better companies as well as what to look for in the specs?

Thanks

Mophie brand has always served me well. This is the one I'm currently using.

I am tempted to buy one. I was hoping that someone would make a case with a built in battery.

I haven't seen a case with a built-in batter yet.

NewTrent makes great battery packs. Their NT70T has huge capacity (will recharge your phone several times) and has an integrated MicroUSB connector cable that snaps into its side when not in use so less to lug around. I've had mine several months now (I use it with both my N7 and N4) and love it. There's a deal on Amazon right now (free 2 day shipping with Prime, as well) where you can get it for $50 and can pick up a smaller second pack, NT5200, for free (or you can get a wall charger, dual car charger, or stylus).

I had the NT5200 first, then picked up the NT70T later. The NT5200 is smaller, but the convenience of ht NT70T makes it my preferred unit. That, and the NT5200's LED's are ridiculously bright.

I stumbled upon this product a while ago on the website below and it's called Exovolt Plus Stackable Battery Pack.

I haven't used it yet but interesting thing about this battery pack is that you can add as many batteries you want to maximize the battery capacity.
Or you might just google it to find out. Good luck.
