What external battery pack are you using?

[SLAKY]

Hi guys. What external battery packs are you using? Can you please share your experience with it?
I have a big problem with the short battery life of my phone. I'm looking for an external battery pack and find tons of them, capacity from 2600mAh to 20000mAh and many at cheap price, when I go through Amazon and Ebay. I'm not sure about how fast will these battery packs charge. And it's hard to decide which to buy. Anyone can suggest?

For my phone and Android tablet I use a Trent IMP70D. Has 2 USB ports with 1.0 and 2.1A. For chargink uses MicroUSB which saves space as I do not need a spearate charger for the battery itself.

For non-USB charging you have to look at power monkey and the like.

I'm using one from Diginote: Computerland - De no-nonsense computerwinkel
This is almost the same as: Amazon.com: Anker® Astro Pro2 20000mAh Ultra-High Capacity Multi-Voltage (5V 12V 16V 19V) External Battery Backup Charger Power Pack for Tablets, Netbooks, Notebooks, Laptops and Smart Phones -- Compatible with HP, Dell, Acer, Asus, Toshiba Notebooks

Further I have bought a cable for my surface at: $12.00 - Wall Charger Cable for Microsoft Surface RT Surface Pro - LS002436 -

I can go into the bush for a week with my surface RT

Slaky --

There is a thread called External Battery Pack Option.

It is long, but has lots of detailed discussion of external batteries for Surface.

Thank you guys！I finally purchased one of the RAVPower 14000mAh from Amazon as it was on promotion. I paid $37.99 after the provided coupon code. It just arrived at my mailbox. Looks great! I'm going to charge my phone with it.
