Rechargeable 3-Output Mode 15000mAh Li-ion Emergency Power Battery

Pros: This is a pretty big battery ! Maybe the biggest capacity available here on DX !
It charges on 12V and outputs steady 12, 9 and 5V. 5V is on USB only, no jack output.
Good robust interruptor and dual color LED.

Cons: I'm not sure it's really 45Wh : it seems a bit too small for that and the screws are glued so I didn't open it.
Plastics are a bit cheap and bend in some places, like it's a bit too large for the actual contents of the package.
Shipped with an US-shaped wall-charger but that's pretty common here on DX.
The LED doesn't change of color when fully charged.

Other: Great if you have big mobile energy needs ! Will probably buy another one.

Pros: so i bought this mainly for my ipad 2. Sadly it carries a lower charge capacity than the ipad recognizes so it takes forever to download. I do however like that it has an on/off switch and many different outlets

Cons: no manual. no warranty. no instructions. Buy this if you need backup power and can afford to dispose of a few of these devices. Do not buy this if your on a tight budget

Other: cheap and useful. dont see this as the device that will solve my external power needs. Im looking in to buying an Anker external battery but sadly it costs to much

Pros: This is one of the larger batteries available that is packaged (rather than just shrink-wrapped). It provides 12 V for powering audio recorders. Make certain that the recorder will work down to about 10 or 10.5 V as this appears to be three cells in series based on the voltage readings I saw. It provides lots of power and brought the onboard 55 Wh battery to full charge (from probably 75% and powered the recorder for three or four hours and still was at a reasonable voltage.

Cons: A little plastic-y. Have to remember to turn the switch on for charging. No option shown for car charging.

Other: I would certainly buy this again.

Pros: It has a lot of power (see previous review) and I have used it a few times.

Cons: When I went to recharge it this week, the power adapter did NOT show green even after a few days of charging. All the LEDs are on (red on the charger and green on the pack) and the switch is on, but no green light on the charger. How do I know when it is charged? What happens if I overcharge?

Other: I don't know if I'd buy this again (repealing some of my enthusiasm from the first review).
