Tired of your battery dying after only a few hours of operation? Looking for a Dynamo on-the-Go? Try the Ravpower RP-PB09 Element. It’s ruggedized - in a manner of speaking - and completely portable. But I wouldn’t go throwing it around; it’s a lithium-ion battery charger for lithium ion batteries.

Dynamo on the go

This little camouflaged unit is multi-functional. Not only does it work with almost all manner of portable devices such as, iPad, iPod, iPhone, windows phone, tablets and android devices, you can camp with it as well.

The Ravpower RP-PB09 Element stands about 3.7” x 2.3 x 0.8 inches tall and weighs a mere 6.3 oz. The cool part of the device is that it has a telescoping flashlight (~ 5 inches of surface area @ about 5 watts of light; enough to read by or simply light your tent. That’s cool.

The specs in English:

The RP-PB09 Element will light your way for about 8 hours with no problems. It comes with a top-side key-ring and clip to hang in your tent or on a post. Included with the charger is a mini-USB to USB cable for universal connections.

And with 7800 mAh it can charge your device twice from > 0 to 100% DOC for about 500 cycles. After that, the battery charge retention maxes out at around 65%. Still, pretty good considering 500 cycles with a duty cycle of once a week works out to about nine years. About $3.50 a year for piece of mind and the cost of charging the unit is so minimal, it’s not even worth mentioning.

The specs add up to a worth-while purchase. The device is marked down from $89 bucks to less than $30. Charge time for the Element is about 3-4 hours from < 45% and your mobile device should be fully changed in less than 3 hours as well.

One last thing: Ravpower does not have a recycling program in place, but most cities – like Miami Beach – have several private and city/county programs in place. It’s a lithium ion battery pack; don’t just throw it in the trash when you’re done with it; recycle guys and gals.
