While I've been using the Solio H1000 as my in-transit charger for the past several months, I found a good deal on Woot recently for the Black and Decker Pocket Power-two for $20, shipped to my door.

While I like the option of solar-power charging that the Solio provides, in practical terms, it's not something I can use. However, the Black and Decker Pocket Power just stores power from your mains and gives you up to 16 watts of juice for up to four hours. Also, unlike the Solio H1000, the Pocket Power sports a US-style AC plug, allowing you to use whatever kind of AC charger you want. Pocket Power also sports a USB connector for USB-style charging as well. And yes, provided the total power draw is less than 16 watts, you can use both ports simultaneously.

The name is somewhat misleading, though. The manual specifically states that the Pocket Power should not be used in a pocket. Not that you'd want to put it in your pocket, given how big the device is. Posted by: Dameon Welch-Abemathy    Source
