Urgent charging of players and phones

What to do if the battery of the phone or player is almost discharged, and the opportunity to charge it will appear only after a few hours (or even days)? A couple of solutions to this problem:

1. AA Battery Charging
If you have a stock of finger batteries or the opportunity to buy them, then this device is for you. Included is a solid metal case with a screw cap and a set of cables for connecting devices. In the photo - two cables for connecting Nokia phones (additional cables are purchased separately).

If necessary, a strap or key chain can be attached to the device.

The battery is inserted inside the case and closed with a lid. On the other hand, there is a simple board with a converter and a connector for connection cables.

When connected to the charger, the device displays the message “Charging in progress”, and the red LED on the charger starts to flash.

One good battery should be enough for 10-15 minutes of conversation.

2. Solar charging
A handy thing for hikes and trips in good sunny weather. In addition to the solar panel itself, inside the small case, there is a battery with a capacity of 1350 mAh, which can be charged from a USB or 220 V. socket.
a couple of solutions to this problem.

The bundle is rich: in addition to the charger itself, the kit includes a “220V to USB” adapter, a cable for connecting a charger to USB and adapters for 5 types of connectors (Nokia “thick”, Nokia “thin”, Samsung, Sony Erricson, Mini USB). To connect other connectors, there is an adapter to which any other device that can charge from USB is connected as standard.

The built-in battery can be charged both from the sun and from a power outlet or computer. The manual says that it takes about 10-15 hours to fully charge from the sun, and 4-5 hours to fully charge from an outlet or USB. The average charge time of a mobile device is about an hour (depending on battery capacity)

UPD. Both devices came to me from Germany as a gift.
AA Charging is for sale on Dealextreme for $ 5.62.
Such a solar battery is sold on Dealextreme for $ 14.78, except that it does not have a 220V adapter for our outlets.
