Portable cell phone chargers

Cellular telephones have become necessary gadgets of our modern world. We use them for voice communication, games, surfing the web and checking email. All this consumes a lot of power and can result in a dead battery within a few hours if the phone is not recharged. Portable cell phone chargers make it possible to recharge a cell phone when you don't have access to a wall plug. Portable chargers are small enough that you can carry them on your purse or a key chain.

There is a large variety of Portable Chargers in the market. Some are as small as a lipstick while others are wallet-sized and unfold into an array of solar panels. Other portable chargers can also function as flashlights or key chain. This web page reviews the togoPower by [fuse]chicken

The key chain togoPower charger can also be used as a cable to sync with a computer by plugging the standard USB plug into the computer. This cannot be done during the charging process when the LED is on. This recharger is not suitable for synchronizing a phone on a desktop computer since the cable is too short and the cell phone can not be placed on a stable surface. However, it is possible to recharge the togoPower unit on a desktop computer.


The length of the USB cable is too short for
synchronizing a phone with a desktop computer.

Overall, the togoPower key chain charger and sync cable does what it is supposed to do in a convenient portable form. The key chain charger weighs 50 grams (1.7 oz) and measures 7×3 cm (2 3/4 × 1 1/8 in). One thing that would make this key chain power pack better would be if it could also function as a flashlight, but you will need to use your smart phone with the appropriate app for that.
