I REALLY like the fact that Charge2Go have different connectors that can work with the same base unit. It really annoys me when manufacturers make you buy a new unit just because the connector is different.... not so with Charge2Go. Of course, the downside is you could end up losing the small cable, less likely if you leave it plugged into the base.
The base unit is very small... will easily fit in your pocket. The red LEDs flashes when it is charging the phone. There is no need to wait for the battery to charge up before using the phone... the phone is ready for use as soon as you plug in the Charge2Go. Nice user-centric design!
There are other small but useful details such as the small hole at the base cap for a key ring... you would have to find a pretty thin ring to fit.
The BEST part about this charger is it uses a standard AA batteries. This is key for emergency recharging! Next time you travel, leave the bulky charger at home...bring a Charge2Go with you instead.
