Kensington recently introduced a new USB charger powered by AAA batteries. The gadget will compete with similar products from Energizer, Duracell and IOGear. The dual-function charger can be used to power your cell phone when you don’t have access to power outlets.
Just realize that the AAA batteries inside are not going to satisfy power hungry phones like the iPhone. It’s more for entry-level handsets. The device comes with adapter cables and two sets of batteries so you can rotate them. It’s great for wireless mice and keyboards and is a good gadget to have around for emergencies.
