This 4-port USB Wall Charger from Richard Solo goes right to the heart of traveling with mobile gadgets. Most of them are USB-chargeable, and you don’t want to carry around a wall charger for each, but you still want to be able to charge multiple devices at once. This wall charger has no standard AC sockets, just four USB ports. It is 100/240V and has a standard US-style plug (fold-out style); it works in other countries but requires optional adapters. It’s compact – 1.25″ x 3″ x 1.63″ and 2.8 ounces – and fits easily in your gear bag. It delivers 5V at 2.1A, and it can charge multiple devices simultaneously (“ability to charge multiple devices dependent on current drain”). It comes with a 3-foot USB to mini/micro USB Y-cable. This wall charger is normally $24.95, but you can save 25% until November 12 (while supplies last). Enter the code wall25 in the coupon box during check out, and the price is $18.71.
