How many times have you checked into a hotel room only to find a paucity of electrical outlets to charge up your devices? Or maybe you needed a quick pick-me up charge for your device on a long flight or train ride?
I really love the devices from Ventev, particularly these hub devices (see photo) that let you charge multiple phones and tables from one electrical outlet source. They really save you from packing a lot of transformers and other gear.
And for quick pick me up charge, my husband always carried his HubMax from MyCharge, which can quickly refill two devices on the go with its Apple Lightning and mini-USB cables. It also plugs into a wall outlet.
