I’d been using the Wirecutter-recommended Accell Home or Away travel surge protector for travel until recently. It’s really good, but it only has 2 USB ports and when I started traveling with an external battery, that was too few. One USB port for my phone, one for my tablet, and none for my battery? Sad. In theory maybe I stop traveling with my tablet but then I add in my headphones, which charge via USB, and I’m back where I started.
Plus I just got this watch, so.
Thus, I picked up Anker’s 6 port USB charger. It’s not a hub; it’s a small brick around the size of a very full men’s wallet that plugs into a wall outlet and charges a bunch of USB devices at once. I don’t imagine it’d do great with six items plugged into it, but it’s fine for phone and tablet and external battery. Anker’s other gear has performed very well for me (cables, car USB adapters), and this seems similarly solid from one trip’s worth of experience.
