Speaking of stuff you can buy from Amazon — with affiliate links that could make me rich — I highly recommend Anker’s small 20-watt Nano chargers. Basically, they’re the size of Apple’s classic 5-watt chargers, and thus fit almost anywhere, but they charge at the same speed as Apple’s much-larger new 20-watt chargers. These new models from Anker come in four colors: white, black, lavender, and sissy blue. If you or anyone you know is getting a new iPhone soon, I would strongly recommend one of Anker’s chargers over Apple’s — same speed, same price, much smaller, and a few color options to top it off.
Another Anker charger I’ve been meaning to recommend is the Atom PowerPort III Slim. It’s a 30-watt charger currently on sale for $19, and what makes it different is that it’s, well, very slim (including folding prongs). This charger will fit behind furniture that’s pushed up against the wall. It’s small and lightweight too — here’s mine next to a matchbox for comparison.
