These days, you probably charge as many things over USB as you do over standard AC outlets, so it only makes sense to add some semi-permanent USB ports to your home.
Today on Amazon, you can get highly-rated duplex receptacles with a pair of USB ports for $16 each with promo code RLFQ6HCT. That’s one of the best prices we’ve ever seen on one of these things, and in fact, it’s the best price we’ve seen on a model with 4.8A of power shared between the two USB ports. These have proven very popular with readers in the past, even at higher prices, so be sure to secure a few before Amazon sells out.
