iClever BoostCube+ 40W 4-Port USB Charger | $15 | Amazon | Promo code ICICWC40

It might seem crazy to you or me, but a lot of people charge their gadgets exclusively with the chargers that they came with. If they need to bring a phone, a tablet, and a Kindle on vacation, they’ll pack three separate USB wall chargers to power them.

If you know anyone like this, do them a favor this holiday season and buy them a travel-friendly four-port charger for just $15. It’ll probably be the most useful gift they receive this year.
