When you're packing for a trip it's easy to forget a few things, even if you've got a great, geeky travel checklist. If you forget your charger, the television in your hotel room can fill in as a substitute.
Although not the first time we've mentioned that TVs can charge USB gadgets (and do plenty of other things with their open ports), Redditor Mcahneriii notes that it's an important hack to remember when you're travelling.
I often travel with a single charger and multiple devices to avoid packing too many things, but I've neglected to use the TV as a spare power source despite knowing this tip. While not every hotel television will have this option, it's a good thing to remember in case you're in a bind or would find it convenient to have that extra charger without packing it.
