A better version of my most useful device is $30 this Prime Day

This Charmast power bank is the most useful thing I own. I already have the 10,000 mAh model, which keeps my phone, vape and other gadgets charged on the road, and the larger unit — twice the capacity in what looks like the same-sized chassis — is down to $30 for Prime Day, so I bought one.

My current model still holds the same amount of charge it did when I first took it out of the box two years ago. It has travelled the world with me and, aside from a few scuffs from being dropped on concrete and tile, remains practically flawless. What sets this design apart is the integrated cables.

Four cables — USB Type-C, Type-A, micro USB and Lightning — tuck into the side with a tough, flexible rubberised coating so they’re always attached and ready. They aren’t very long, but they work well flipped back to hold the charger with your phone, and they let you top up other devices quickly.
