You can currently get the HyperCharger with a Triton 3-in-1 charging cable for $39.99 at the PopSci Shop.

The use of carbon allows this pocket powerhouse to store a remarkable amount of energy in a small space. The HyperCharger measures 0.75 inches thick and under four inches long, but you get 10,500mAh to play with. That’s enough to charge your iPhone 8 to completion about 2.5 times over. In addition, the battery uses 3rd generation HyperCharging technology to deliver the power at speed.

The HyperCharger offers two ports, which you can use at the same time. You also get a NanoStik Pro pad, which allows you to attach the battery to your phone. Meanwhile, the durable 3-in-1 Triton cable lets you switch between Lightning, USB Type-C and microUSB connectors in seconds.

Normally $69.99, the 11K HyperCharger is now just $39.99 with the cable.
