✓ Built for dirt. Thick rubber corners wrap the case. You can toss it in your pack and stop babying it.
✓ Covered ports. A rubber flap closes over the ports. Dust stays out.
✓ Four lights. Tap the button. The small lights show how much charge is left. No guessing.

✓ Two at once. Charge a phone and a tablet at the same time. No one has to wait.
✓ 10000mAh inside. The maker's chart shows about three charges for a small, older phone. Big new phones get fewer.
It is late. You are at camp. Your phone says 3%.
Your stomach drops. You need it for the drive home. You need it to call home. You turn it off and hope.
Then you think of the pack. You pull out the power bank and plug in. The screen lights up. You breathe out and sit back by the fire.

✓ A light on the back. A bright light on the back helps you find the tent zip in the dark.

✓ Hooks on your strap. A fold-out hook on the back clips to a pack strap. It stays where you can reach it.
✓ Sun as a backup. The solar panel adds charge slowly. It is for a pinch. Fill it with a USB cable before you go.

✓ Clear label. The back shows the size and output, so you know what you have.
