Plug the supplied USB cable into the supplied charger (and the other end into a USB charging port...)
Slide your Secure Wallet in the charger, with the front of the Secure Wallet facing toward the side of the charger with the arrow

When the Secure Wallet is charging it will turn on and you will see a red charging LED next to the e-paper display.

When the Secure Wallet is fully charged, the LED will change from red to green

A single full charge on the secure wallet is enough for around 20-30 send transactions on and off the Secure Wallet

The quick-charge feature of the Secure Wallet will charge a low battery from 20% to 85% after a 1 hour charge, and will be at 100% charge after 4 hours.
