How long does the battery last, and how do you charge it?

According to our engineering tests, Clever can be opened thousands of times without a single recharge. When it does run out battery, Clever recharges extremely quickly using any micro USB cable and smartphone charger. Plus, you can always view your Clever lock’s current battery life through the official Clever App.

What are its dimensions?

Clever measures 80mm x 40mm x 20mm (including shackle). With a 5mm shackle diameter, Clever latches onto just about anything: lockers at school or the gym, suitcases, handbags and more.

Clever also features a patent-pending “Swing Shackle” mechanism that allows the shackle to lock and unlock with no vertical displacementresulting in a lower physical profile for tight spaces.
