How can I recharge the Revolve Portable?

Use the charging cable supplied with the Revolve Portable and an adapter with 5 Volt, 1 Ampere and 5 Watt.
Charging the lamp should always be done indoors.

For first-time use, it is advised to charge the built-in battery for at least 8 hours.

For normal charging, it will take approx. 8 hours to fully charge the lamp.

A fully charged lamp remains lit for up to 20 hours (at 100% brightness) and up to 90 hours (at the lowest brightness).
