Charging VOLTA: on-device and external

VOLTA has two charging modes: charge the battery while it's installed in the device, or remove the battery and charge it separately. The external method is faster.

On-device charging (24W)

1. Connect the USB-C cable to the port on the base of VOLTA.
2. Plug the other end into any USB-C power source.
3. The OLED screen shows the current battery level and charging status.

This method draws up to 24W.

External battery charging (36W)

1. Unscrew the base cap and remove the battery.
2. Connect the USB-C cable directly to the port on the battery module.
3. Plug the other end into any USB-C power source.

This method draws up to 36W, charging the battery noticeably faster.

Supported input speeds

VOLTA accepts USB-C fast charge inputs:

• 5V / 3A
• 9V / 3A
• 12V / 3A

A 12V/3A charger gives you the fastest charge in external mode. Lower-wattage chargers still work, just more slowly.

Full charge time

A full charge from empty takes about 1 to 1.5 hours under fast charging. Standard USB-C chargers may take longer.

Runtime

A full charge gives 60 to 90 minutes of session time, depending on heat settings. Higher heat uses more power. For sessions up to 120 minutes, plug in for pass-through charging or swap in a charged spare battery.

Charging behavior

• The device can be used while charging (see the Pass-Through Charging article)
• The battery is safe to charge inside or outside the device
• Both methods deliver the same total capacity (5000mAh)

Best practice

Charge to 100% before each session. If the battery drops below 50%, we recommend charging before powering on. A session started on a partly charged battery won't last the full 60 to 90 minutes. If you're running low mid-session, plug in for pass-through charging or swap in a charged spare.
