Pass-through charging during a session
Plug in mid-session to keep your session going longer.
Pass-through charging lets you run a session while VOLTA is connected to a USB-C charger. If your battery is running low mid-session, plug in to extend your runtime.
How it works
When VOLTA is plugged into a USB-C power source during a session, incoming power (up to 24W in the device) supports the battery while the heaters run. At higher heat settings the heaters draw more than USB-C can supply, so the battery level can still go down while plugged in, just more slowly.
In practice: one full battery covers 60 to 90 minutes, and pass-through stretches a session to around 120 minutes. For longer sessions or back-to-back bowls, swap in a charged spare battery.
When to use pass-through
- Sessions longer than 60 to 90 minutes, where the battery alone might not last
- Topping up between bowls when you don't have a charged spare
- Stationary sessions at home or at a bar where outlet access is easy
What you need
- The included USB-C cable, or any quality USB-C cable
- A USB-C power source (5V/3A, 9V/3A, or 12V/3A all work)
Setup
- Start your session as normal.
- Plug the USB-C cable into the base of VOLTA.
- Plug the other end into the power source.
The OLED screen shows the charging indicator when power is connected. Keep an eye on the battery level during high-heat sessions.
Notes
- Pass-through only works in on-device charging mode. The battery has to be installed.
- Cable quality matters. A weak cable can cause voltage drops that interrupt the session. Use the included cable or a quality replacement.
- For the longest sessions, use a 12V/3A or 9V/3A USB-C charger. A low-power phone charger adds very little runtime.
