Charging

The Librem 11 requires USB-PD 12 V (exactly), and at least 2.5 A (30 W). The OEM charger supports this on the top port only.

The charger can offer higher voltages such as 15 V / 20 V, but it must have a 12 V mode to charge the Librem 11. Some chargers do not have this mode. Librem 5 chargers will not necessarily charge the Librem 11, but some newer ones will as the 12 V rating has increased.

The 65 W USB-C adapter from Purism can charge the Librem 11 (12 V, 3.0 A).

Battery

The Librem 11 has a non-user-serviceable internal battery: 26.6 Wh (7.6 V, 3500 mAh).

Runtime is currently about 3 hours of light web browsing. Suspend is enabled by default. Battery runtime while suspended is approximately 40 hours.
