Questions about this item

How often will the internal lithium battery need replacing?

The sealed lithium pack is not user-replaceable; after several hundred charge cycles its capacity will drop and the whole unit will need to be swapped.

What limits continuous 100W USB-C PD output during all-day use?

The 74Wh cell can supply 100W for roughly 40 minutes before voltage protection cuts output, so sustained load is capped by total capacity.

How hot or loud does the XP-20 get when recharging in one hour?

The unit has no fan; fast recharge warms the case noticeably but stays within normal operating temperature and produces no audible noise.
