The selection boundary

This listing is included for its documented use context. It is not a hands-on test, best-price claim, rating claim, or performance guarantee.

What to know

Peak-amp numbers are seller test figures; what matters is keeping the pack charged — top it off every few months or it will not be ready. The 100W fast-charging is for recharging the pack and powering devices, per the listing.

Compatibility / use
