WHY THE PRICE IS JUSTIFIED

Independent testing measured 82.7–84.1% efficiency and only 41.7–43.7°C at 100W discharge. The money buys measured electrical performance, a useful display and cable integration, not a logo.

MATERIALS

HousingReinforced PC/ABS composite

Keeps the 428g package rigid while permitting controlled heat spreading.

Thermal layerGraphene heat-spreading material

Spreads localized controller heat during 100W operation.

Integrated cablesBraided polymer insulation over copper

Resists kinks and fraying better than plain PVC leads.

CRITERIA

9/10

Usable Capacity

Measured 82.7% at 5V/3A and 84.1% at 100W; about 63Wh delivered at maximum load.

9/10

Output Delivery

100W primary USB-C; multiport behavior and proprietary-protocol limits require attention.

9/10

Thermal Safety

Measured case temperature was 41.7–43.7°C at 100W, showing controlled thermal behavior.

8/10

Cell Quality

Pack make is not independently identified, but high-load efficiency and temperatures are strong.

9/10

Portability

428g and roughly one inch thick; unusually compact for a cable-equipped 20,000mAh bank.

8/10

Recharge Speed

65W-class input; roughly two hours to full in testing.

9/10

Build Practicality

Dual integrated cables and excellent color telemetry; lacks useful high-power pass-through.

IDEAL FOR

·Work travel
·100W ultrabooks
·Students
·Cable-free daily bags

NOT FOR

·Pass-through charging setups
·Continuous 100W loads to empty

DESIGN & ERGONOMICS

Slim, grippy and professional-looking. Dual built-in cables remove clutter, while the color screen clearly shows percentage and live watts. No real pass-through is the main UX omission.
