Promate SolarTank-10PDQi
10,000mAh · ≈37Wh estimated · 20W fastest USB-C port · 1.21W solar. Confirm the exact model, USB protocol, cable and delivery terms before ordering.
Capacity
10,000mAh nominal; 37Wh rated energy (an estimate, because the maker publishes mAh rather than rated Wh).
Output
Up to 20W from one USB-C port; 20W combined output; USB-C + 2× USB-A + 10W wireless; built-in cable: no.
Integrated solar
Integrated integrated panel rated 1.21W; manufacturer refill guidance: 50 hours in the manufacturer's specification. Treat the panel as slow replenishment, not a fast refill.
Practical caution
The published 50-hour solar charge time makes this an emergency panel, not a reliable same-day refill source.

Buying checks for the United Kingdom
Single-port output: Use the fastest single USB-C port and its supported charging profiles—not the larger combined multi-port marketing figure. Cable and charger: Confirm the included cable rating and whether a wall charger is supplied. A 100W power bank cannot deliver 100W through a lower-rated cable. Comparable capacity: Compare watt-hours as well as mAh. Published mAh normally refers to internal cell voltage, while real device charging also loses energy in conversion. Travel and warranty: Check the airline's current battery rules, the exact model label and whether local warranty support applies to an imported unit.
Regional note
Confirm the exact model, USB protocol, cable and delivery terms before ordering.
