Strengths, weaknesses and who each model is really suited to.
The only power bank in the 24,000 mAh class with a genuine 140 W PD 3.1: charges a MacBook Pro 16" at full speed. OLED display shows remaining capacity, battery health and live watts per port. Airline-approved (86.4 Wh).
30% more compact than typical 100 W power banks. Digital display, fully charged in 84 minutes. 3 years of warranty. One of the best value-for-money options for laptop users on the move.
Ultra-flat (14 mm), fits in trouser and jacket pockets. Charges 4 devices at once, but only 15 W maximum output (no PD). Perfect for smartphone/headphones/smartwatch, not for a laptop.
Torn between two specific models? Here is the direct comparison:
One with USB-C Power Delivery (PD) from about 60 W and 20,000 mAh upwards. For larger laptops, 100 W makes sense. Important: the USB-C port must also deliver the full power, not just take it in.
Up to 100 Wh in hand luggage without approval, which covers almost all models up to about 27,000 mAh. Conversion: Wh = (mAh ÷ 1000) × 3.7. Power banks must never go in checked luggage.
In practice about 3 to 4 full smartphone charges, not the calculated 4 to 5 because of conversion losses. For a laptop it usually gives one partial charge or a few hours of extra runtime.
