Compare our laptop power banks

Both portable chargers hold 25,000mAh and stay under the commonly used 100Wh airline limit. The difference is how fast each one charges a laptop, and what it charges wirelessly.

Power bank	Best for	Capacity	Total output	Strongest USB-C port	Wireless charging	Weight
Flash Pro Ultra	A 16-inch MacBook Pro, or a laptop plus phone, tablet and watch	25,000mAh / 90.75Wh	275W	140W PD 3.1 on USB-C1	Qi2 15W, Apple Watch 5W, Samsung Galaxy Watch 3W	590g
Flash Pro Plus	A 14-inch MacBook Pro, MacBook Air or Windows ultrabook	25,000mAh / 92.5Wh	190W	100W PD 3.0 on USB-C1	Magnetic 15W, Apple Watch 5W	583.5g

Both charge up to six devices at once, and both support pass-through charging, so one wall outlet can recharge the power bank and run your devices at the same time. The ports share the total output, and each product page shows the exact split for every combination.

Can I take a power bank on a plane?

Heading

Usually yes, in your carry-on. Most airlines follow the same rule: spare lithium batteries up to 100Wh are allowed in the cabin and must not go in checked baggage.

Watt-hours are what matters, not mAh. Flash Pro Ultra is 90.75Wh and Flash Pro Plus is 92.5Wh, both under that threshold, and the figure is printed on each one.

Rules differ between airlines and change, and several carriers have tightened how power banks may be used in the cabin. Check your airline's current requirements before you fly.
