Powering a laptop
Most power banks cap out around 20W to 30W, which is phone territory. Flash Pro Ultra delivers 140W over USB-C, which is the rate a 16 inch MacBook Pro charges at. It runs a laptop at full speed rather than slowly topping it up.
Capacity is 25,000mAh, or 90.75 watt-hours. That matters more than the mAh figure, because airlines cap carry-on batteries at 100Wh without special approval. Flash Pro Ultra sits under that line, so it flies.
| Laptop | Charges at | Full charges from one Flash Pro Ultra |
|---|---|---|
| MacBook Pro 16" | 140W | about 0.8 |
| MacBook Pro 14" | 96W | about 1.1 |
| MacBook Air 15" | 70W | about 1.2 |
| MacBook Air 13" | 35W | about 1.5 |
Those figures account for transfer losses, which is why they are lower than the raw arithmetic. A 16 inch MacBook Pro battery is 99.6Wh, almost exactly the airline ceiling, so no power bank you can legally fly with will fully recharge one. What 0.8 of a charge buys you is most of a second working day.
Laptop charging uses the USB-C cable. The magnetic pad is for phones.
Will this charge a MacBook Pro?
Yes. Flash Pro Ultra delivers 140W over USB-C, which is the full charging rate for a 16 inch MacBook Pro. Expect about 0.8 of a full charge from one bank, or about 1.1 charges for a 14 inch.
Can I take it on a plane?
Yes. At 90.75 watt-hours it is under the 100Wh airline carry-on limit, so no approval is needed. Most airlines allow two batteries under 100Wh per passenger, some only one.

Frequently Asked Questions
Is the Flash Pro Ultra safe for air travel?
Yes. The Flash Pro Ultra has a capacity of 25,000mAh, which is equivalent to 90.75Wh. This is under the 100Wh limit for lithium-ion batteries that can be carried onto commercial flights, making it fully carry-on compliant worldwide.
How many times can it charge my phone or laptop?
The Flash Pro Ultra holds 25,000mAh (90.75Wh). Accounting for the standard 85% energy conversion efficiency of all power banks, the usable output is approximately 21,250mAh. In real-world use, this translates to roughly 6 full charges of an iPhone 15 Pro, 4 full charges of a Samsung S24 Ultra, 1.9 full charges of an iPad Pro 12.9", or approximately 0.8 charges of a 16" MacBook Pro.
Can I charge multiple devices at once?
Yes. The Flash Pro Ultra can charge up to 6 devices simultaneously using its three USB-C ports, one USB-A port, and two built-in wireless chargers (one for your phone and one for your Apple or Samsung watch).
Will it fast-charge my MacBook Pro 16"?
Yes. The main USB-C1 port supports Power Delivery 3.1 and delivers up to 140W, which is the exact requirement for fast-charging a 16" MacBook Pro — from 0% to 50% in around 30 minutes.
What is the fastest way to recharge the power
For the fastest recharge, use a 140W USB-C wall charger and a 140W-rated USB-C cable. This will recharge the Flash Pro Ultra from 0% to 100% in approximately 70 minutes.
Is the wireless charger MagSafe compatible?
Yes. The main wireless charging pad is fully MagSafe compatible, providing a secure magnetic connection and delivering up to 15W of fast wireless charging to compatible iPhones.
Can I charge my Apple Watch or Samsung Watch?
Yes, but the variant matters. The Flash Pro Ultra comes in two versions — one with a built-in Apple Watch charger (5W) and one with a built-in Samsung Watch charger (3W). The main wireless charging pad on both variants supports all Qi and MagSafe-compatible devices. Make sure to select the correct variant for your watch when ordering.
What devices are compatible?
Any device that charges via USB-C, USB-A, or Qi wireless charging is compatible. This includes all models of MacBook, iPhone, iPad, Samsung Galaxy, Google Pixel, Apple Watch, Samsung Watch, Nintendo Switch, Steam Deck, and more.
Is it safe to use?
Yes. The Flash Pro Ultra is built with multiple layers of safety protection, including over-current, over-voltage, over-temperature, and short-circuit protection, ensuring all your devices are charged safely.
What's in the box?
The Flash Pro Ultra comes with the power bank itself and an instruction booklet. A USB-C charging cable and wall charger are not included and must be purchased separately.
