Can a power bank actually charge a laptop, or does it just top it up?
It depends on the output, not the mAh figure. A power bank only charges a laptop properly if its wattage meets or exceeds what the laptop draws while in use. GRAVL's laptop power banks are built around this: the Axis 67 outputs 67W, the Forge 130 outputs 130W total (65W + 65W simultaneously), and the Engine 240 outputs 240W total (140W + 100W simultaneously).
Which GRAVL power bank works with my MacBook?
The Axis 67 is sized for a MacBook Air M2 or M3 and similar ultrabooks. The Forge 130 is built for a MacBook Pro 14-inch, especially when a phone needs to charge at the same time. The Engine 240 is built for a MacBook Pro 16-inch M4 Max running at full load, and also covers high-performance Windows laptops like the Dell XPS, ASUS ROG, and HP Spectre.
Arethese laptop power banks allowed on flights in India?
Yes. All three the Axis 67, Forge 130, and Engine 240 stay within IATA's 100Wh carry-on limit, so none require prior airline approval. The Engine 240 sits at 97.2Wh, just 2.8Wh under that ceiling, making it the
highest-capacity airline-compliant option in the collection. Full rules at Airline Rules for Laptop Power Banks.
Can I charge my laptop and phone from the same power bankat the same time?
Yes, iPhone 12 or newer. The GRAVL Qi Surface power bank delivers 25W wireless charging on iPhone 16 and 17. Faster than Apple's own MagSafe on older models. If wireless has ever frustrated you, this is the version that doesn't.
Whatis the warranty on GRAVL's laptop power banks?
Every laptop power bank in this collection carries a 4-year warranty: 1 year unconditional from the date of purchase, plus an additional 3 years on the
battery once the product is registered. Both parts of the warranty apply regardless of which model
is purchased.
