Laptop Power Banks

Three USB-C laptop power banks built for real wattage, real workloads, and carry-on compliance on every airline.

Finding a power bank that actually charges a laptop comes down to output wattage, not the mAh figure on the box. A large mAh number means nothing if the power bank cannot match what the laptop draws under real conditions. GRAVL's laptop power bank collection exists for exactly that gap: three power banks engineered to deliver meaningful wattage to real laptops, each sized for a different workload, all airline compliant, all covered by the same 4-year warranty.

The Three Products

GRAVL Axis 67

The GRAVL Axis 67 is the single-device option. At 20,000mAh with a 67W USB-C output, it is right-sized for a MacBook Air M2 or M3, ultrabooks, and similar light-to-moderate workloads. The wattage matches what these laptops actually draw extra output does not charge a laptop faster than it can accept. The Axis 67 is the most compact of the three, built for the bag that goes everywhere.

GRAVL Forge 130

The GRAVL Forge 130 is built for two devices at once. It carries 20,000mAh and outputs 130W total 65W through its USB-C port and 65W through its built-in cable, both simultaneously. That is what dual-device charging means: not one output shared between two ports, but two independent full-speed outputs running at the same time. The right choice for a MacBook Pro 14-inch running alongside a phone.

GRAVL Engine 240

The GRAVL Engine 240 is the high-draw option. At 27,000mAh and 97.2Wh 2.8Wh under the IATA 100Wh airline ceiling it is the highest-capacity power bank in India that still flies without prior approval. Its 240W total output runs 140W through the built-in cable and 100W through the USB-C port simultaneously. That covers a MacBook Pro 16-inch M4 Max at full load while a second device charges at full speed, and extends to high-draw Windows machines including the Dell XPS, ASUS ROG, and HP Spectre.

Airline Compliance

Every power bank in this collection sits within IATA's 100Wh carry-on limit. None require prior airline approval. All three print the Wh rating on the unit nothing to calculate at the gate.

Warranty

Every product carries GRAVL's 4-year warranty: 1 year unconditional from purchase, plus 3 years on the battery with product registration. The same terms apply across all three models.

Choosing Between the Three

For a MacBook Air on a single-device workload, the Axis 67 is correctly sized. For a MacBook Pro 14-inch and a phone charging simultaneously, the Forge 130's 65W + 65W split is the right fit. For a MacBook Pro 16-inch M4 Max, or any high-draw Windows laptop, the Engine 240 is the only option with sufficient output. All three carry identical warranty terms the decision should be on wattage and workload.
