Detailed overview: Voltcraft VC-GP40 144000 mAh power bank
The Voltcraft VC-GP40 is an outsized power bank that sits on the border between a power bank and a portable power station. With a capacity of 144000 mAh, or about 460 Wh, it offers a reserve of energy far beyond a conventional power bank, while keeping a format you can still carry thanks to its handle and carry bag.
Its central asset is the LiFePO4 (lithium iron phosphate) chemistry of its cells. More thermally stable and far more durable than standard lithium-ion, it withstands a large number of charge cycles and offers enhanced protection against overheating, a real plus for a device meant for camping, converted vans or home backup.
On connectivity, the VC-GP40 is very complete: two USB-C ports delivering up to 100 W over Power Delivery 3.0, enough to charge a laptop at full speed, two USB-A ports, two 12 V cigarette-lighter sockets and a Large Anderson output able to power devices up to 300 W. A warm-white LED light rounds things off for extra lighting or emergencies.
Recharging is done from the mains with the supplied adapter (12 to 24 V input, 100 W max), or via a 100 W solar panel connected to the DC input, which makes it self-sufficient far from any outlet. A status display shows the charge level in real time.
Its only real limits are its weight, close to 4.6 kg, which makes it better for semi-nomadic use than a backpack, and the lack of a 230 V mains socket: unlike a true power station, it has no inverter to plug a device straight into the mains. To power devices over USB, 12 V or Anderson with a huge reserve of energy, it remains a rugged and versatile solution.

Comparison
Where does the Voltcraft VC-GP40 sit between a large power bank and a small power station?
| Criterion | Voltcraft VC-GP40 | Anker 548 (60000 mAh) | EcoFlow River 3 |
|---|---|---|---|
| Capacity | 144000 mAh (~460 Wh) | 60000 mAh (192 Wh) | 245 Wh |
| 230 V mains socket | No | No | Yes |
| Max output | 300 W (Anderson) | 60 W (USB-C) | 300 W (AC) |
| Chemistry | LiFePO4 | Li-ion | LiFePO4 |
The VC-GP40 offers a capacity well above the largest power banks on the market, with the longevity of LiFePO4, but no 230 V mains socket. Against a small station like the River 3, it stores far more energy and often costs less, at the price of having no AC inverter and a higher weight. It is the right compromise for anyone powering mainly USB, 12 V or DC devices.
Our tester's review: Guillaume Hoarau
The Voltcraft VC-GP40 plays in a category of its own: not quite a power bank, not quite a power station. In use, what strikes you first is its huge reserve, 144000 mAh of LiFePO4 that last several days while camping. We used it to charge a laptop at full speed over the 100 W USB-C port, run a small fan from the 12 V socket and keep two smartphones topped up all weekend without it flinching. The 300 W Anderson output opens the door to more demanding devices, provided you have the right cable. The LiFePO4 chemistry is reassuring on lifespan and safety, and the built-in LED light genuinely comes in handy at night. The two real downsides are the weight, close to 4.6 kg, which makes it better suited to a van, a fixed campsite or home backup than a backpack, and the lack of a 230 V mains socket: everything runs through USB, 12 V or Anderson. But for anyone after a big, rugged energy reserve without paying the price of a full power station, it is a clever proposition.
Frequently asked questions: Voltcraft VC-GP40 144000 mAh power bank
It is a hybrid. With 144000 mAh (about 460 Wh) it has the reserve of a small station, but it delivers its energy over USB, 12 V and Anderson, with no 230 V mains socket or inverter.
Yes, at full speed. Its two USB-C ports deliver up to 100 W over Power Delivery 3.0, enough for most laptops, while keeping a huge reserve for several days.
Yes. Its DC input accepts a solar panel of up to 100 W, which makes it self-sufficient while camping or in a van, far from any power outlet.
No. At about 460 Wh, it is far above the 100 Wh cabin limit set by airlines. It cannot be carried on a plane, unlike small power banks.
