Beschreibung
A power bank earns its reputation at the worst possible moment. The phone sits at nine percent, the trailhead is four hours behind, and the last ferry is already loading. Capacity numbers printed on a box say nothing about that moment. What matters is how much energy survives the conversion, how quickly it moves, and whether the pack still works after a season inside a rucksack.
The Reserve carries 50,000mAh of lithium polymer and pushes it out along a 66W Power Delivery path. That is enough to take a modern laptop from flat to working in a little under two hours, and to refill a phone four or five times without a wall socket in sight. USB-C and USB-A outputs run at the same time, so a camera, a headlamp and a phone can share the pack instead of queuing for it.
Build quality is where camping packs usually fall apart. This one runs an aluminium reinforced shell with recessed ports, an integrated UK plug that charges the pack straight from a wall socket without a separate adapter, and a charge readout that shows a number rather than a single blinking dot. Cold mornings, dusty tent floors and the inside of a toolbox are part of the design brief here, not an afterthought.
It is heavy by phone standards, close to the weight of a full one litre bottle, and that is the honest trade for a week of off-grid power. Carry it on foot and you should plan the route with that weight in mind. Leave it in a van, a cabin, a boat or a festival tent and the weight stops being a question at all.
Power on a trip is a logistics problem. This solves the logistics and lets you stop watching the battery icon.

Where It Earns Its Place
This is the pack that lives in places without sockets. Van conversions and camper builds use it to run a laptop, a router and two phones overnight. Festival goers carry it for a weekend when the charging tent queue is forty minutes long. Photographers working outside keep it in the case to top up camera batteries and a monitor between locations. Households in storm season keep one charged in a drawer so a two day power cut turns into an inconvenience instead of a blackout.
Frequently Asked Questions
Q: Can I take this on a plane?
A: Most airlines cap lithium batteries at 100Wh per pack, and this unit stores roughly 185Wh. That puts it outside the carry-on allowance of nearly every commercial carrier, and it must not go into checked baggage. Treat it as ground, sea and vehicle power.
Q: How many times will it charge a phone?
A: A typical 4,500mAh phone takes four to five full charges. Laptops draw far more, so expect one full charge for a 13 inch ultrabook and around half that for a larger workstation class machine.
Q: Does the UK plug work abroad?
A: The plug body is UK format. In Europe, North America or Asia you will need a travel adapter on the wall side, or you can charge the pack from any USB-C PD charger rated 45W or above through the input port.
Q: How long does the pack take to recharge?
A: From empty, roughly six to seven hours on a 30W wall charger and about four hours on a 65W USB-C PD supply. Charging overnight before a trip is the practical habit.
Q: Will it charge while it is being charged?
A: Yes, pass-through charging is supported, so the pack can sit on the wall and feed a phone at the same time. Expect a slower phone charge in that mode because the input and output share the same power path.
Q: What happens in cold weather?
A: Lithium polymer loses capacity below freezing, as all lithium chemistry does. Keep the pack inside your sleeping bag or jacket on sub-zero nights and usable capacity returns to normal once it warms up.
