Bequest Power Bank with 100W AC Outlet

31,200mAh is the headline number, but the more useful figure is the roughly 116Wh it converts to once cell voltage is factored in — Wh is what actually determines how much real device charging you get, since it accounts for voltage in a way a raw mAh number doesn't. At 116Wh, this unit can charge a 12-inch MacBook-class laptop roughly 1.8 times, an iPad Mini-sized tablet around 4 times, or a phone in the iPhone X/Galaxy S9 class 5 to 8 times, depending on the specific device's own battery size.

Worth setting expectations correctly: 116Wh is a genuinely useful travel capacity, but it's on the smaller side within the AC-output power bank category specifically, where 200Wh-plus units are common. This is the right amount of capacity for keeping a laptop and phone topped up over a day or two away from an outlet, not for running something continuously for hours.

The 100W AC outlet is the spec that matters most on this unit, since it sets a hard ceiling on what the wall-style socket can run. 100W comfortably covers most laptop chargers, camera battery chargers, drone battery chargers, and small fans or lights. It will not run anything genuinely power-hungry — a hairdryer, a space heater, a full-size kitchen appliance, or anything else that draws several hundred watts or more. Always check the wattage rating of whatever you intend to plug in against this 100W figure before buying; exceeding it will typically cause the unit to shut off automatically to protect itself rather than deliver reduced power.

The 12W USB-A port is a standard-speed port suited to phones and small accessories rather than fast charging; expect a meaningfully slower charge than a modern 20W-plus fast charger would deliver. The 15W USB-C port is faster and doubles as the port used to recharge the power bank itself, a common design choice on units in this price and capacity range that keeps the port count down without sacrificing a dedicated fast-charge port for USB-C devices. Neither port comes close to the 100W the AC outlet delivers, so USB ports on this unit are best treated as the option for phones and small accessories, with the AC outlet reserved for anything laptop-class or larger.

At approximately 2.4 lb, this sits in the middle weight range for a 100W-class AC power bank — noticeably heavier than a standard USB-only power bank of similar mAh, since the AC inverter hardware and larger cell add real weight, but still light enough to travel with rather than needing to be carried like a dedicated power station. It's built with a single AC outlet, a USB-A port, and a USB-C port, without the OLED displays, solar input, or multiple AC sockets found on pricier units in this broader category.

Bequest lists this unit as compatible with a broad range of laptops, phones, cameras, drones, and fans. In practice, "compatible" for the AC outlet means any device that plugs into a standard wall socket and draws under 100W; the AC outlet doesn't care what kind of device it is, only how much power it needs. For USB-charged devices, standard USB-A and USB-C cables work as they would with any wall charger, though charging speed will match this unit's 12W and 15W ceilings rather than whatever faster charger the device might otherwise support.

Within the AC-output power bank category, this unit sits at the entry-to-mid tier by both capacity (116Wh) and AC wattage (100W). Larger units in this category commonly reach 200 to 300Wh with AC output in the 150 to 300W range, better suited to running multiple devices or slightly more demanding equipment, at a real increase in both price and weight. Against a standard USB-only power bank of similar mAh, the defining trade-off is the same one that applies to this whole category: the AC outlet adds real capability (anything with a normal wall plug) at the cost of extra weight and a lower effective USB-only capacity than a dedicated USB power bank of the same physical size would offer.

Travelers and business trip use. A laptop charger, phone charger, and one AC-outlet device covered from a single unit light enough to pack.

Drone and camera hobbyists needing field charging. The AC outlet covers charger bricks that don't have a USB or car-charging option.

Light outdoor use — camping, tailgating, small power needs. Enough capacity for a fan, light, or small device over a day.

Not for home backup during outages. 116Wh will not run a router, fridge, or medical equipment for any meaningful stretch; a dedicated portable power station with several hundred Wh is the right category for that.

Not for anyone needing to run multiple AC devices at once. One AC outlet, one device at a time, up to 100W total.
