Portable Charger 56,800mAh

When you’re away from an outlet for more than a day, a small everyday power bank may not keep up. This 56,800mAh portable charger is designed to provide backup power for longer trips and outages.

It can charge up to three devices at once through two USB-A outputs and a two-way USB-C port. The LED display shows the remaining battery percentage.

That capacity comes with a practical catch: the listing says this charger is not allowed on airplanes.

Best use cases

This power bank is aimed at camping, road trips, outdoor work, and emergency kits—situations where charging opportunities may be limited. For example, you could keep it in a gear bag on a camping trip and use it to top up a phone, earbuds, and a tablet without taking turns at an outlet.

It’s a great fit if you need several days of backup power for USB devices and don’t mind carrying a high-capacity battery. From the way it is set up, it prioritizes extended backup and charging several devices over being an airline-friendly travel companion. If most of your trips involve flying, its stated restriction is a dealbreaker to factor in before choosing it.

Product specs

The stated capacity is 56,800mAh, with up to 22.5W USB-C fast charging. The product description says it can charge an iPhone 17 to about 60% in around 40 minutes, and claims 10 or more charges for an iPhone 17 or Galaxy S25. Those are listing estimates, not a guarantee for every device or charging situation.

Two USB-A outputs and one two-way USB-C port allow up to three devices to charge at once. The display shows the remaining charge as a percentage, while stated safeguards cover overvoltage, overheating, short circuits, and overcurrent. You’ll need your own USB charging cables. The listed compatibility includes iPhone 13–18 series, Samsung Galaxy S23–S25, Google Pixel 7–9, iPads, tablets, earbuds, and other USB devices, check that your device uses a compatible cable and charging connection.

Where it shines

The main appeal is having a substantial reserve available when several devices need power and outlets are scarce. On a road trip, for instance, a passenger could charge a phone while another device uses the second output, then check the display before heading out again. That’s a different buying approach from choosing a smaller, lower-capacity charger for occasional phone top-ups: this model favors longer backup and multiple devices, with the tradeoff of its explicit no-airplane restriction.

The capacity and charging-time figures are manufacturer claims, and actual results can vary with the device and how it is used. The description also mentions a three-year MaiVoz Care replacement policy for quality-related issues, but doesn’t give further terms here.

Buying verdict

Choose this charger if your priority is keeping multiple USB devices running during camping, road travel, outdoor work, or a power outage, and you can leave it out of air travel. Its percentage display makes it easier to judge how much reserve remains, while the three outputs reduce the need to charge devices one at a time.

Better avoided if you need a power bank you can take on a flight, or if your main goal is a simple charger for occasional, light use. In those cases, a lower-capacity option without this stated restriction may suit your plans better. The deciding question is whether you’ll use the extended backup enough to justify a charger that cannot go on a plane.
