Charmast W1148 10,000mAh Power Bank with 4 Built-In Cables and Digital Display

Four built-in cables make this Charmast power bank easier to pack for a day out: you can charge compatible devices without bringing a separate cable for each one.

Its 10,000mAh capacity and six outputs let you charge up to six devices at once. A digital display shows the remaining charge so you can keep an eye on when the power bank needs recharging.

With three input options, including a built-in recharging cable and USB-C and Micro inputs, it offers practical flexibility for topping up the power bank. A travel pouch is included for carrying it with your everyday essentials.

Worth noting

The W1148 combines four built-in cables—three for output and one for recharging—with six total outputs. This makes it useful when several people or devices need a charge, or when you want to keep a phone, tablet and other electronics powered without packing a collection of charging leads. Its listed compatibility includes iPhone, Samsung Galaxy and Google Pixel phones, as well as select tablets, AirPods and Apple Watch Series devices. Check that the connector matches your device before use.

The digital display gives you a clear percentage for the remaining battery, making it easier to decide when to recharge rather than estimating from a basic indicator. The power bank can be recharged through its attached cable, USB-C input or Micro input. For USB-C recharging, the manufacturer describes an approximate 4.5-hour charge with a 15W-or-higher adapter and a separate suitable cable, using the attached recharging cable is described as taking around six hours with a 12W-or-higher adapter. A wall plug is not included. Buyers often highlight the convenience of the built-in cables and carrying it for travel or everyday use. Feedback on charging speed and weight is mixed, so experiences differ.

Who it’s for

This power bank suits people who carry more than one device, share charging with others or want to leave spare cables at home. It is also a practical fit for travel bags and daily commutes: the attached cables stay with the unit, while the pouch helps keep it together with other essentials. Compared with a basic power bank that relies on separate leads, the W1148 puts several charging connections in one portable unit.

Its 10,000mAh capacity gives you a portable reserve for compatible electronics, and the six outputs allow up to six devices to connect at once. That multi-device setup is especially handy during a trip when phones and accessories need charging around the same time. The manufacturer states it can be taken on a plane, follow the requirements that apply to your airline and itinerary.

Tips for day-to-day use

Check the remaining percentage on the display before heading out, then recharge the bank when needed using one of its three input options. For USB-C recharging, use a suitable separate cable and an adapter rated at 15W or above to match the manufacturer’s stated approximate 4.5-hour charging time. The attached recharging cable is another option when you want to avoid packing a separate cable for the power bank itself.

When charging several devices, connect each one to the output that matches its port. The built-in leads cover a range of common device connections, while the additional outputs offer more ways to connect. Keep the included pouch with your travel kit to make the power bank easy to carry between outings.

Should you buy it?

Choose the Charmast W1148 if your priority is carrying fewer separate cables while keeping multiple devices chargeable from one power bank. Its 10,000mAh capacity, digital charge display, three recharging inputs and ability to charge up to six devices at once make it well suited to shared charging, travel and everyday carry. The built-in connections are the defining convenience: more of what you need to charge stays together in one unit.
