Charmast Power Bank with Built-in Cables (x4) 10000mAh, USB-C Portable Charger with 6 Outputs & 3 Inputs

If you’re tired of untangling cables every time you need to top up your phone, this Charmast 10000mAh power bank is built around a simple idea: built-in charging cables, so you can plug in and go. It also leans into convenience and capacity for everyday use rather than trying to be a full-on replacement for wall chargers.

That said, it’s not a perfect fit for everyone. The built-in cable approach is handy, but it can be less flexible if you prefer to use your own cables, or if your devices only charge with very specific setups. Worth weighing up before you buy.

Quick overview

The Charmast power bank comes with built-in charging cables (four integrated cables), aiming to remove the usual faff of carrying spares. On top of that, it supports multiple devices thanks to 6 outputs, while offering 3 input options to recharge the battery pack itself.

The battery capacity is listed as 10000mAh, and it includes an LED display intended to show battery level from 0% to 100% so you’re not guessing how much charge you’ve got left.

In daily terms, this positions it as a practical portable charger for commuting, days out, travel between meetings, or keeping tablets and smartphones topped up when you’re away from a socket.

Key features that matter day to day

Where this power bank stands out is the “no cable mess” design. With built-in cables, you don’t need to hunt for a matching lead or pack multiple items—handy if you’ve ever left a cable behind and regretted it.

The multi-output claim (6 outputs) suggests it’s designed for households or shared moments—think charging multiple phones, or a phone plus another small device—without needing a separate adapter each time.

The LED display is another small-but-useful touch. Instead of relying purely on an indicator light, it’s intended to show the charging progress so you can plan when to recharge the power bank.

There’s also the portability angle: it’s listed at 144.34 x 66.9 x 17.7 mm and 240 g, so it should sit comfortably in a bag without becoming dead weight.

Performance expectations (and where it may feel limited)

Capacity-wise, the entry provides example charging figures for common models. On paper, that helps set expectations: it suggests it can recharge iPhone 11 around 2 times, iPhone 12 around 2,3 times, and Samsung S21 around 1,5 times.

Those numbers are useful, but it also means you shouldn’t assume it’ll feel identical across all devices and scenarios. Real-world charging can vary depending on the device’s power draw, how many outputs you’re using at once, and cable/charging conditions. If you’re planning to run several devices simultaneously for a long time, you may find you need to recharge the power bank sooner than you hoped.

Who it suits (and who should look elsewhere)

It makes sense if you want a power bank for everyday life—commutes, shopping trips, holidays, and the “I’m out and my phone’s at 10%” moments—especially if you prefer the idea of built-in cables.

It’s also a good match if you often travel with more than one device and like the thought of multiple outputs in one pack.

It might not be the best choice if you already have a strong set of cables and want maximum flexibility, or if you’d rather keep everything standardised with your own leads. Also, if you only need one or two charges and you’re primarily chasing the lightest option, this one may feel a bit more “feature-heavy” than you actually need.

Getting the most from it

A practical way to use this: arrive at work with the power bank in your bag, connect one device using the built-in cable when you first see the battery dip, then top up again later in the evening before heading home. For a day trip, it’s also sensible to keep the LED display in mind—charging the power bank when it’s not fully depleted can help you avoid the awkward “dead pack” situation.

Is it worth it?

Buy it if you value convenience: built-in charging cables (x4), a 10000mAh capacity that’s positioned for multiple daily top-ups, and an LED display to track charge from 0% to 100%. The multi-output design is particularly appealing if you regularly charge more than one device.

Skip it if you prefer using your own cables, need ultra-minimal portability, or you know you’ll often rely on charging several devices at the same time for extended periods—capacity can only stretch so far, and real-world performance may vary.

If you’re trying to decide between a basic portable charger and something more “ready out of the box”, this Charmast leans clearly towards the second option.
