Charmast Power Bank 22.5W (20,000mAh) with Built-in 4 Cables, 6 Outputs & 4 Inputs – Pink
Product description
If you’re the sort of person who always ends up rummaging for “the right cable”, this Charmast power bank is built around one idea: you don’t want to carry a pocket full of leads. The 22.5W portable charger comes with built-in multi-interface cables, plus multiple output options so you can keep more than one device ticking when you’re out and about.
That said, it’s not a magic fix for every charging need. It should cover typical phone and accessory charging situations well, but if you’re picky about charging speed for a particular device, it’s worth checking that your setup matches what the power bank is designed to do.
Key points
This model focuses on convenience first. With built-in cables (instead of relying on separate USB leads), it’s designed to remove that small daily hassle—especially when you’re travelling light or you’ve forgotten a cable at home. With a 20,000mAh battery capacity and multiple ports, it’s aimed at people who genuinely use their phone and other gadgets throughout the day.

The included LED display also helps with the “how much battery is left?” guessing game. On paper, it makes the power bank easier to manage, particularly if you’re planning a day out and want to know when it’s time to recharge.
What to know before buying
Built-in cables are brilliant for avoiding cable clutter, but there’s a trade-off: you’re committing to the interfaces included on the power bank. Charmast lists multiple multi-interface cables and mentions Micro USB/USB C/iPhone+USB-A among the built-in options, which should suit a mix of devices. Still, if your primary device uses a very specific charging standard you rely on, it’s worth double-checking your own cable/charging habits before you assume it’ll match perfectly.


Another practical consideration is how “simultaneous charging” behaves. The product description states it can charge multiple devices at once with 6 outputs and 4 input ways, which sounds flexible. In real-world use, charging speed can vary when you split power across devices, so don’t expect every connected gadget to charge at the same peak rate.

Where it shines (and what you’ll notice)
The main “you’ll notice this” feature is the built-in cable system. In use, it’s the kind of power bank you grab when you’re heading out for the day: one unit in your bag, then you plug in your phone via the built-in lead that fits. No adapters, no searching for that one cable that’s gone missing.
The second is the battery capacity and multi-output approach. If you’ve got a phone plus something like a pair of AirPods, smart accessories, or another mobile device, this is designed to handle more than one charge session without you needing to keep swapping power sources.

Who it’s for (and who should skip it)


It makes sense if you want a single power bank for daily travel where convenience matters—commuting, day trips, evenings out, and trips where cable management is more annoying than you’d like. The built-in cable approach also suits households where different devices get charged at the same time.
It may not be the best choice if you already have a well-organised set of charging cables you trust, because built-in leads can be less appealing if you prefer replacing cables individually when something wears out. Also, if you only ever need to charge one device and you’re chasing the absolute fastest performance possible per device, this may feel more like a practical mid-range convenience pick than a specialist speed tool.

Buying verdict
A solid pick if you want a portable charger with built-in cables, multiple outputs, and enough capacity for several days of typical phone use—especially when you’re juggling more than one device.
You may want to avoid it if you’re very particular about the exact cable/charging interface you need, or if you prefer using your own charging leads for every device. As always, it’s worth checking your device charging requirements against the interfaces mentioned (Micro USB/USB C/iPhone+USB-A) and thinking about whether you’ll regularly charge several gadgets at once.
