Modern life runs on battery power, and there are few things more frustrating than watching your phone die when you're away from a socket. The CUKTECH CP24 20000mAh 40W Power Bank was built to solve that problem completely.

Whether you're traveling across Ireland, working remotely, attending a festival, or simply someone whose phone never seems to make it through the day, the CP24 gives you the freedom to stay connected without ever hunting for a plug socket.
What sets the CP24 apart from cheaper alternatives is the combination of capacity and charging speed. At 40W output, it charges compatible smartphones dramatically faster than standard 5W or 10W power banks that have flooded the market.

The CP24 is also built for the purpose of multiple devices being charged at once. By having multiple output ports, one can easily charge a phone, two wireless earphones, and a smartwatch at the same time effortlessly. The battery itself charges fast, so there is no need to keep it plugged in all night long. The build quality is solid and premium-feeling, with a design that looks and feels expensive without the price tag to match. It's the kind of power bank you're proud to pull out in public rather than hide away in your bag.

Frequently Asked Questions
The capacity of the CP24 is 20,000 mAh; thus, you should expect four to six charges using the CUKTECH CP24 depending on your smartphone. For instance, if you use the CUKTECH CP24 to charge your iPhone 15 that has 3,877 mAh of battery, you can fully charge it five times. This applies as well when charging a Samsung Galaxy S24 of 4,000 mAh battery capacity.
It feels dramatically faster than you're probably used to if you've been using a standard 5W or 10W power bank. With a compatible 40W cable and device, you'll see your phone battery climb noticeably quickly — similar to the speed you'd experience from a quality wall charger. For compatible devices, going from nearly empty to a usable charge takes a matter of minutes rather than the frustrating half-hour wait of slower power banks.
The inbuilt USB-C and Lightning cables are meant for quick charging at the CP24's output speed, unlike most power banks where the inbuilt cables charge only at the lower 5W trickle speed. This is vital since most power banks with inbuilt cables do not support the power bank's output speed. In other words, the inbuilt cables on the CP24 will be able to charge at the full output speed that the CP24 supports.
Yes, as CP24 offers multiple outputs, it becomes easy to charge several devices simultaneously. A mobile can be charged with the built-in cables, whereas another device can be charged with the help of a USB-A port, while wireless earbuds can be charged through another port.
Depending on the type of charger that you will be using for topping up the CP24, you may experience faster charging compared to the standard 5W or 10W charger. For instance, if you use a high-wattage USB-C wall charger, it will take only 3 to 4 hours to recharge the 20,000mAh capacity of the CP24 using a 45W charger.
Power banks such as the CP24 are allowable on-board as carry-ons in accordance with IATA regulations. The CP24 with a 20,000mAh battery capacity and 3.7V nominal voltage produces about 74Wh of energy, which is less than the standard limit of 100Wh per lithium battery for airline carry-ons.
The CP24 is a wired charging power bank, and wireless charging is not possible. There is no use of a wireless charging pad, and all charging is done through wired ports and cables. If you need wireless charging in a power bank, then the CUKTECH CP132ML Magnetic Power Bank is the right option for you.
The CP24 uses intelligent Power Delivery protocols that detect the requirement of charging speed by the device. If your device supports 40W or higher fast charging, it will charge at or near that speed. If your device only supports 18W or 25W fast charging, the CP24 will adjust to deliver at that speed safely. It will never push more power than a device is designed to handle.
The CP24 has a built-in digital LED display screen that shows the remaining percentage of battery capacity. Contrary to other lower-quality batteries, which have four-dot LEDs, the percentage indicator in the CP24 gives a clear indication of how much capacity is left in the battery.
Yes. The CP24 has several built-in safety features, including overcharge protection, short circuit protection, over-temperature protection, and shut down if there is no load connected. These features ensure that the battery remains safe all the time. In addition, the built-in cables have a feature to retract or store to avoid any accidental activation.
There is quite some difference. In most cases, an affordable 20,000mAh power bank utilizes inferior-quality battery cells that do not deliver the required capacity, have very low charge speeds of 10W or 15W, have no inbuilt cables, and have few safety features. The CP24 delivers 40W real-world fast charging, genuinely useful built-in cables, proper safety circuitry, and quality battery cells that deliver the rated capacity reliably over hundreds of charge cycles.
Even for home-based users, a quality power bank like the CP24 adds genuine value. It's ideal for charging devices away from wall sockets — in the garden, in bed, on the sofa, or during power outages. It's also invaluable for travel, days out, and emergencies. The CP24's build quality and performance mean it's a purchase that earns its place in your life whether you travel constantly or almost never.
