HAMA External Battery "Colour 20", 20000 mAh, 2 outputs: USB-C, USB-A, dark red

HAMA Colour 20 is an external battery with a capacity of 20000 mAh, aimed at people who want peace of mind that their phone or other devices won't run out of charge during the day – or for several days. The model is rather in the mid-high range of power banks due to its capacity and combined connectivity via USB and USB-C. The dark red casing makes it different from typical black bricks, and the weight of 361 g is a reasonable compromise for the capacity. The emphasis here is on practicality: a large energy reserve, universal compatibility, and clear orientation towards daily use.

What you get

With a capacity of 20000 mAh, you can charge a modern smartphone several times before the battery itself needs a wall outlet. If you carry a second device – for example, wireless headphones or a second phone – the two outputs USB and USB-C allow you to charge them simultaneously without fighting for a single port. The output current of up to 3 A provides stable and fast charging for most phones and small devices, without torturing them with slow current. The lithium-polymer (Li-Polymer) technology helps the battery remain more compact and perform better over longer usage cycles. The warranty of 24 months gives you peace of mind that if something goes wrong, you won't be left alone with the problem.

• Large capacity of 20000 mAh, sufficient for several full charges of a standard smartphone or a combination of several smaller devices.
• Two outputs – USB and USB-C, allowing you to charge different devices simultaneously without the need for adapters.
• Maximum output current of 3 A, providing faster and more stable charging compared to weaker power banks.
• A Li-Polymer battery is used, allowing for a flatter and more compact design and more predictable behavior during daily use.
• Universal compatibility with phones and other devices thanks to USB and USB-C connectivity and the attribute “Universal”.
• Weight of 361 g, a reasonable balance between portability and high capacity for longer days outdoors or travel.
• 24 months warranty, which is important for a device you will carry every day and subject to regular load.

Who it is suitable for

This external battery is for you if you are often on the go, traveling, gaming, and streaming from your phone, or carrying more than one device that needs charging during the day. It is also suitable for people who want “plug and forget” without worrying whether the power bank will last a weekend outdoors. If you are looking for something ultra-light for your pocket and use a power bank rather sporadically, you might consider a smaller capacity.

The combination of 20000 mAh, dual output USB/USB-C, and 3 A output current makes HAMA Colour 20 a stable and practical choice if you need a reliable energy reserve every day, not just an emergency solution.
