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

HAMA Colour 20 is an external battery with a capacity of 20000 mAh, aimed at the practical mid-range level – it is not pocket-sized mini, but it gives you a serious reserve of energy for your phone, headphones, and other gadgets. It relies on a Li-Polymer cell and combines USB and USB-C outputs, so you can charge both newer and older devices. Weighing 361 g, it is more suitable for a backpack or bag than for a tight pocket, but in return, you get many charge cycles away from the outlet. The green color gives it a slightly different look from classic black power banks.

What you get

With a capacity of 20000 mAh, you can charge a typical smartphone several times before the battery itself runs out, which is convenient for weekend trips, festivals, or business trips. The output current of up to 3 A allows for stable and relatively fast charging of compatible devices without “choking” them with low current. Thanks to the two outputs – USB-C and standard USB – you can power two phones or a phone plus an accessory simultaneously without worrying about which cable to plug where. The Li-Polymer technology helps achieve a better balance between capacity, weight, and form, so the battery remains relatively compact for a 20,000 mAh class.

• Capacity of 20000 mAh, sufficient for several full charges of a typical smartphone while on the go.
• Maximum output current of 3 A, providing stable and faster charging compared to low-amp power banks.
• Two output connections – USB and USB-C, allowing you to charge two different types of devices simultaneously.
• Battery with Li-Polymer technology, allowing for a thinner and more convenient form factor for carrying.
• Weight of 361 g, suitable for a backpack or bag when you need a large energy reserve.
• Green color, which stands out from typical black or gray external batteries and is easier to find in a backpack.
• 24 months warranty, giving you peace of mind for a longer usage period.

Who it is suitable for

This model is suitable if you travel often, use navigation, take a lot of photos, or simply don’t want to think about charging during the day – especially if you have more than one device. It is also convenient for people who charge their friends' or colleagues' phones and gadgets – the two outputs make it a practical “shared” power bank. If you are looking for something ultra-light and super compact for small bags or pockets, here the capacity comes at the cost of a bit more weight.

The most sensible combination here is the large 20000 mAh capacity, the two outputs (USB and USB-C), and 3 A output current – you get a reliable source of energy for almost any situation without unnecessary complications.
