Green Cell PowerPlay 20 20000 mAh Powerbank

I’ve been using it for 3 years, mainly during multi-day outdoor trips. It’s neither too big nor too heavy. It charges quite fast. The price-to-quality ratio is very good. The 20,000 mAh capacity is enough for travel without fear of running out of power.

The power bank works very well, has a lot of different ports—it charges quite quickly and is useful both in everyday use and during outdoor trips for powering the most important devices. Very fast shipping, product well protected against damage. I recommend it.

The power bank does its job, though it takes a while to fully charge, it lasts a very long time. One power bank is enough for 2–3 days of charging a phone, another device, or even a flashlight.

Great product. Twenty thousand mAh for this price is fantastic. It charges very quickly and looks stylish. The included charging cable is a plus. It’s light and fairly small. A case would be useful, but I’m sure I’ll find something on militaria.pl.

Solid product. It is possible to simultaneously charge two devices and the power bank itself at the same time. A plus is the fast energy delivery, at a rate similar to a 20W wall charger. It does not slow down, and charging does not drag on for hours. The casing looks sturdy, the product is not heavy, and the included cable is good quality, so there’s no need to replace it right after buying. After the first charge, it lay unused for a month and I didn’t notice it self-discharging. I recommend it, it’s a really useful thing.

The power bank is solid, lightweight, and compact. The capacity matches what's listed in the description. It charges quickly. You can charge the power bank and other connected devices at the same time. I am very satisfied, I recommend it.

I confirm the product description, I agree with all the information. The device is equipped with high-class electronics that monitor the temperature of the Li-Po cells and protect against short circuits and excessive discharge. The power bank supports fast charging (Quick Charge 3.0, Samsung AFC, Huawei FCP, Apple 2.4A, Mediatek Pump Express 1.1/2.0, USB DCP). The set includes a USB type C cable.

Excellent device, quickly charges both other equipment and itself. Not too big in size. The possibility to charge devices while charging the power bank means it always stays in one place and is ready in case of emergency.

Great power bank, charges quickly and doesn’t take up much space. It’s a must-have both at home and for longer trips. It’s worth buying a case, even from another manufacturer, so it doesn’t move around in your backpack.

The power bank holds a charge perfectly. During a four-day bike trip, it charged my phone and still had one level of charge left. It charges very quickly, and then charges the phone just as fast—even faster than other models.

For me, this power bank is a real hit. Compared to my previous one (a well-known brand from an electronics store), the Green Cell model is definitely more favorable. High build quality, durability, aesthetics, attractive price, and usefulness... as always, fast shipping from Militaria. Both the product and the store I rate 5/5.

The power bank works flawlessly, has many different ports—it charges well, is sufficient for trips outdoors to power basic electronics. Fast shipping, product well protected from damage. I recommend it.

Very good power bank, product as described. Its shape is unusual, but overall it makes a positive impression. Very fast shipping, product well protected.
