A solid power bank that charges fairly quickly and powers a phone efficiently, and when it isn’t being used, it loses its charge very slowly. It’s clear that it’s better made than other models in a similar price range, and the option to charge up to three devices at the same time proves very practical.
Green Cell PowerPlay 30 30000 mAh Power Bank - Black
The power bank in black is equipped with a lithium-polymer battery (Li-Po) with a capacity of 30000 mAh, allowing multiple recharges of mobile devices without the need for frequent recharging of the power bank itself. The maximum output power of 22.5 W allows for fast charging of compatible smartphones, tablets, sports cameras, and other electronic gadgets.
A solid casing made of durable polymer ensures effective protection against mechanical damage, such as dents and scratches, thereby increasing resistance to wear during daily use outdoors, while travelling, or at work.
Pass-Through function, GC Ultra Charge, Low Power Mode
The device has one USB-A socket and three USB-C sockets. It supports fast charging and allows simultaneous connection of three devices.
The USB-C PD port with a maximum power of 22.5 W, supported by GC Ultra Charge technology, provides accelerated charging of smartphones, sports cameras, and other compatible devices compared to standard power methods.
Thanks to the Pass-Through function, it is possible to charge the powerbank and all connected devices simultaneously, allowing its use as a multi-port charger.
The Low Power Mode allows for safe charging of low-power devices such as headphones, smartbands, smartwatches, and other small accessories.
Four LED indicators inform you of the power bank's charge level, lighting up when the button on the casing is pressed.
Protection against short circuits, overheating, and deep discharge
A high-quality electronic system, with which the device is equipped, monitors the current temperature of the Li-Po cells, protecting against short circuits, overheating, and deep discharge.

Received very quickly. Works great, the battery lasts a long time. Great design. It supports fast charging, which is very convenient. Plus, you can charge several devices.
-
This is already the second Green Cell PowerPlay 20S 20000 mAh power bank I’ve bought. It’s very convenient to use and charges the phone quite quickly. It’s worth remembering, in accordance with the instructions, to fully discharge it from time to time and then charge it back up completely.
-
The power bank is perfect for trips or short excursions; it's great for quickly charging your phone or a drone battery. It's most useful during overnight stays outdoors, where the phone is often needed for various activities.
-
A good option for this price. Large capacity, high-quality materials and assembly, fast charging. Ideal for smartphones, tablets, and gadget charging. Quick delivery is also a bonus!

I bought this Powerbank because I liked its compact size and weight. It's very convenient to carry it every day in your pocket or bag. I used it every day for a week. And yes, it really does have a fast charging function. I also found by experiment that it actually has almost 10,000 mAh. The only thing that's not quite right, and what I'm not satisfied with, is the charging cable included in the package. When using this cable, both the Powerbank and the phone (Redmi Note 14 Pro) heat up quite a lot. And with this cable, there is no fast charging at all. But after replacing it with the charging cable from my phone, everything started to work as it should. The bank's own charge is enough for me to charge my phone twice to 60%. Overall, I'm happy with the price and quality of the product. But I advise you to replace the standard cable with something more adequate.
-
After one and a half years of use, I can confidently recommend it. It works well during trips lasting several days, operates flawlessly, and charges exactly as specified. The low voltage solution is great, for example for charging a watch. I highly recommend it.
-
Powerful battery, easy to use, heavy but compact, ideal for long trips of a few days. Fast charging available and suitable for every electronic device (laptop, tablet, mini speaker, etc.), top notch.
-
Great power bank, the battery lasts a long time and I have no trouble charging my phone, camera, or even a small laptop with it. The only thing that bothers me is its shape – sometimes it slips out of my hand because of that, but apart from that the device is very good.
-
So far, the product fully meets my expectations. It matches the manufacturer's description. After a few months of use, I intend to write another review. I definitely recommend both the product and the shop.
-
Very useful battery, but it's a shame you can't recharge it using the USB A port—only the two USB-C ports allow charging. The diamond-shaped design is a bit confusing.
-
Compact and full of features. The radio is quite basic but works properly, the lamp is quite bright and the SOS signal is very loud. There is even a battery level indicator.
-
So far, the power bank meets my expectations and charges my phone well. Importantly, I can see that it has a substantial energy reserve – exactly what I needed. I was looking for a power bank that wouldn’t let me down, and so far I can recommend this model. We’ll see how it performs after a year or two, as I’ve only had it for a short time. It charges the Samsung S24 Ultra efficiently and after several charges of both this and another phone, only one LED has gone out. I’ve also used it as a UPS and this feature is useful. Charging the power bank at the same time as another device causes no problems.
-
After a long break, I bought a power bank again and I am very satisfied. I take it to work and on trips because it is handy. It charges quickly and just as efficiently charges my Samsung. The only downside is the short cable included, so I use a longer cable which I bought separately.
-
I have used this equipment both when travelling and on a daily basis, and over time I have come to appreciate it for its reliability. The battery lasts a long time, so I don't have to check its charge level often.
