Five high-capacity Power bank batteries with fast charging

The Gelius brand powerbank battery is one of the most affordable 20,000 mAh models, especially if we consider models with fast charging. And here they claim support for the most current protocols, including Quick Charge 3.0 and Power Delivery. Accordingly, the energy replenishment of a smartphone or other mobile device will occur at a power of up to 18 W (per port).

Despite its affordability, the Gelius Pro Edge 3 PD is notable for its durable aluminium alloy body. And at the end, next to the ports, there is a small display showing the current charge level of the power bank as a percentage.

A model with a capacity of 20 thousand mAh is actually capable of transferring 12,600 mAh to other devices. This will be enough to charge most tablets with a screen of 8 - 9 inches to 100% twice or up to 4 times for current smartphones. You can connect up to 3 devices at the same time, because there is a pair of USB A and one USB C.

The last port is equipped with a wire and is also intended to power the power bank itself. For the same purposes, not only the usual (but already slightly outdated) microUSB connector is provided, but also Lightning - very relevant for owners of Apple equipment.

Minor shortcomings of the model include the close location of most ports to each other (with the possible exception of Lightning). Users themselves note that the process of charging the Powerbank battery takes a lot of time. But even despite this, the Gelius Pro Edge 3 PD looks like a pretty interesting model, especially in the low-cost segment.

The 20 thousand mAh version of the Bipow power bank is positioned by the BASEUS brand as standard, along with the 10 thousand mAh lite model and the high-capacity variation - Bipow 20W 30000. In addition, the batteries offered for sale differ in design - they are available in white and black versions.

BASEUS Bipow 20W 20000 weighs about 450 grams and is 3 cm thick. At the same time, the nominal capacity of 12 thousand mAh should be enough for approximately 4 charges of an iPhone 11 or 12, as well as for 2 to 3 cycles of replenishing the capacity of Android smartphones with the heaviest » batteries.

The power bank is equipped with 4 ports. Only a pair of USB A with support for the Quick Charge 3.0 protocol works for the output, and microUSB works for the input. A modern “double-sided” USB C with Power Delivery 3.0 is also available. Its power reaches 20 W, which will allow, for example, to replenish up to 50% of the iPhone battery capacity in 30 minutes.

There is support for other fast charging standards, including Huawei SuperCharge Protocol or Samsung Adaptive Fast Charging, which is important for owners of mobile devices of these popular brands.

You can simultaneously connect up to 3 devices to the BASEUS Bipow 20W 20000, including those that require low current (headphones, smart watches, etc.) But in this scenario, the total power to all ports is reduced to 15 W. A convenient display that shows the current charge of the model, current strength and voltage helps to track the work.

The charging process of the powerbank itself will take a lot of time - from 6 hours. For this purpose, a cable with microUSB is included in the package. Of course, it would be better to include USB C, but even with it the input power does not exceed 18 W.

BASEUS Bipow 20W 20000 is a decent power bank if you are primarily interested in fast charging of smartphones.

The power bank from Xiaomi, which goes on sale at the beginning of 2022, has a laconic design made of aluminium. It looks nice, is not too heavy, and at the same time is superior in strength to its plastic counterparts.

Xiaomi Mi HyperSonic Power Bank 20000 with a capacity of 20 thousand mAh has dimensions of 154x74x28 mm, provides a single control button and a simple charge indicator with four LEDs.

The powerbank battery supports today's popular fast charging protocols, namely Quick Charge 3.0 and Power Delivery 3.0 (as well as their earlier versions). It also acquired three ports: a pair of USB A output (with a power of up to 22.5 W) and USB C. Using the latter, you can charge both the power bank itself (up to 45 W) and various connected gadgets (up to 50 W).

You can power up to 3 devices at the same time. And the replenishment time for the external battery itself is about 4 hours (USB C cable included).

Ultra-fast charging (50 W) is possible with a limited set of gadgets - Xiaomi, Redmi and Poco smartphones. So, let’s say, Xiaomi Mi 11 can be fully charged in about an hour. But thanks to support for Power Delivery technology, 45 W of power is available for any compatible devices (including laptops). For example, it is stated that the Lenovo L480 charges to 100% in approximately 2.5 hours.

In addition, there is the possibility of low-current charging. Therefore, the power bank is suitable for “feeding” energy to wireless headphones and speakers, fitness bracelets, etc.

Xiaomi Mi HyperSonic Power Bank 20000 is a universal battery that can quickly charge smartphones or even become an alternative charger for some laptops on a short trip.

Externally, the 2022 debutant from BASEUS is almost identical to the Adaman Metal Digital Display 20000 22.5W. It is also made in an aluminium case, has a capacity of 20 thousand mAh, and is equipped with a teardrop-shaped information screen.

But BASEUS Adaman Metal Digital Display 20000 65W is an older and more advanced version. It is distinguished by an increased length of approximately 1 cm and, more importantly, high power of up to 65 W. This allows you to use the model for charging laptops. Tests have confirmed compatibility with laptops from the MateBook, Honor and Apple lines, and, for example, the MacBook Pro 13 2020 battery can be fully charged once, which will take approximately 2 hours.

By the way, when even three devices are connected simultaneously, the power drops to 30 W, that is, it will still be higher than that of one port on its younger “relative”. And if two gadgets are charged simultaneously, the peak value can reach 63 W.

The power bank received 4 ports - two USB A outputs (up to 30 W), one microUSB input (18 W) and a “double-sided” USB C (65 W) with a supplied cable. It also supports 6 fast charging protocols, including Quick Charge 3.0 and Power Delivery 3.0, as well as proprietary standards from Huawei and Samsung. As a result, in half an hour it will be possible to charge up to 50% of the iPhone 12 or up to 60% of the Huawei P30.

You won’t have to wait long to replenish the charge of the Powerbank itself. Via USB C, the battery will go from 0 to 100% in just 2 hours, but you will need a compatible network device and cable (a 100 W cable is recommended).

If you need a power bank for a laptop or to simultaneously quickly “feed” energy to several mobile gadgets, then the BASEUS Adaman Metal Digital Display 20000 65W is definitely worth a closer look.

The Zmi brand has flourished under the wing of Xiaomi and now often produces power banks that are even more interesting than the parent company. For example, the hero of this review, Zmi QB823, aims to be the ultimate power bank for all occasions. It has a sufficient supply of energy (nominal capacity 20,000 mAh), supports all popular fast charging formats (Quick Charge, Power Delivery, Samsung Adaptive Fast Charging and Huawei Fast Charge Protocol), and the current strength and set of output voltages allow it to quickly charge any gadgets up to to laptops and Nintendo Switch.

The accessory has three connectors. Two of them are USB A with a power of up to 18 W. The third is USB C, which works for input and output. It supports a maximum power of 65 W, which will be enough to power a laptop that supports USB C charging. For example, a MacBook Pro 13 will be fully charged in 110 minutes, and the battery capacity is just enough for a full charge. By the way, the power when connecting several devices at the same time hardly sags and reaches 60 W for all ports.

An equally important feature of the ZMI QB823 is the USB hub function, activated by double pressing the power button. It allows you to connect the power bank to a laptop via USB C and use its two USB A ports to connect flash drives and other accessories. Useful if the laptop only has 2-3 ports and they are always busy. Well, and finally, let’s praise the traditionally smart design: the rounded body made of blue plastic, pleasant to the touch, is somewhat similar to a high-tech cigarette case or a case for designer glasses. Considering all this, the price of $80 (almost 2 times more expensive than a “regular” power bank from Xiaomi) looks more than justified.
