TOP 5 power banks with very large capacity - from 40,000 mAh

The BLOW PB40A external battery is a budget solution, but has characteristics that are comparable to more expensive analogues. One of the key features of this battery is the combination of high capacity and compact size. Despite the claimed capacity of 40,000 mAh, the actual capacity is around 25,000 mAh. This capacity-to-size ratio makes it an excellent companion for long trips and outdoor recreation when access to a power outlet is limited.

Despite its large capacity, the BLOW PB40A battery has compact dimensions of 140x68x27 mm and weighs only 430 grams. Such parameters make it convenient to use and allow you to easily place it in a backpack or bag.

This battery is compatible with most modern gadgets, with the exception of laptops due to their high power consumption. However, it is possible to charge low current devices such as headphones, smart watches, fitness trackers, headsets, etc. The battery supports simultaneous charging of up to three devices via two USB-A ports with Quick Charge 3.0 support and one USB Type-C port with Power Delivery support. It's important to note that the maximum power output is 18W, so waiting for instant charging is not practical. There are also connectors for charging the battery: microUSB, universal USB Type-C (both input and output are used) and Lightning. The battery comes with a USB Type-A to microUSB cable.

An additional convenience of the battery is the large display on the case, which displays the charge level in percentage, which makes it easy to monitor the battery charge status.

Powerbank Hoco J86 Powermaster offers good value for money, providing a large battery with ample ports, fast charging support and additional options. The manufacturer lists the battery capacity as 40,000 mAh (or 148 Wh), but the actual capacity is about 23,600 mAh. This allows the power bank to recharge phones, tablets and other gadgets several times. For this purpose, there are two USB-A ports with a power of 22.5 W each and one USB-C port with a power of 20 W, supporting fast charging. The battery also supports fast charging standards such as Quick Charge 3.0, Power Delivery 3.0, Samsung Adaptive Fast Charging and Huawei Fast Charge Protocol.

The battery itself can be charged via a universal USB Type-C port or microUSB port (for charging only). Charging of the Hoco J86 Powermaster is also fast, but with a power of 18 W. However, thanks to the large capacity of the battery, it will not take long to charge it. The manufacturer also provided multi-level protection against overheating and short circuit.

The design of the power bank is not a key feature and the Hoco J86 Powermaster follows this principle. It has a minimalist design with black and white colors, and with a capacity of 40,000 mAh, it is not surprising that the battery has some weight (almost 800g) and size. However, more importantly, the emphasis is on quality materials and additional features for ease of use. The case is made of fire-resistant materials, there is a strap for easy carrying (although a little short). A small display on the top shows the battery charge level, and the LED panel on the front side allows you to use the battery as a light in case of a power outage or to illuminate evening walks and outdoor recreation.

In addition, the company's range includes other models with higher capacities, such as Hoco J86A Powermaster (50,000 mAh) and Hoco J86B Electric (60,000 mAh).

The Tracer Magni 50000 external battery is a capacious, reasonably priced device that can be useful as a backup power source in a variety of situations. The manufacturer indicates a capacity of 50,000 mAh (or 185 Wh), but the actual capacity is about 31,000 mAh. This is still a fairly large capacity, allowing you to charge smartphones and other devices multiple times. The battery can be used to connect various devices such as tablets, smart watches, wireless headphones and others. In total, the battery has 3 output ports with a maximum power of 20 W: two USB-A with support for Quick Charge 3.0 and one USB Type-C with Power Delivery 3.0. It also supports fast charging technologies from Huawei and OPPO.

One of the advantages of the model is the pass-through charging function, which allows you to simultaneously charge the battery from the outlet and the device from the battery, saving time. To charge the battery, the model itself provides three connectors to choose from: double-sided USB Type-C, microUSB and Apple Lightning. However, charging the battery can take quite a long time - about 12 hours for a full charge.

Understanding that a 50,000 mAh battery cannot be compact, the Tracer Magni 50,000 has dimensions of 160x80x50 mm and a weight of almost 1 kg. There is a carrying strap on the case, but due to its size it will be more convenient to place it in a bag or backpack. The design is simple, the body is made of ordinary plastic. All connectors are located on the top of the battery, and it is complemented by a display showing the remaining charge.

The Romoss brand offers a powerful Powerbank for users who need a large supply of energy for their devices. The battery capacity is 60,000 mAh, although the actual capacity is about 36,000 mAh. This allows you to charge smartphones and other devices multiple times. Despite the impressive capacity, this battery is more suitable for use at home, in the country or on hikes, as it is quite large and weighs more than 1300 g.

Powerbank Romoss PEA60 has 6 different ports: 3 USB-A output, microUSB and Apple Lightning for charging the battery, and a universal USB Type-C that can charge both the battery and devices. USB Type-C has a maximum power of 22.5 W, while USB-A has a maximum power of 18 W for one port and 12 W for the other two. The battery supports various fast charging technologies, including Quick Charge 3.0, Power Delivery 3.0, as well as proprietary standards for gadgets from Samsung, Huawei and other manufacturers.

It's important to note that fast charging only works when one device is connected. The powerbank can charge up to 4 devices simultaneously, but the maximum power of 22.5W will only be achieved with one device connected.

To charge the battery itself, there are 3 ports with a power of 18 W each, and a full charge will take about 14 hours using the appropriate adapter.

The battery case has a display that shows information about current, voltage, remaining power and state of charge. One control button controls the device, and the battery is also equipped with a protection system against various situations such as overcharging, overcurrent, overvoltage and other force majeure situations.

Here we have a powerful Powerbank from the major league, combining high performance, large capacity and fast charging. However, the main advantage of this portable battery is its versatility. Equipped with 6 ports, it is capable of charging almost any type of device: from smartphones and tablets to wireless headphones, smartwatches, drones, cameras and even laptops. With Power Delivery technology and 100W of power, this battery can power laptops and other devices even in environments without electricity.

With an extensive selection of ports, the Powerbank is capable of charging up to 5 devices simultaneously. The most popular of them is USB Type-C, designed both for charging the battery and for connecting third-party devices. It can provide 60W of power to the battery and even up to 100W to external devices. The Apple Lightning port can be used to charge the battery itself, but it only charges 18W.

Among the output ports, a variety of options are available: in addition to the universal one, there is another USB Type-C with a power of 30 W and 3 USB-A ports with a power of 18 W each. With a total battery capacity of 50,000 mAh (actually around 31,000 mAh), this should be enough to charge different devices multiple times. For example, a smartphone can be charged 6-8 times, and in the case of a smaller battery capacity - even 10 times.

Due to its large capacity, the battery measures 15x5x7 cm and weighs just over 1 kg. It is not very comfortable to carry in your hand, but the manufacturer has added several additional features to improve the comfort of use. For example, the battery is equipped with a carrying strap and a display showing the charge level. There is also a lamp - a rectangular panel with LEDs that can illuminate a room or road during power outages.
