Bricks: The best power banks with a very large capacity - from 40,000 mAh

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 2023 debutant from the Sigma brand is a power bank with an impressive capacity. Of the total 50 thousand mAh, the built-in lithium-polymer battery is capable of delivering up to 31,000 mAh to devices. This, for example, is enough for 10 power cycles for the iPhone 14 Pro, at least six charges for “long-playing” Android smartphones and up to five for average tablets.

The Sigma mobile X-Power SI50A3QL has a multi-level protection system, so that the accessory is not afraid of overheating, power surges, short circuits and other force majeure.

In total, the power bank has 6 ports: four “classic” USB output ports, a microUSB input and a bidirectional Type C (with included cable). One of the USB A supports fast charging protocols, and their total list is very large and even includes very rare standards, such as OPPO VOOC or OnePlus Dash Charge. As a result, this connector is capable of delivering 22.5 W to connected devices, while the other three are 15 W. The output power of Type C in Power Delivery mode reaches 20 W, which also saves time on powering mobile devices.

It is stated that up to 5 gadgets can be charged at the same time. But even when recharging 2 devices at once, the power decreases, that is, the recharging speed sags. Low current operation is also supported, which will be useful for owners of fitness bracelets, smart watches, wireless headphones, etc.

Considering its capacity, the portable battery is moderately bulky (161x82x53 mm) and has an average weight (1.1 kg). For clarity, a display is proposed that counts the remaining charge as a percentage. But when the battery is completely discharged, it will take a long time to replenish its capacity - up to 18 hours. In any case, Sigma mobile X-Power SI50A3QL is a balanced power bank in terms of capabilities and price.

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.

The power bank battery of the Choetech brand can be classified as a solution in the advanced price category. There is a very capacious battery capable of delivering almost 44 mAh of energy to connected devices (with a total value of 69.6 thousand mAh). This is enough to repeatedly fully charge smartphones, tablets and even laptops or other devices.

Choetech B661 is ready for adverse operating conditions, such as hiking. It received a case with IP65 protection and port plugs that protect them from moisture, dust and other negative influences. There is also a flashlight here: it will allow you to illuminate something, but can also be used to send an SOS signal.

The portable battery is suitable for charging laptops away from power outlets. For these purposes, USB C with the Power Delivery protocol and operating values up to 60 W is provided, as well as a DC connector. The peak output power for the latter is even higher - 70 W, in addition, the package includes 8 adapters for compatibility with different laptops. Another feature of this port is a voltage switch for selecting a safe recharge mode.

By the way, the DC connector allows you to speed up the charging process of the power bank itself, because the current in this case can reach 4 A, and the peak power - 96 W.

In addition to the connectors listed above, the model has another Type C and USB A up to 22.5 W. On the back of the case there is a wireless charging zone (10 W), which can work to recharge compatible smartphones simultaneously with the ports. The power bank is also equipped with another very rare outlet - a 12 V cigarette lighter socket. With its help, for example, you can power a car refrigerator, vacuum cleaner or air pump.

The high cost of the accessory, taking into account the capabilities, is rather a disadvantage, while the heavy weight (1.6 kg) and large dimensions (228x125x44 mm) are still considered disadvantages. But if you need a power bank with power for laptops, a cigarette lighter and wireless charging, then the Choetech B661 has practically no competitors.

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.
