Gadgets for power outages

2E PB2502 is a power bank with a digital display, a high output power of 100 W and a rather large capacity of 24,000 mAh. Of course, when converting standard 3.7 V lithium polymer batteries to the voltage required for a particular device, some electricity will be lost. But even a MacBook will charge from zero to one hundred percent in just an hour and a half.

The power bank is reliably protected from overdischarge and short circuit. The optimal voltage and current for charging a smartphone, tablet or laptop are automatically selected. The two most popular fast charging standards are supported: Power Delivery via a USB Type-C port and Quick Charge via two Type-A ports. True, in the second case the speed will be only 22.5 W.

You can charge at least three gadgets at the same time, and the kit comes with a pair of USB cables: Type-A and double-sided Type-C. The second is capable of transmitting up to 100 W of power to other devices, but the power bank itself charges at a maximum speed of 65 W. It takes about two hours to fully charge, and the power bank weighs about half a kilogram.

ColorWay CW-CHS041PD is a network charger with four USB ports and a power of 100 W. At this speed, it can charge both one energy-intensive gadget, such as a laptop or power bank, and a total of several less power-hungry ones: smartphones, tablets, wireless headphones, etc. Two newfangled USB Type-C ports, two more classic Type-A.

Thanks to the smart USB Auto ID chip, all fast charging protocols are supported, even relatively rare ones. Namely Power Delivery PPS 3.0 100W, Qualcomm Quick Charge 4.0, Apple Fast Charge, Samsung AFC, Huawei FCP/SCP and Realme/OPPO Super VOOC. The latter is especially in demand, because commercially available chargers and power banks with its support can be literally counted on the fingers of one hand.

The charger is built on advanced GaN transistors, which are more compact, cooler and more energy efficient than their silicon predecessors. Implemented protection against power surges, short circuits, overload and overheating. The case is made of durable and fire-resistant plastic that can withstand temperatures up to 850°C.

nJoy Renton 650 Plus is a linear-interactive uninterruptible power supply and also a voltage stabilizer. Equipped with four sockets for connecting computer and household appliances with a power of up to 650 volt-amperes or 360 watts. It also has two USB ports for charging mobile gadgets: Type-C at 30 W and Type-A at 18 W.

It is capable of equalizing the voltage of the household electrical network both during strong drops down to 162 V and during jumps up to 290 V. As a result, it produces 230 volts similar to a sine wave. The perforated case allows you to do without a fan and, accordingly, any noise. The capacity of the built-in lead-acid battery is approximately 16 watt-hours.

At 100% load, the battery only lasts for one minute of work, which is, however, enough to save unfinished work on the PC, and at 25% - for 18 minutes. There is no liquid crystal display, instead LED indicators are used. Supports cold start, automatic restart after power restoration, and off-line charging.

Marsriva MP6 is a relatively inexpensive charging station with a pure sine wave output, a rated power of 600 W and a battery capacity of 512 Wh. This is enough for 27 smartphone charging cycles, 54 drone charges, 8 hours of TV operation, 4.5 hours of individual heating gas boiler operation or 1.5 hours of multicooker operation.

In addition to two 230 V sockets, there are two more 12 V DC connectors and a car lighter socket. Of the four USB ports, one Type-C supports 60W Power Delivery fast charging for laptops. The station itself can be charged in several ways: from the mains, the cigarette lighter, a solar panel, and also additionally through the Type-C port, which in total will not exceed 180 W.

The station is equipped with a reliable lithium iron phosphate battery LiFePO4, which does not lose its capacity even after 3000 recharge cycles. The station weighs almost 7 kg, but is equipped with a convenient handle for carrying. The informative display displays the operating status of the device, namely: battery status, input and output power.

Canyon CND-SP100W is a solar panel that generates environmentally friendly electricity. In summer, when the sun shines at its maximum angle, it produces up to 100 W of power. But thanks to its monocrystalline structure, it is capable of generating at least some electricity even in cloudy weather. Thanks to its IPX4 waterproof rating, it can be used in the rain.

The XT60 unified connector is designed to connect to a charging station or to another solar panel in cascade to increase generation power. By the way, Canyon’s assortment includes a ready-made set CND-SP200W2P of two similar panels with a total power of 200 W, which is more affordable.

In addition to the XT60 connector, there are three USB ports: two Type-A with Quick Charge 18 W fast charging protocol for smartphones and one Type-C Power Delivery 45 W for laptops. The panel weighs a moderate 4 kilograms and consists of four folding sections, so it can even fit into a travel backpack. Even if with losses, it can still be installed in an apartment on a balcony, including behind glass.
