If you are working from home and rely on a Wi-Fi connection for a smooth workflow, then you should probably have a power backup, so that your work is not affected. If you are in a Zoom meeting or watching an important live stream event, a power outage could mess up things.
We evaluated the performance of each model in several key areas:
1. Peak power output in watts:
This test revealed the maximum load that each mini UPS could handle. We connected the mini UPS to power and then turned it on. After unplugging the mini UPS, we left it on its battery and plugged in household appliances with known power draws. This included a range of 50W halogen bulbs, several 10W lamps and a 100W fan. The mini UPS then shut down when the battery was full. We then added up the maximum power draw based on the appliances plugged into it and recorded the maximum output as watts.
2. Batteries (watt-hours or Wh) and runtime:
Manufacturers frequently publish runtime ratings which indicate how long a mini UPS can keep devices running at different wattages. We tested the top candidates under two loads, 20 W and 300 W. These are the power draws of a router and a household modem. After overnight charging each mini UPS, we connected a Kill-A-Watt meter to one of the battery-backed outlets. After setting each mini UPS overnight, we connected six 300-watt halogen bulbs to the mini UPS and then unplugged it. The mini UPS was left running on its battery. We recorded the run time (run time) and the kilowatt hours (kWh), which were used to calculate the battery’sbattery’s effectiveness in watt-hours. The test was then repeated with two 10W lamps. We measured the run time using a 20W load.
3. Surge protection:
We used the same equipment and protocol to test surge protectors. We zapped each mini UPS using 5,000-volt power surges. Then we measured how many volts they allowed through. As you want to enable as little voltage as possible through your devices, a lower let-through voltage (also known as clamping voltage) is preferable. We didn’tdidn’t want to set any hard limits because surge protection isn’tisn’t the main purpose of mini UPSs, but we preferred models with lower let-through voltages.
Maximum output (watts from USB-A ports): If applicable, we connected a PortaPow USB monitor and a Drok USB loads tester to each port. Then, we turned up the power until the docks were overloaded. To calculate the total output, we multiplied the amps and voltages.
4.Look and Feel:
We looked at the usability and layout of outlets and ports, as well as the size and shape of the unit and overall design.
How to Maintenance Mini-DC UPS?
It is important to understand what a mini UPS can and cannot do. A mini UPS can damage the internal components of high-drain devices, such as large office equipment like laser printers or paper shredders. It can also cause battery degradation and invalidate its warranty. It would help if you did not have to worry about small electronics or office equipment that doesn’tdoesn’t have moving parts. However, read the manual if you need more than a desktop computer.
Never plug a mini UPS into the surge protector or vice versa. You risk overloading the mini UPS, tripping a fuse or breaking it, and causing surge protection to be cancelled instead of doubled.
You should also avoid plugging a mini UPS into an extension cable. The excess load could cause the mini UPS to melt and overheat. You can move your mini UPS closer to an outlet or spend $100 to have an electrician install one. Neither of these options is better than replacing damaged electronics or accidentally starting a fire.
Your mini UPS is sealed, and the lead-acid battery will remain charged for as long as it is plugged in. This should ensure that it can continue to work well for many years. However, batteries can degrade over time, so it is best to unplug your mini UPS from the wall outlet once a year with your devices running. This will ensure that the mini UPS continues to power them for the expected time.
A mini UPS unit is not designed to last forever like other electronics. You should be able to replace the battery several times before replacing the whole unit. APC and CyberPower sell replacement batteries that work with our top, upgraded picks. Some third-party battery manufacturers also offer compatible batteries. Amazon Basics does not sell spare mini UPS batteries. However, for our budget pick, you can find a compatible replacement from Duracell, Mighty Max and other well-known brands. If in doubt, ensure that the label’slabel’s voltage and terminals (F1 or F2) match the unit.
Most mini UPS units use sealed lead-acid battery packs, which can be recycled with almost every type of battery. While most Americans recycle metal, plastic, paper and cardboard regularly, only half of those who use batteries or other electronic waste can recycle them. This problem is because landfill batteries can leach harmful chemicals and heavy metals into the soil and water. This means that to manufacture new electronics, manufacturers must obtain more raw materials than they can salvage from the old ones. There are a few options to recycle old mini UPS batteries and mini UPS units (once they wear out).
Use the Earth911 database to determine if municipal recycling facilities take electronic waste.
Drop off mini UPS batteries and other used batteries at a Call2Recycle collection location.
You can mail your mini UPS unit, including the battery, in a TerraCycle Power Strips & Cords Zero Waste Box. Also, include any surge protectors, power strips, and extension cords you don’t want to keep.
Mail in an EasyPak Electronics Recycling Box from TerraCycle Regulated Waste to recycle various batteries and other electronic waste.
If you want to offer a better solution, which can intervene effectively whenever there is a power failure or a voltage surge, you may decide to purchase an uninterruptible power supply. Together with the large format mini UPS, often used to secure a computer or other equipment that requires a lot of energy to operate, there are those that can be defined mini UPS. Specifically, it’s about batteries capable of powering the devices you will connect whenever there is a power failure, while in normal conditions they will only take energy from the home network and transfer it to the device you want to power. They therefore work like classic uninterruptible power supplies with the difference that they are much smaller and are able to power only small electronic devices, such as a modem router, an access point or even a security camera.
