BR1000MS: Output capacity of 1000VA/600W.
BR1350MS: Output capacity 1350VA/810W.
BR1500MS2: Output capacity of 1500VA/900W.
All models use sealed lead-acid batteries, which is a maintenance free battery technology. This means that users do not need to add electrolyte, but it is important to note that the battery has a certain design lifespan (usually 2-3 years) and needs to be replaced regularly to maintain performance.
The battery is in a float charging state in mains mode. Once an abnormal mains voltage is detected (dropping below 98V or rising above 139V) or a complete power outage is detected, the inverter will immediately take over. The output voltage in battery mode is stabilized at 115Vac (± 8%) with a frequency of 60Hz, providing a standard operating environment for the vast majority of American electronic devices.
3. Multi purpose USB charging interface: meeting the needs of the mobile era
With smartphones and tablets becoming an indispensable part of life, power sockets are no longer just serving PCs. Back UPS Pro innovatively integrates two USB charging ports: Type-C and Type-A.
Type-C interface: This is currently the charging standard for mainstream Android phones, iPads, and the latest laptops.
Type-A interface: still widely used in most charging devices.
These two interfaces are designed to use the battery power of UPS to charge your mobile devices simultaneously during power outages. This means that in an emergency (such as a massive power failure caused by a storm), your mobile phone and tablet can still be turned on to ensure that you can receive emergency notifications, check weather forecasts, or maintain Internet connectivity through mobile hotspot.
4. Comprehensive surge protection capability
Back UPS Pro offers a surge energy rating of up to 1080 joules. This is a hard indicator to measure the ability of UPS to absorb surges. The higher the Joule value, the stronger the surge impact that the equipment can withstand, and the more comprehensive the protection for the equipment.
Data cable protection:
As mentioned earlier, protecting only the power cord is not enough. Back UPS Pro integrates a 1Gb network cable protection interface (RJ-45, 1 in 1 out) and a coaxial cable protection interface. This function is very important:
It can prevent surges from entering through the "backdoor" (i.e. network or TV cable).
It protects expensive network modems, routers, and network card chips inside the PC.
It provides a firewall for data links without sacrificing network transmission speed (supporting gigabit networks).
5. Intelligent management and LCD display screen
In order to get rid of the "black box" state of traditional UPS, the Back UPS Pro is equipped with an LCD display screen. This screen provides rich information, including:
Input voltage status: Allow users to understand whether the quality of the mains power is stable.
Output load percentage: helps users evaluate whether the current power consumption is overloaded.
Remaining battery capacity and estimated operating time: enabling users to make informed decisions during power outages (such as whether to continue working or immediately save shutdown).
Alarm message: Visual and auditory alerts, indicating overload, battery replacement, or system malfunction.
In addition, after connecting to the PC through the USB interface, users can use the included PowerChute Personal Edition software. This is an easy-to-use automatic shutdown software. It has power and energy management functions. When the UPS enters battery mode and the battery level is low, the software will automatically and safely shut down the computer to prevent improper shutdown and data loss caused by battery depletion. This is particularly important for unmanned remote work environments.

Detailed product specification comparison and operational scenarios
In order to better understand the performance of Back UPS Pro in practical applications, we need to delve into its specific specifications and runtime under different loads.
Input and output characteristics:
Back UPS Pro is designed specifically for the North American market, with standard 120Vac, 60Hz (± 3Hz) input. It can adapt to an input voltage range of 98-139Vac, which means that even in remote areas with unstable voltage, as long as the voltage does not drop below 90V, the UPS can maintain stable output, avoiding repeated battery switching due to voltage dips and extending battery life.
In terms of output, it provides 10 standard NEMA 5-15R sockets. These sockets are divided into two groups:
Battery backup+surge protection sockets (6): These sockets are connected to the inverter and powered by batteries. Important devices (host, monitor, router) should be plugged in here.
Only surge protection sockets (4): These sockets are directly connected to the mains power without passing through the battery. Non critical equipment such as printers and scanners should be plugged in here. The benefit of doing so is to avoid high-power non essential devices such as printers consuming valuable battery capacity, thereby extending the battery life of critical equipment.
