That staying mentioned, there May be better models around but they may likely be quite a bit costlier AND they may be one and one particular type products.
We have when compared these UPS units across numerous factors, like their measurement, power supply, runtime, and battery recharging time. We checked out what types of environments they'd be finest suited for and their enter voltage and shops, between other factors.
