About
What is a UPS?
UPS stands for Uninterruptible Power Supply (UPS). It is a system that’s designed to keep the power running at all time even when the main power grid goes down (a blackout, or loadshedding), or during power surges or sags (a brownout). Depending on the size of the battery in the UPS, this can sustain power for a few minutes to allow you the time to safely shutdown appliances to prevent damage as a result of a sudden shutdown, or it can sustain power for hours to allow you to continue enjoying the use of appliances (such as watching TV).

Realistically, what can this UPS run, and for how long?
This UPS can power your Wifi, Modem, and Laptop, Phone Chargers and 3 Lamps for 4h32m. Or alternatively one TV (only) for 4h32m.
In more scientific words, it can power 150Watt (Wifi & Modem 40W, Laptop 60W, Phone chargers 8W, 3x LED lamps/lights 30W) for 4h32m whilst keeping 35% of the “juice/energy” in the battery so you don’t discharge the battery too deeply (this prevents damage).

How long will this last?
It will last approximately 500-800 cycles / loadsheddings, or approximately 5 years.
