The Su‑Kam Li‑Pro+ 1250 is a lithium‐battery UPS (Uninterruptible Power Supply) offering a clean, reliable power backup solution with a 5‑year warranty, which is quite substantial for both the UPS electronics and the battery pack. It uses pure sine wave output, which means the power it delivers is in a smooth waveform, making it safe for sensitive electronics (computers, routers, LED TVs, etc.), avoiding issues like noise, interference, or heat buildup that can come from modified or square wave UPS devices.
The front panel features an LCD or display, allowing the user to monitor status (load, battery charge, perhaps warning of overload or low battery), something you see in many high‑end UPSes. The design appears to be “Make in India” stamped, showing it is domestically manufactured. Being lithium, the device likely has a Battery Management System (BMS) embedded to protect against overcharging, over‑discharging, thermal issues, and to optimize battery health. The lithium battery makes the backup unit lighter, smaller, more efficient, and much lower maintenance than lead‑acid battery UPSes. It should also charge faster and retain more usable capacity over its lifetime.
Because of the 5‑year warranty, the manufacturer is signaling confidence in both its power electronics (inverter, controller) and battery durability. The Li‑Pro+ 1250 capacity suggests that it can support moderate loads for a reasonable standby duration (lighting, fans, router, etc.) though runtime under full load will be shorter. Also, because it’s a lithium UPS with pure sine wave, one can expect better performance under varying input voltage, maybe a wide input voltage range so that it tolerates brown outs without immediately switching to battery (this helps extend battery life).
