Key Specifications

Physical Properties

• Approximate dimensions: 280 × 100 × 140 mm (Length × Width × Height)

• Weight: ~ 4.3 kg

Performance & Runtime Estimates

• Backup Time: Depends heavily on load. At lighter loads (for example a PC + router or small home setup drawing ≤100-150W), you might get ~ 10-20 minutes of backup. Under heavier loads closer to the 360 W capacity, expect much shorter time.

• Recharge Time: About 6-8 hours to 90% battery charge after full discharge in many listings.

Protection & Other Features

• Surge protection, overload protection.

• Brownout protection (low voltage), over-voltage protection via AVR.

• Intelligent battery management (float charging, avoids overcharge, etc.).

Pros & Limitations

Pros:

• Good for home/office use for devices like PCs, modems, small networking gear, etc.

• The AVR helps to handle the fluctuating mains voltages common in many areas (brownouts & spikes), preserving lifespan of connected equipment.

• Cold-start means even without main AC, you can power devices from battery temporarily.

• Universal sockets: good compatibility with different plugs.

Limitations:

• Simulated sine wave (not a pure sine wave) is likely (many line-interactive UPS of this class use simulated / stepped sine) — might be less ideal for highly sensitive equipment (audio, some PSU-sensitive hardware). [Note: not explicitly stated, but common in this class]

• 360 W is maximum; if you have a high-powered gaming computer + peripherals, you could exceed it; UPS may overload or very short runtime.

• Battery runtime drops significantly with heavier loads.

• SLA battery needs maintenance/lasts limited cycles; after a few years battery performance degrades.

• Only 2 outlets; if you have many devices, you’ll need additional surge strips (but plan their load).
