Product Overview

AI-generated summary

For £42 ex-VAT, the APC CP12036LI is a sensible “save the session” mini UPS for low-power gear that you really don’t want rebooting every time the power hiccups—think Wi‑Fi routers, small VOIP boxes, and a couple of IP camera PoE injectors/switches that aren’t drawing much. It’s the kind of thing I’d recommend to customers who’ve had annoying brief dropouts (especially in offices that rely on Wi‑Fi) and want a bit of breathing room so the network stays up long enough to avoid full reconnections. APC’s value here is reliability and simple behaviour: plug it in, connect your 12V device, and you’re mostly done.

That said, don’t buy it if you’re expecting “minutes of runtime” or protection for anything power-hungry. It’s a compact Li‑ion unit meant for emergency continuity, not backup power. If your aim is to keep cameras or an entire network switch running through longer outages, you’ll hit the limits quickly and it’ll feel like money spent for short-lived benefit. In short: great for small 12V appliances and minor power interruptions; a poor fit if you need sustained backup or you’re powering bigger loads.
