PC Power PCMU1018LL 20000mAh Mini UPS – Uninterrupted Backup Power for Your Router, ONU & CCTV, Verified Genuine by CSI
The PC Power PCMU1018LL is a 20000mAh mini DC UPS built to keep routers, ONUs, IP cameras, and PoE-based network gear online during a power cut, using zero-delay battery switchover and multi-voltage DC output (5V, 9V, 12V, plus PoE 15V/24V) up to 18W.
Load shedding doesn't ask for permission — it usually hits right when a video call, an online exam, or a client deadline is on the line. CSI, recognized as one of Bangladesh's leading IT product distributors, brings you the PC Power PCMU1018LL so your internet connection doesn't go dark with the rest of the house. This isn't a generic power bank repurposed for networking gear — it's a purpose-built mini UPS engineered specifically around the voltage patterns routers, ONUs, and surveillance cameras actually need.
Why This Mini UPS Earns Its Place Beside Your Router
It matters because standard IPS/UPS units are oversized, noisy, and expensive for the job of keeping just a router and camera alive — the PCMU1018LL solves that with a compact, purpose-built unit at a fraction of the footprint.
Anyone who has waited out a blackout with a dead router understands the frustration — no WiFi means no work-from-home, no CCTV recording, no VoIP calls. A full-size IPS is overkill for a device that only draws a few watts. The PCMU1018LL was designed around that exact gap: a battery unit sized and voltage-tuned for networking hardware, not entire households.
Where It Actually Shines: Real Use-Cases
- Home broadband continuity: Keeps your ONU and router alive so family members don't lose connectivity mid-stream or mid-call during outages.
- Small office & remote work setups: Maintains VoIP, cloud access, and internal network switches when grid power drops unexpectedly.
- CCTV & security monitoring: Prevents surveillance blackout windows — a common vulnerability point that intruders and building managers alike know about.
- PoE network devices: Its 15V/24V PoE-compatible outputs extend backup coverage to PoE switches and access points, not just basic routers.
How the Battery & Output System Actually Works
The unit runs on a 20000mAh lithium cell delivering a maximum 18W across multiple simultaneous outputs (USB, 3x DC ports, and PoE-ready LAN pass-through), automatically switching to battery the instant grid power drops — no reboot, no downtime.
What separates a mini UPS from a basic power bank is the switchover behavior. A power bank requires you to unplug and replug a device manually. The PCMU1018LL senses the interruption and shifts to battery power instantly, so your router never reboots and your active connection session isn't dropped. For anyone attending back-to-back video meetings, that seconds-level difference is the entire point of owning one.
Built-In Protection That Actually Matters Long-Term
The PCMU1018LL includes overcharge, over-discharge, overcurrent, overload, over-temperature, and short-circuit protection — the same safety layer expected in higher-end UPS units, scaled down for compact use.
A lot of budget backup units skip half of these safeguards to cut cost, which shortens battery lifespan and risks connected hardware. Here, the protection circuitry is comprehensive enough that leaving the unit plugged in and charging continuously — which is how most people actually use it — doesn't degrade the battery prematurely.
Honest Limitations You Should Know Before Buying
This is a low-power DC UPS rated for a maximum 18W output — it is built for routers, ONUs, and CCTV cameras, not for desktop PCs, large monitors, or high-draw AC appliances.
We'd rather tell you this upfront than have it returned later. If your requirement is backup for a desktop computer or an AC-powered device, you need a full IPS/UPS system, not a mini DC unit. This product's entire value proposition is precision — it's built narrow and deep for networking-class electronics, not broad and shallow for general power backup.

Frequently Asked Questions
Can the PC Power PCMU1018LL power a desktop computer?
No. Its maximum output is 18W, which is far below what a desktop PC requires. It is designed exclusively for low-power DC electronics like routers, ONUs, and CCTV cameras.
How long can it back up a router during a power cut?
Backup runtime depends on your router's actual power draw, but the 20000mAh capacity is designed to provide extended hours of continuous operation for typical low-power routers and ONUs well beyond a short outage.
Does it support PoE devices?
Yes. The PCMU1018LL includes PoE-compatible output options (15V and 24V) alongside standard 5V, 9V, and 12V DC ports, making it suitable for PoE switches and access points in addition to standard routers.
Is there a delay when switching from mains power to battery?
No. The unit is designed for zero-delay switchover, meaning your router or camera stays powered continuously without rebooting when the electricity cuts off.
Is the PC Power PCMU1018LL sold at CSI genuine?
Yes. CSI sources directly through authorized channels, so every unit sold comes with full manufacturer specifications intact and is backed by official warranty support.
