The WGP Optima 302 is a 27W mini DC UPS built to keep your router, ONU, and IP camera running through a power cut — no rewiring, no bulky battery box, just a plug-and-forget backup that sits quietly behind your modem.
If you've ever lost internet the moment load-shedding hits, you already know the real cost isn't the dark room — it's the dead router. Video calls drop, CCTV footage stops recording exactly when you need it most, and smart home devices go silent. The WGP Optima 302 27W UPS for Router exists to solve that one specific, everyday frustration, and CSI — Bangladesh's leading IT products distributor — brings it to you as a genuine, warranty-backed unit rather than an unbranded knockoff from a random stall.
Why This Mini UPS Earns a Spot Behind Your Router
It buys you real backup time for the devices that matter most during an outage, without needing an electrician or a separate battery bank.
Most people don't need three hours of backup for a whole household — they need 60 to 90 minutes of uninterrupted internet, surveillance, and network access while the grid comes back or the generator kicks in. That's precisely the gap the Optima 302 fills. Its 13500mAh (4500mAh × 3) 21700 li-ion battery pack sits between your existing power adapter and your networking gear, switching over instantly when mains power fails — so your ONU never reboots, your Wi-Fi never drops mid-call, and your camera keeps recording.
From a hands-on standpoint, this is the kind of accessory people forget exists until the day it saves a client call, a remote work deadline, or a break-in caught on camera because the DVR/camera stayed powered. That's the real value proposition — not a spec sheet, but continuity when it counts.
Built for Multi-Device Backup, Not Just One Gadget
The Optima 302 runs up to three low-voltage devices at once through four dedicated output ports, so a single unit can protect your router, ONU/modem, and camera together.
- Two DC 12V / 2A outputs — power a router and an ONU/modem simultaneously
- One DC 9V / 1A output — suited to smaller routers or accessories
- One USB Quick Charge port (5V/3A or 9V/2A) — charge a phone, power a smart speaker, or run a USB-powered camera
This four-port layout is the practical differentiator: instead of buying three separate mini UPS units for three devices, one Optima 302 can realistically back up your entire home network corner — router, ONU, and a security camera — off a single compact unit measuring just 116 × 75 × 28 mm and weighing under 300 grams.
Who Actually Benefits From This UPS
Home broadband users, small offices, and CCTV/camera setups in load-shedding-prone areas benefit the most from the Optima 302.
- Remote workers & freelancers who can't afford a dropped video call or lost VPN session mid-task
- Small shops & offices running a router plus a security camera that must record without gaps
- Families relying on home CCTV where continuous recording during outages matters for safety
- Gamers & streamers who need the router to stay alive during short grid interruptions
- Landlords or property managers maintaining always-on network access across a building's ONU/router setup
Safety Engineering That Protects Your Other Devices Too
The Optima 302 includes over-charge, over-discharge, overload, short-circuit, and temperature protection — meaning it safeguards your router and camera investment, not just itself.
A cheap, unprotected battery pack can actually damage the router or ONU it's meant to protect if voltage isn't regulated properly. The Optima 302's built-in intelligent power management is what separates a proper mini DC UPS from a generic power bank rigged with DC cables — it's purpose-engineered for continuous, always-plugged-in duty behind networking equipment, not occasional mobile charging.
The CSI Buying Advantage
Buying the WGP Optima 302 from CSI means genuine WGP stock, 1-year official warranty, and after-sales support from a distributor with a physical service network across Bangladesh — not a marketplace gamble.
As Bangladesh's top IT products distributor, CSI sources WGP's mini UPS lineup directly, which means what you receive matches the exact specification listed — the same 21700 li-ion cells, the same 27W-rated output, the same certified protections. Every unit ships with:
- Official 1-year replacement warranty, honored at CSI's own service centers
- Secure, tracked delivery across Dhaka and nationwide
- Pre-sale technical guidance via CSI's online support desk if you're unsure which mini UPS fits your router/ONU combo
- Access to CSI's wider WGP brand lineup for bundling with other networking backup accessories
Optima 302 vs. the Rest of the Mini UPS Shelf
Compared to basic single-port power banks repurposed as router UPS units, the Optima 302 stands out for genuine multi-port output and a higher-capacity 21700 cell design.
Many budget alternatives only offer one or two DC outputs and rely on older, lower-density battery cells. The Optima 302's 13500mAh 21700 li-ion configuration gives it a meaningfully longer backup runtime per charge cycle while still fitting in one hand. If your household or office needs a larger buffer — say, for a bigger router plus an extended camera setup — CSI also carries the WGP Optima 302 27W 10500mAh Mini DC UPS, the lighter-capacity sibling in the same series, if a smaller footprint suits your setup better.
Setup Takes Minutes, Not Tools
Installation is plug-and-play: connect your router/ONU's existing DC cable to the matching output port, plug the Optima 302 into mains power, and it starts charging and standing by immediately.
- Match your router or ONU's original DC voltage (12V or 9V) to the correct output port
- Connect the device to the Optima 302 using its existing power cable or a compatible DC connector
- Plug the Optima 302 into a wall socket to begin charging
- Once charged, it automatically switches to battery power the instant mains power cuts
No configuration, no app, no manual switch-over — the whole point is that it works invisibly in the background.
Frequently Asked Questions
Can the WGP Optima 302 power a router, ONU, and camera at the same time?
Yes. It has four output ports — two DC 12V/2A, one DC 9V/1A, and one USB QC port — so it can run a router, an ONU, and a small camera or USB device together, up to its 27W maximum output.
How long does the WGP Optima 302 keep a router running during a power cut?
Backup time depends on the connected device's power draw, but its 13500mAh 21700 li-ion battery is sized to comfortably cover typical short-to-medium load-shedding windows for a router and ONU running together.
Is the WGP Optima 302 safe to leave plugged in permanently?
Yes. It's designed for always-on, always-plugged-in use behind networking equipment, with built-in over-charge, over-discharge, overload, short-circuit, and temperature protection.
What is the difference between the WGP Optima 302 27W 13500mAh and 10500mAh versions?
Both share the same 27W output and four-port design; the 13500mAh version uses a higher-capacity 21700 li-ion pack for longer backup runtime, while the 10500mAh Optima 302 offers a slightly lighter-capacity alternative.
Does the WGP Optima 302 work with any router or only specific brands?
It works with any router, ONU, or camera that runs on DC 12V or DC 9V input within its port ratings, which covers the vast majority of home and small-office networking equipment sold in Bangladesh.
Where can I buy a genuine WGP Optima 302 in Bangladesh with warranty?
CSI, Bangladesh's leading IT products distributor, sells genuine WGP Optima 302 units with 1-year official warranty and nationwide delivery through its Mini UPS category.
Why Buy This From CSI
CSI backs the WGP Optima 302 with authenticity, warranty, and real support — the three things a router-backup device needs most since it's meant to be trusted, not just purchased.
A mini UPS is a low-cost, high-trust purchase: it's cheap enough that people rarely research it deeply, but it fails at the worst possible moment if it's counterfeit or poorly made. That's exactly why sourcing it from an established, accountable distributor matters more than it seems. CSI's role as Bangladesh's top IT products distributor means every WGP unit sold carries traceable stock, a genuine warranty claim path, and a support team that answers — whether that's a quick WhatsApp question before you buy or a warranty claim six months in.
