Mini UPS for Router, ONU & Camera - Keep the Internet On During Load-Shedding

Nothing is more frustrating than a work-from-home session or an important call getting cut off the moment electricity goes out. A mini UPS is a small backup battery unit that plugs between your router or ONU and the wall socket - so when the power cuts, your internet keeps running automatically, with zero interruption. Gadgeterians stocks the SKE 432P Mini UPS and the SKE SK616 Mini UPS, both designed specifically for Bangladesh's regular power outage conditions.

• Instant Switchover - Power cuts without any reboot or reconnection delay for your router or ONU
• Multiple DC Output Ports - Supports 5V, 9V, and 12V outputs to fit most router and camera power requirements
• IP Camera / CC Camera Support - Keep your home security cameras recording even during outages
• 4–10 Hour Backup - Enough to ride out most load-shedding cycles in Bangladesh
• Overcharge & Short-Circuit Protection - Built-in safety circuits protect both the UPS and your connected devices
• Compact Form Factor - Small enough to mount on a wall or sit behind your router without taking up space
• No Maintenance Required - Just plug in and forget; charges itself when electricity is on

Mini UPS units at Gadgeterians are priced from ৳2,250 to ৳3,250 - a one-time investment that pays for itself the first time it saves your work during an outage. Browse all mini UPS →

Rechargeable Batteries - Replace Disposables for Good

Still buying single-use AA or AAA batteries every few weeks for your remote controls, wall clocks, torches, and wireless mice? Rechargeable batteries pay for themselves quickly - and they're better for the environment too. Gadgeterians offers the AiVR USB Rechargeable AAA Batteries (4-pack, 900mWh, USB-C charging) and the 21700A Lithium-Ion 5000mAh battery (Made in Japan) for high-drain devices like torches and power tools.

Rechargeable batteries start from ৳500 per cell up to ৳1,300 for a 4-pack of USB-chargeable AAA batteries. Browse all batteries →

Power Bank vs Mini UPS vs Rechargeable Batteries - Which One Do You Need?

Each type of backup power gadget solves a different problem. Here's a quick guide to help you pick the right one - or the right combination.

Backup Power Gadget Buying Guide for Bangladesh - What to Check Before You Buy

Load-shedding patterns, commuting habits, and device usage all vary from person to person. Here's how the Gadgeterians team recommends thinking through your backup power purchase so you get exactly what you need.

1. Identify Your Actual Backup Need First

The biggest mistake buyers make is buying a power bank when what they actually need is a mini UPS - or vice versa. Ask yourself: is the problem that your phone dies during the day, or that your internet goes down during load-shedding? If it's your phone, get a power bank. If it's your router and internet connection, get a mini UPS. If your remote controls and torch batteries drain too fast, rechargeable batteries are the answer. Many households in Bangladesh need all three - but start with whichever problem bothers you most.

2. Choose Power Bank Capacity Based on How Long You're Away

A 10,000mAh power bank gives roughly 2–2.5 full charges for an average smartphone, which is enough for a day in Dhaka. A 20,000mAh model handles a full day plus evening usage without breaking a sweat - and can also charge earbuds or a smartwatch simultaneously. The Hoco J142 at 100,000mAh is overkill for daily commuting but excellent for extended travel, camping in the Chittagong Hill Tracts, or as a household emergency backup when outages stretch into the night. Bigger isn't always better - heavier capacity means heavier weight.

3. Look for Fast Charging on Both Input and Output

In Bangladesh, where power windows during load-shedding can be unpredictable, a power bank that tops up quickly is a serious advantage. Look for at least 15W–22.5W output to fast-charge your phone from the power bank, and 18W+ input so the power bank itself refills faster when electricity returns. Models like the Baseus Adaman (22.5W) and Joyroom JR-PBC07 (30W with dual cables) are particularly good at this. Avoid generic no-name power banks that claim fast charging but don't deliver.

4. For Mini UPS - Match Output Voltage to Your Router's Requirements

This is the most commonly overlooked detail when buying a mini UPS. Your router's power adapter will have a voltage printed on it - usually 9V or 12V, sometimes 5V. Your mini UPS must support that exact voltage output. The SKE models at Gadgeterians support multiple DC output voltages (5V, 9V, and 12V), making them compatible with the vast majority of routers and ONUs sold in Bangladesh. Always double-check before ordering - an incompatible voltage can damage your router or simply not power it on.

5. Consider Wireless and MagSafe Power Banks If You Use an iPhone

If you have an iPhone 12 or newer, a MagSafe-compatible power bank like the Joyroom JR-PBM11 Qi2 or the Momax 1-Power Pass Soda Pop snaps magnetically to the back of your phone and charges without any cable. This is particularly useful on Dhaka commutes where plugging in a cable while standing on a bus is awkward. The kickstand built into some models also lets you prop your phone up while it charges - handy for video calls during the day.

6. Rechargeable Batteries - Match the Size and Chemistry to Your Device

Standard AA and AAA rechargeable batteries work in most household electronics - remote controls, wall clocks, wireless keyboards, and children's toys. The AiVR USB-rechargeable AAA 4-pack is a great starting point. If you use a high-powered torch for load-shedding emergency lighting or outdoor adventures, the 21700A lithium-ion cell (5000mAh) is significantly more capable than standard AA sizes. Always check what size and voltage your device requires before ordering - mixing battery sizes or chemistries is a common and avoidable mistake.

Frequently Asked Questions - Backup Power Gadgets in Bangladesh

Q: What is the price range of power banks at Gadgeterians Bangladesh?

Power bank prices at Gadgeterians range from ৳1,900 for the Baseus 20,000mAh 15W model up to ৳5,999 for the Hoco J142 100,000mAh 22.5W heavy-duty unit. Mid-range options like the Joyroom JR-PBC07 30W (৳2,800) and the Joyroom JR-PBM12 Wireless (৳2,650) offer the best balance of capacity, fast charging, and value for most users in Bangladesh. MagSafe wireless power banks like the Momax Soda Pop are available at ৳3,500.

Q: Will a mini UPS keep my router on during load-shedding in Bangladesh?

Yes - that is exactly what a mini UPS is designed for. When mains power cuts, the mini UPS switches to its internal battery in milliseconds, so your router never reboots and your internet connection stays live. The SKE models at Gadgeterians provide 4–8 hours of backup depending on your router's power draw, which is more than enough to ride out most load-shedding cycles in Dhaka and other divisions. You plug it between the wall socket and your router's power adapter - no configuration required.

Q: Can one mini UPS power both my router and my ONU at the same time?

Most mini UPS units sold in Bangladesh - including the SKE models at Gadgeterians - have multiple DC output ports at different voltages (5V, 9V, 12V), allowing you to connect both a router and an ONU simultaneously, provided their combined power draw stays within the UPS's rated output. Check each device's power adapter for its voltage and wattage before connecting both. Our team can help you verify compatibility before you purchase - just send us a message with your router and ONU model names.

Q: What is the difference between a 10,000mAh and 20,000mAh power bank - which should I buy?

A 10,000mAh power bank gives roughly 2–2.5 full smartphone charges and is slim enough to fit in a jeans pocket - ideal for daily commuters who top up once a day. A 20,000mAh power bank provides 4–5 full charges, can power two devices simultaneously, and is better for full-day outings, travel, or if you also charge earbuds and a smartwatch. If you frequently experience overnight load-shedding and need to keep multiple family members' phones charged, the 20,000mAh models (starting at ৳1,900) are the smarter investment.

Q: Are the rechargeable batteries at Gadgeterians safe for regular electronics like remote controls?

Yes. The AiVR USB Rechargeable AAA batteries are standard 1.5V output, making them compatible with remote controls, wall clocks, wireless keyboards, and most household electronics. They charge via USB-C (cable included), so you don't need a separate charging dock. The 21700A lithium-ion cell is a higher-voltage, higher-capacity format intended for high-drain devices like powerful torches and specialty electronics - it is not a standard AA/AAA replacement. Always match the battery format and voltage to your device's requirements.

Q: How do I check if a power bank is genuine and not a fake inflated capacity one?

Fake or exaggerated capacity power banks are a real problem in the Bangladesh market - some budget products claim 20,000mAh but deliver a fraction of that. At Gadgeterians, we test capacity before listing products for sale. When you receive your power bank, you can verify rough capacity yourself by fully charging it, then running it down charging a known phone (most modern phones have around 4,000–5,000mAh battery) and counting how many full charges you get. A genuine 20,000mAh unit should yield 3–4 phone charges accounting for conversion losses. If results seem off, contact us and we'll resolve it.

Q: Does Gadgeterians deliver backup power products to areas outside Dhaka?

Yes - we deliver all backup power gadgets, including power banks, mini UPS units, and rechargeable batteries, to all major cities and divisions across Bangladesh: Dhaka, Chittagong, Sylhet, Rajshahi, Khulna, Barishal, and Cox's Bazar, as well as most Upazila-level locations through our courier network.
