GearUP 12V/3A Power Adapter for WGP and Router (AC 100-240V To DC 12V, 3A)

GearUP 12V 3A Power Adapter – Spare brick for routers and Mini UPS

This is a wall adapter that converts AC 100-240V household power to DC 12V at 3A, which is 36W. The DC lead uses a 5.5mm x 2.1mm barrel plug. Listing photos show center-positive polarity.

In Bangladesh homes it is a common spare when the original router brick fails, or when a WGP Mini UPS needs a 12V 3A input so the pack can charge while the router and ONU stay online. Match voltage, current, pin size, and polarity before you plug it in.

Output Rating and Load

The brick is rated 12V and 3A. Devices that ask for 12V at a lower current can draw less than 3A from a healthy 3A supply if the connector and polarity match. Do not use it on a 5V or 9V input, and do not feed a load that needs more than 36W.

A WGP Mini UPS that charges from 12V can use the extra headroom so the pack tops up while the router stays on. LED strips and small CCTV nodes stay inside the rating only if the total current stays at or under 3A.

Connector, Polarity, and Cable

The DC plug is the common 5.5mm outer, 2.1mm inner barrel used on many home routers and Mini UPS packs. Listing photos show a center-positive mark. Confirm the same symbol on your old brick or on the device label before first use.

The DC cable is about one metre. The wall end is a Type A two-pin plug for standard Bangladesh sockets. A loose socket still needs replacement, and the adapter cannot fix a worn outlet.

Protection and Heat

Listed protection covers short circuit, over-voltage, and over-current. Those circuits cut output when the jack is shorted or the load climbs past the design limit. They are not a whole-home surge panel or lightning protection. Unplug networking gear in a severe storm.

Compatibility Checks Before You Buy

Use it only on gear labelled 12V DC that accepts a 5.5 x 2.1mm jack and center-positive polarity, and whose current need is 3A or less. Typical matches on this listing are WGP Mini UPS units, many Wi-Fi routers, ONU boxes, small CCTV power nodes, and short 12V LED runs inside 36W.

A 2.5mm inner pin will not lock. A center-negative device can be damaged. If your old label is missing, measure the barrel or compare it to the old plug instead of guessing. This SKU is a general 12V 3A spare, not a branded exclusive for one router line.

People Also Ask

Will this adapter run a WGP Mini UPS?

Yes, if that pack charges from a 12V 3A input and uses the 5.5 x 2.1mm center-positive jack. Confirm the label on the UPS before you plug in.

Can a 12V router use a 3A adapter?

Yes when the voltage, barrel size, and polarity match. The router draws only the current it needs. Stay inside 36W total if you also feed an ONU or a small camera from the same class of supply.

What is the DC pin size?

5.5mm outer diameter and 2.1mm inner diameter. That is the usual home-router barrel. A 2.5mm inner pin will not seat. Check the old plug against a ruler if the device label is worn.

Is the plug center positive?

Listing photos show a center-positive mark. Match that symbol on your device. Reversing polarity can damage the board. Do not force the jack if it feels loose or the ring sizes differ.

Does it protect against lightning?

No. Over-voltage and short-circuit protection cover wiring faults and overload on this brick. They do not replace a surge protector. Unplug during a heavy storm.
