Five-pack AC adapter kit

This Amamax kit contains five identical wall-mount power supplies, each delivering 5 V at 2 A through a 5.5 mm x 2.1 mm barrel connector. The pack suits installers or IT teams who need multiple spares for routers, modems, LAN phones or similar office devices.

5.5 mm x 2.1 mm centre-positive plug

The single specification that decides compatibility is the barrel connector size: 5.5 mm outer diameter and 2.1 mm inner diameter with centre-positive polarity. Only devices that specify this exact plug will connect securely and operate correctly.

Universal input with full protection

Each unit accepts AC 100–240 V at 50/60 Hz with a 0.5 A maximum draw, so it runs cool on any mains supply worldwide. Built-in over-voltage, over-current, short-circuit and over-temperature protection keeps the adapter and connected equipment safe during continuous use.

Questions about this item

What does the 5V 2A output actually deliver to a connected device?

The adapter supplies a regulated 5V DC at up to 2000mA, so a router or modem drawing within that limit will receive stable power without voltage sag.

What does the AC 100–240V 50/60Hz input rating mean for daily use?

It accepts mains voltages from 100 to 240V at either 50 or 60Hz, letting you plug it into standard wall outlets worldwide without a separate voltage converter.

Will the 5.5mm x 2.1mm barrel plug fit my equipment?

The centre-positive 5.5mm outer by 2.1mm inner barrel matches the common jack on many routers, modems and office devices; verify your device’s jack size before connecting.
