  • Worldwide 100–240 V input for universal compatibility
  • 50–60 Hz frequency range matches global mains supply

Power adapter for 9 V devices

This ABLEGRID AC DC adapter delivers 9 V at 4 A through a 5.5 mm by 2.5 mm barrel connector with reverse polarity and a negative centre pin. It accepts 100 to 240 V AC input at 50 to 60 Hz for worldwide use and includes a 1.5 m cable. Over voltage and over heat protection are built in.

Replaces a lost or faulty 9 V 4 A supply

The unit substitutes an original charger that matches the same voltage, current, connector size and reverse polarity arrangement. The upgrade is worthwhile when the previous adapter has failed, the tip no longer fits securely or the cable is damaged. It is not for devices that require a different voltage, a higher current rating or a standard polarity centre positive tip.

Check voltage polarity and connector fit

Verify that the equipment label specifies 9 V DC, 4 A or less and shows a negative centre pin symbol before ordering. Measure the barrel dimensions against the 5.5 mm outer and 2.5 mm inner diameters shown in the product images. Ensure the device power port accepts the reverse polarity plug and that the 1.5 m cable length reaches the intended outlet.

Questions about this item

Does the 5.5 mm by 2.5 mm barrel plug have the centre pin wired as negative?

Yes, this adapter uses reverse polarity with the centre pin negative, matching the specification shown in the product title and images.

Can I plug this straight into a UK wall socket without an adapter?

No, the unit comes with a US mains plug, so a separate travel adapter is required for UK sockets.

How long is the DC output lead, and is it replaceable?

The lead is 1.5 m (5 ft) long and is permanently attached to the adapter body.
