  • Battery TypeUPS
  • Worldwide AC 100-240V input works across regions
  • 4V DC output matches PHQ-CPU7V4 battery requirements
  • Over-voltage and over-heat protection safeguards connected equipment
  • CE, FCC and RoHS certified for regulatory compliance

What the charger powers

The ABLEGRID AC adapter is built for devices that use the PHQ-CPU7V4 7.4V lithium-ion or lithium-polymer battery. It suits owners of compatible UPS units or portable equipment who need a direct mains replacement. Buyers whose hardware requires a different voltage or tip size cannot use this unit.

Thermals noise and power draw

The adapter accepts a worldwide AC input of 100-240V at 50-60Hz and delivers a DC output through a barrel tip. Built-in over-voltage and over-heat protection limit temperature rise during normal operation. The brick runs silently with no moving parts and draws only the power the connected device requires.

What the bundle changes

The package includes one new AC-DC adapter and nothing else. No cables, mounting hardware or software are supplied. The charger simply restores mains operation for the target device, so users must already have the correct battery and connector on their equipment.

Questions about this item

How do I connect the barrel tip to the PHQ-CPU7V4 battery, and what polarity check do people skip?

Match the centre-positive barrel tip to the battery's DC input; verify the 7.4 V output marking before plugging in.

What upkeep does the charger need after months of daily use?

Keep the vents clear and operate in a dry, ventilated area; dust the case periodically to maintain over-heat protection.

Which limit appears first when the adapter runs continuously at full load?

The over-heat protection trips first, shutting the unit down until it cools.
