Compatible AC Adapter for S21 Series

This ABLEGRID AC adapter replaces the original charger for S21ESNA, S21ESR, S21ZPM, S21ZPN, S21ZPNA and S21ZPNB models. It accepts worldwide AC input from 100 to 240 volts at 50 or 60 hertz. The package includes the power brick and a mains cable. Over-voltage and over-heat protection are built in.

Buyers Needing Verified Tip Dimensions

This unit suits owners of the listed S21 models who confirm their device requires a barrel-tip connector with matching DC output. It is not for buyers who cannot verify the exact tip size or voltage their hardware demands. Anyone needing an OEM-branded supply or a different connector type should look elsewhere.

Barrel Tip Connector and DC Output Match

The decisive specification is the barrel tip connector size combined with the correct DC output rating. You must match both the physical tip dimensions and the electrical output to your device before ordering. No other specification determines compatibility.

Questions about this item

How do I connect the barrel tip to my UPS and what is the common mistake?

Match the DC output voltage and barrel tip size to the UPS before plugging in; the common mistake is ordering without verifying the tip diameter and polarity.

What maintenance will this charger need over time?

Keep the unit in a ventilated, low-humidity area and avoid placing it on soft surfaces; no user-serviceable parts are inside.

Which protection limit activates first during sustained high-load operation?

Over-heat protection will trigger before over-voltage protection if the adapter runs continuously at full load without adequate airflow.
