20 W USB AC adapter delivering 15 V at 1.33 A for compatible HP tablets and laptops

  • Delivers 20W power for HP ENVY X2 tablet

  • Works with 100-240V input for worldwide use
  • USB plug design fits multiple HP part numbers

HP ENVY X2 compatible charger

This 20 W USB AC adapter delivers 15 V at 1.33 A for the HP ENVY X2 tablet and laptops using part numbers such as HSTNN-DA37, HSTNN-CA37 and 714148-001. It ships with a detachable power cord and accepts 100-240 V 50-60 Hz mains input. The CE-marked unit replaces the original factory charger for the listed models.

Replaces lost or faulty 20 W USB units

Swap this adapter in when the original HSTNN-DA37, HSTNN-LA37, TPN-P104, 735744-001, 735800-001, 714148-002, ADP-20EH B or PA-1200-22HB charger is missing or damaged. The jump is worth it only if your device requires exactly 15 V 1.33 A over a USB connector; higher-wattage or barrel-plug units will not fit.

Limited to 20 W USB power delivery

The USB output caps usable power at 20 W, so devices needing more current or a different voltage cannot charge from this brick. It operates on 100-240 V 50-60 Hz mains but provides no data lines or fast-charge negotiation beyond the fixed 15 V rail. Buyers whose hardware draws above 1.33 A or uses a proprietary barrel jack must look elsewhere.

Questions about this item

What plug size does the Graviton 15V 1.33A 20W USB AC Adapter use for the device connection?

The adapter uses a USB plug for the output connection to the device.

How do I install the adapter, and which step is often missed?

Connect the supplied power cord to the adapter, plug the cord into a 100-240V 50-60Hz mains socket, then insert the USB plug into the HP ENVY X2 or compatible tablet; the step often missed is ensuring the power cord is fully seated in the adapter before switching on the mains.

Which replaceable part will need attention first on this adapter?

The detachable power cord is the only user-replaceable component; the adapter body itself is sealed and not serviceable.
