EADP-10BB / 380437-001 / 380637-001 - 10W 5V 2A 4.0mm x 1.7mm AC Adapter Charger for iPAQ

This genuine OEM 10W switching AC adapter supplies regulated 5V DC at 2A through a straight 4.0mm × 1.7mm yellow-tip barrel connector. It features universal 100–240V AC input, integrated North American two-prong wall blades, and a permanently attached DC output cable.

The adapter is compatible with supported iPAQ Pocket PC and Mobile Messenger devices when connected through the correct charging cradle or barrel-to-22-pin adapter. The 22-pin adapter is a separate accessory and is not included unless specifically stated.

The regional -021 assemblies may use a different wall-plug configuration or regional packaging. They are electrically related to the 5V/2A adapter family, but the AC plug and complete assembly should be verified before substitution.

PSC11R-050 appears in some parts databases for compatible handhelds, but it was manufactured in multiple physical configurations. Do not treat every PSC11R-050 as interchangeable without verifying its 5V output, 2A capacity, center-positive polarity, and 4.0mm × 1.7mm DC connector.

⚠️ Critical Connector Compatibility Notice

This adapter has a 4.0mm × 1.7mm straight barrel plug. Matching the 5V and 2A ratings alone does not establish compatibility.

Before ordering, confirm all of the following:

• 5V DC output
• 2A or greater available output current
• 4.0mm × 1.7mm barrel dimensions
• Center-positive polarity
• Correct device-side charging adapter or cradle
• Correct wall-plug configuration for the intended country

Many supported iPAQ handhelds have a proprietary 22-pin charging connector rather than a direct barrel jack. Those devices require the appropriate barrel-to-22-pin adapter between the EADP-10BB power supply and the handheld.

Documented 22-pin charging-adapter references include:

253652-B21, 254089-001, FA125A, FA133A, FA133A#AC3, 383682-001, 383747-001

The 22-pin charging adapter, synchronization cradle, and handheld are not included unless specifically stated.

Do not substitute WA-10F05C solely because it is rated 5V/2A. Documented versions use a larger 5.5mm × 2.1mm plug and are not direct replacements for the 4.0mm × 1.7mm EADP-10BB connector.

✅ Confirmed Compatibility

Compatibility applies when the handheld, cradle, or charging adapter requires regulated 5V DC power and accepts the EADP-10BB 4.0mm × 1.7mm barrel connector. Models with a proprietary 22-pin connector require the correct barrel-to-22-pin charging adapter.

⚙️ Fit Notes

• Confirm the original adapter is rated for 5V DC before connecting this power supply.
• Never substitute a 6V, 9V, 12V, or higher-voltage adapter.
• A replacement may provide more than 2A, but it must remain regulated at exactly 5V and use the correct connector and polarity.
• The adapter’s DC connector measures 4.0mm × 1.7mm; a 5.5mm × 2.1mm plug is not interchangeable.
• Many listed handhelds require a separate 22-pin charging adapter or compatible cradle.
• The 22-pin adapter is not the same component as the EADP-10BB power supply.
• Regional part numbers may have different wall plugs even when their DC output specifications match.
• “Includes power cable” refers to the permanently attached DC output cable; this wall-mount adapter does not use a detachable IEC AC cord.
• Compare the original model number, output voltage, current, polarity, barrel dimensions, wall plug, and required device-side adapter before ordering.
• Disconnect the adapter from AC power before attaching or removing any charging adapter, cradle, or handheld device.
