Dexpt 120W 19V Charger for Inogen One & BA Batteries

This replacement power adapter is built to supply steady 19V power to many portable oxygen concentrator battery types and compatible devices. Designed as a high-quality alternative to OEM chargers, it combines robust electrical performance with protective circuitry and a roomy cord that eases charging at home, in vehicles, or on the go. The unit meets broad input voltage ranges and includes overvoltage, overcurrent, and short-circuit safeguards to help preserve the battery and adapter during routine use.

Will this Dexpt charger work with my Inogen One or BA-series battery?

The charger is compatible with Inogen One models G1, G2, G3, G4, and G5 and with the listed BA battery packs (BA-301, BA-302, BA-303, BA-400, BA-401, BA-403, BA-408, BA-503, BA-516). It also fits certain Mango and OxyGo models when the battery amperage is equal to or less than 6.32A.

• Output: 19V, 6.32A, 120W — matches recommended voltage for target devices
• Backward compatible with lower-wattage 19V devices (e.g., 4.74A / 90W)
• Check your battery label for voltage and amperage before use

How does the 10 ft cord improve everyday charging?

The extra-long cord gives you flexibility to plug in farther from wall outlets or vehicle sockets, so you can position the device where it’s most convenient without strain. This is particularly useful in tight spaces, when sitting at a desk, or when using a rear car outlet.

• 10-foot length reduces the need for extension cords
• Easier placement of device and battery while charging
• Less cable tension on connectors — smoother, safer connections

What safety protections and build quality does this adapter offer?

Dexpt engineered this adapter with multiple protective circuits to limit the risks of voltage spikes, excessive current, and short circuits. The adapter is constructed from durable components to provide consistent output and a long service life comparable to factory replacements.

• Overvoltage, overcurrent, and short-circuit protection built in
• Wide input range (100–240V) for global use with appropriate plug
• Premium materials and tested performance for reliable power delivery

What’s included and what warranty covers this charger?

The package contains the power adapter and an AC power cord, ready for immediate use out of the box. Dexpt backs this product with a one-year manufacturer warranty for defects in materials and workmanship, giving added confidence with your purchase.

• Package: 1 power adapter + 1 AC power cord
