Manufacturer description
The NEEWER 1-Channel 48V Phantom Power Supply solves the single most common problem new condenser microphone owners hit: your mic needs 48V and your interface or mixer doesn't supply it. This compact single-channel unit sits in-line between your microphone and your mixer or sound card, delivering steady 48V phantom power through balanced XLR input and output jacks. The universal XLR wiring means it works with essentially any condenser mic and recording setup, and NEEWER includes an 8-foot XLR male-to-female cable plus the power adapter in the box, so you can wire it up the moment it arrives…
SpecPicks Verdict
SpecPicks scored Neewer 1-Channel 48V Phantom Power Supply with Adapter using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. NEEWER's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Does this come with the XLR cable, or do I need to buy one?
One 8-foot XLR cable with male and female connectors is included, along with the power adapter. You may still need a second cable to reach your mixer depending on your layout.
Will this work with my condenser microphone?
It uses universal XLR input and output and delivers standard 48V phantom power, so it works with condenser microphones and recording gear using XLR connections. Confirm your mic accepts 48V rather than a lower voltage.
Is the microphone included?
No. NEEWER states explicitly that the microphone, pop filter, mic stand, and 1/4-inch male to XLR female cable shown in the product images are not included. You get the phantom power unit, one XLR cable, and the adapter.
How many microphones can I power with this?
One. This is a single-channel unit with one balanced mic input and one output. For a second condenser mic you would need a second unit or a multi-channel supply.
How do I know it is actually powering the mic?
The unit has an on/off power switch and an LED indicator that lights when power is on. If your condenser mic still produces no signal, check that the mic is on the input jack and the mixer is on the output jack, not reversed.
