708 owner reviews, more than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The ONEAND P739 stands apart from most other battery-powered entries in this category because it includes a published tank capacity: 1 gallon. Running on 18 volts, it gives buyers a cordless option that can store a small air reserve rather than inflating strictly on-demand. Dimensions are listed at 13.5 inches long by 11.5 inches wide by 10 inches tall, making it a compact but not ultralight unit.
At $152.99, the P739 is priced above many pure inflators but below the corded 6-gallon options. With 708 reviews and a 4.5-star rating, the review base is smaller than top-demand peers, but the satisfaction level is strong. A rate of 100 units bought last month indicates consistent, if modest, ongoing demand.
Buyers who need true tank storage in a cordless format will find few alternatives in this price range. The tradeoff is that 1 gallon limits sustained use, and the 18V platform compatibility must match existing batteries for the setup to make financial sense.
Pros
- 1-gallon tank sets it apart from pure inflators by providing brief air storage for light air tool tasks
- 18V battery-powered operation removes the need for a power outlet
- 4.5-star rating from 708 owners shows strong satisfaction for its intended use
- Compact dimensions at 13.5 x 11.5 x 10 inches suit tight workspaces
- $152.99 is competitive for a cordless compressor with a tank
Cons
- 1-gallon tank limits sustained air tool use; a full nailer session will cycle the compressor frequently
- 708 reviews is a thin base compared to higher-demand models in this category
- 18V platform compatibility must align with existing battery inventory to avoid extra battery cost

Performance notes
The ONEAND P739 runs at 18 volts battery-powered and carries a 1-gallon tank. No weight spec is published in the listing data. The 1-gallon capacity is adequate for inflating tires, occasional brad-nailing, or brief air tool bursts, but owners running continuous nail gun work will notice the compressor cycling more frequently than a 3 to 6 gallon corded unit would. At 13.5 x 11.5 x 10 inches it fits in truck beds and tight job site corners comfortably.
What buyers say
Owners report satisfaction with the cordless convenience and the practical benefit of having even a small tank for intermittent nail driving. The main points of critique focus on run time between battery charges during heavy use and the recharge cycles on extended jobs. Buyers who use it for inflation and light tasks rather than sustained air tool work tend to leave the most positive feedback.

Frequently asked questions
What 18V batteries are compatible with the ONEAND P739?
The listing specs confirm 18-volt battery-powered operation, but do not name a specific brand battery platform. Check the current product listing for compatibility details before purchasing if you plan to use batteries from an existing tool kit.
Can the ONEAND P739 run a framing nailer or impact wrench?
A 1-gallon tank can support intermittent use with brad nailers and small finish nailers, but framing nailers and impact wrenches typically need a larger tank for sustained use. The P739 will cycle its compressor frequently under heavy demand.
