Cordless tire inflators (or air compressors) are an unusually rare product category as the air compressor market is dominated with lower-cost corded air compressors that, in general, also offer more inflating power per dollar. However, the portability, versatality, and ease of use of cordless tyre inflatora such as the Black & Decker ASI500 is unmatched by corded ones. A cordless air compressor can be used in home settings as well. Black & Decker ASI500 is one of the few cordless tire inflator in the market offered by reputed brands and we give it a try to weigh it usability.
Review Summary: Good inflation performance at a very reasonable cost when compared to most other cordless competitors. Black & Decker ASI500 is our #2 favorite top cordless tire inflator (or air compressor). Only the Campbell Hausfeld Inflator (our #1 recommendation) beats it in performance, value for money, and durability.

What we Like
- Good inflation performance and maximum inflation pressure capability of up to 90 psi
- Dual Functionality of both high-pressure tire inflator and low-pressure inflator for mattresses and toys etc. in one unit

- Can also deflate various inflatables

- Can be charged from an AC wall outlet as well making it an excellent home-use general purpose inflator

- Convenient high-volume hose and nozzles for big inflatables
What we do not like:
- No auto cut-off while being used in high-volume applications
- Inadequate battery life of about 20 minutes and long charging time of 4 hours
