The CYCPLUS portable compressor let me down through trial and error. It's marketed as a rechargeable device but it never seemed to hold its charge for very long. That's a shame, as it was almost useful for my motorcycle tires .One pro is that it was relatively small and easy to store, but that's not enough to outweigh the negatives. Overall, I'm disappointed with its performance and would not recommend it to anyone in the market for tires and wheels products..
