Good value, sturdy, works well for bike tires and car tires. Love the battery power. I ran it too long and it shut itself off to cool.

I was concerned about battery life after reading somd reviews. After sitting for 3 or 4 months after the first use, the pump had plenty of juice. I did have the battery separated from the pump in the case it came with. The only reason I gave 4 stars instead of five are because of the straps in the case. They are a nuisance to deal with as the velco keeps reconnecting due to the stiffness of the straps. The pump is easy to use.

I have owned a few portable air pumps and so far this is the only one that has an accurate gauge. Most of the other units that I have had or as far as 3 to 4 pounds of pressure low so it inflating my car tires to 36 pounds. My car would show the tires were inflated to 40. The auto shut off feature is very nice to ensure that the tire is not overinflated and the portability of this unit is great and allows me to bring the compressor to the car and not having to use my large compressor just to fill a car tire or bicycle. The build quality looks to be durable and very compatible too the brand name portable air pump. The other area that I was pretty impressed with was the fill rate this unit seems to air my tire up any much faster rate than any of the other ones that I have had and the battery so far has been quite impressive at hell long it does last the last portable air pump that I had would be almost completely exhausted after just going around and topping off the tires on my car. When I receive this unit, first thing I did was charge the battery to make sure that it was fully charged, which is what you should do even though it does come with a charge in it. It is always best to top it off before the first use to ensure maximum battery life. Once the unit was fully charged, I took it around to all my cars and trucks to check all the tires and the battery did not run down at the same rate as the smaller portable unit that I have. The fact that this is a dual power unit that can be powered by the battery or plugged into the lighter of your car. Makes this a great emergency tool to have with you when you’re taking road trips for me I always take a portable compressor and a portable jumpstart pack when I am traveling just in case an emergency situation comes up or if I encounter someone who is having a problem, I am prepared to help. The only thing I wish that they would do would be to include a second battery not that it needs one, but it would be nice to always have a second battery fully charged as a back up. For the price of this unit compared to the price of the brand name, but this is designed after this is definitely one of the better buys that I have made. A lot of times they say you get what you pay for and in this case, I think you get a little more than what you pay for. As far as noise level, this unit is about typical or a small portable air compressor. It is by no means loud, but just like any other air compressor. There is going to be a certain level of noise associated with the air pump. If you were considering buying a portable battery powered pump in my opinion, this is one to buy. I stated earlier in the review when inflating my tires to 36 pounds and checking it against the car’s computer. The car reflected exactly the same pressure as the Phil Gage and my Auto shut off point which was quite impressive. Hopefully this will help someone in making a decision but yes, in my opinion this is a great solution for a battery powered pump and hopefully it will have longevity to the compressor and does not wear out as quickly as some of my others

I got this on sale and someone I knew had it and I love it! I can just plug it into my car and use it when I need to. It’s very easy to use and you don’t even have to hold it. It does get very loud and hot after a while but it does a quick and good job of pumping up tires. And now I can pump up my tire when I need to without having to go somewhere and pay money to do it. Buy this!!!
