I can't return it but the first time I finally got around to using it the plug in for an extension cord does not work. I get an error message. Other ports all work. This is new out of the box. I emailed the company. We will see if they respond. I will buying something else.

This time works okay for portable power; however, the air compression is extremely minimal. It took almost thirty minutes to inflate a simple pool raft. I would not truly it to inflate anything requiring more pressure or even an inflatable mattress.

When it works it functions well, but after only one year it needs to be replaced as the battery inside completely dies, making it useless.

It might be a good option if leaving the power pack in the garage and using it when needed but I bought it strictly to be used on my boat. I do not want a power pack/jumper box that i have to lug back and forth every time I go out on the boat. To be fair, it is left on my boat and I do not check it often but it hasn’t been sitting that long as i just bought it on 7/18/23 and did not put it on the boat immediately. I thought it would be similar to the NOCO battery pack I have in my car but is definitely is not.I went to jump start my neighbors boat today and saw the battery drained to 82%. Even at that percentage charged, it would not start a 150hp outboard motor. I had to use my NOCO Boost Plus from my car which has not been used in at least 6 months (stays in my car), not fully charged as I jumped a car previously but still had enough juice to do the job.The Schumacher is great for powering small items like phones, laptop, electric pumps etc but if that’s all I’m using it for, other power packs would be a better choice. Looks like I will have to check the battery pack weekly even when not in use but more than likely I will just get another NOCO and leave the Schumacher in the garage.

Shuts off after less than 5 minutes use. Thermal breaker? Who can pump up a tire 3 psi at a time and wait 10 minutes in between for it to cool off?

with the 200 watt feature AC, I thought this would give me some TV time at my hunting camp. It wouldn't even start up a 48 Watt TV. 6 watt light bulb worked fine. It was delivered end of Dec 2022 I just got a chance to use it last week. I had it charged up as directed.

Didn't have the plug as needed

Stopped charging and not able to use!

I bought the new air compressor/battery charger because the previous model worked great and is no longer working. This model had great reviews but don't measure up to the previous model. I bought previous model and this model mostly to keep my vehicles tire air pressure correct. If you wanted 32 psi of air, you could set the old compressor/battery charger to 32 psi and when it reached 32 psi of air, the compressor will stop. On the newer model, the gauge is the only way you could know when you reached 32 psi but the gauge is never correct. Its tough for a guy 70 years old to have to get down so low to the ground to read the gauge and when he does, the gauge is incorrect.

Update APRIL 2021: I contacted Schumacher about replacing the hose due to having a hole and not being able to use the compressor and am really disappointed to learn that once the hose goes bad, the compressor can no longer be used and I’d need to purchase a new unit. They also advised me that they won’t even service this because it’s outside of the warranty period. I will not be purchasing another Schumacher product. I’ve used this a handful of times and the compressor is worthless. This is a known issue. I read many reviews on other sites including Schumacher’s and many have posted the same issue with the hose. BUYER BEWAREUPDATE MARCH 19, 2021:I haven’t been driving as much because of Covid. My daughter is homeschooling and I work from home. I’ve been using this product to occasionally jump my car. This week I went to drive my car and had a low air warning come on. I though “no big deal!” I would just use the air compressor feature and put some air in my tire. This was the first time using the air compressor hose. I should have checked EVERYTHING on this product when I first purchased it because the hose has a hole in it and now I’m stuck with a flat tire! The hole is big enough so that it will not fill up my tire. I’m really disappointed that this came to me with a hole in the hose. I’ve only used the battery jump function but will be testing every feature. I’m going to contact the manufacturer to see if they will send me a replacement hose. Test yours before you end up stranded.I purchased this because I went to drive my car the other day after not driving for a month due to having surgery and my battery was dead. Everyone I called was “busy.” I didn’t want to call my emergency road service because they only offer 1 courtesy jump per year. The rest I have to pay for. This worked perfectly. The only thing I didn’t like is that it took 24 hours to charge. So I wasn’t able to just get it out the box and jump my car. Also, it’s REALLY heavy. I had surgery on my shoulder and it was really hard for me to carry this with one arm. The box says it’s 22lbs. I wish it were lighter. I’m going to leave this in my car and only take it out when it needs charging.
