Review: Reliable Power When You Need It Most! - I purchased the PowerSmart 2500 Watt generator and couldn’t be happier. From the moment it arrived, setup was straightforward and easy to get it up and running. It’s compact yet powerful, perfect for home backup, camping, or powering tools in remote locations. The generator runs smoothly and quietly, and I was impressed by fuel efficiently. The build quality feels solid, and it started up effortlessly right out of the box. I’ve already used it during a brief power outage and it kept my essentials running without a hitch. Plus, the price point is unbeatable for the performance it delivers. Highly recommend this generator to anyone looking for dependable, portable power. Great value, great product!
Review: Price was on point! - The Power Smart 3800 generator works great for camping, which is what I got it for and running my furnace during power outages. I only plan on using propane. Which was the biggest selling point. So I can only comment on the operation with propane. But I’m sure it works just as well with gas. It was easy to start. The noise level was low and on par with other generators at the beach camping. Very easy for one person to move around. Overall very happy with my purchase

## Questions & Answers

**Q: Can this be used for car detailing vacuuming extractor use??**
A: Yes

**Q: Can this power the refrigerator and microwave?**
A: You only have 1900 watts
If is a medium size or small refrigerator is good
 If you look in the back of your refrigerator and microwave is going to show you how many watts does it need 
If it only shows amps  
Do the following 
Example:
115v.      Amps 8

115
  X8
920

You total wattage is going to be 920

**Q: How loud is the device during operation? Will running at night disturb the neighbors?**
A: no - don't do what another responded.  Never install a portable generator indoors, even in a garage and even if exhausted.  Never indoors under any circumstances.

**Q: Will it run on 50/50 methanol/water mix?**
A: It says pure gasoline was recommended. I would guess a 10% alcohol 90% gasoline would also. It is a 4 cycle and you DO NOT mix oil in gas. This is made for the North America market!

### ⭐⭐⭐⭐⭐ Reasonably priced and sized as a backup power option - includes propane hose
*by R***N on March 24, 2026*

Just received this generator a few days ago. I bought it as a backup in case of power failures so I can run a refrigerator, a few electronics, and recharge devices. I’ve put oil in it and started it on propane and it seems to work great. It is not too loud, can be moved relatively easily, and is a good size to run a few key items (though of course it won’t power a whole house). It does come with a propane hose and regulator; I’m mentioning that specifically because there is some inconsistency between what’s listed here and what’s in the manual. It also came with a small oil funnel and spark plug wrench.
