EnginStar Portable Power Station 300W 296Wh Battery Bank with 110V Pure Sine Wave AC Outlet for Outdoors Camping

Been working great so far. We haven’t had full sun since I bought it, but it still charges with the solar panels, just slower. I’m sure it’ll be much faster in direct sunlight. I was also surprised how big the solar panel was, and it easily folds up to a smaller size for storage and travel. It comes with lots of adapters. Has AC outlets, USB-A, USB-C, and other ports for charging different devices. Overall, very happy with it. Read more

My main goals out of the purchase of this Portable Power Station were as follows: 1. Ability to power a portable refrigerator/freezer for at least 5 hours 2. Affordable 3. Needed and Auxiliary port (Cigarette lighter port) 4. Could recharge via solar 5. Lightweight My star rating is based on the unit’s ability to meet my requirements. With that being said, this unit easily checked all those boxes. This is a great unit at a very affordable price. When determining what size of a unit you need, just divide the wattage of unit by the wattage of the device it is powering. Example: My refrigerator/freezer draws ~40 watts per hour, 296/40 = 7.4 hours of run time (this is approximate only) Pros: 1. Very affordable price 2. Very light and compact 3. Was able to run my portable refrigerator/freezer cooler for 6+ hours 4. Easy to use 5. 3 ways to charge, solar, DC and AC. Cons: 1. Not LifePo4, standard Li-ion 2. Nowhere to store charging cables. Something as simple as a little bag with a Velcro strap that you could attach to the handle would be helpful to keep those cables from disappearing. 3. The state of charge gauge is lacking a little. Shows a symbol of a battery that has 5 blocks in it. I think adding a percent state of change would be a lot cleaner. 4. Max solar and AC charging is ~60 watts. 5. Limited USB-C wattage (18 watts) Read more

It's great power bank for the price. Smaller than I thought. Supports samsung Super Fast Charging 2.0 and over 120w input power! It's not that heavy it feels like it's pretty good quality. The built-in light is a great feature, as well as the battery technology inside this little power bank Read more

Took a gamble on this as we were going off grid camping and needed something to power my Airsense 10 cpap. From reviews it was recommended to turn off humidifier, which I did. I have to say my worries were gone. After two nights of 7-8 hours per night, o ly one bar was used. Based on that I can go 3-4 nights wirh my cpap. I did try to see if it would power our single serve Keurig. Although coffee maker powered on, it shut off prior to brewing. We think it couldn't support the load. This doesn't impact my review as I bought it to support my cpap and it exceeded expectations. Read more

I order from Amazon all the time, but almost never write product reviews. But I felt the need to write a review after having this machine for a little more than a month. I did quite a bit of research before purchasing this. Over the course of a few weeks, I probably looked at somewhere around 100 of these. I had very specific requirements when it came to what I needed this for. This has exceeded my expectations and then some. It takes a little while to charge. I haven’t tried it with solar panels but I have use the cigarette lighter charger and the wall charger. It comes with both of those cables it does not come with solar panels just to be clear.you have to buy those separately. But I must say I use a hair straightener with it. As well as various other devices. I like how you can see in real time exactly what the wattage being used is of each device like on my straightener it tells me in real time what why did just being used. It shows the surge when you first turn it on and it starts heating up. And then immediately starts to fall down to the 25 walks that it says on the straightener. I can use my hair straightener. Can it can charge my phone and my car vacuum and the battery only goes down like a bar. You can use it while it’s charging as long as the wattage that you’re trying to output is less than the wattage that is being taken in. Meaning it will tell you how many watts is going into charge it which is about 60 so as long as you are using less than that, it will charge as you’re using it which was one of my requirements actually when I was looking at these things. I could go on and on about the different features but all in all I’ve been using this for about a month now almost daily and I must say I am so glad I bought it each time I use it I know I made the right choice. It is only 300 W so you’re looking for something to power a lot of stuff this isn’t the thing for you but on a day-to-day basis to do the things that I needed to do it does effortlessly I hit a home run with this little machine.

This is one of the best investments anyone can make. I've had this power station for over a year now and I've used it fairly consistently. It holds charge well and is quite portable enough to hold in my backpack. I've charged my phones, fans, laptop and used my lamp on it for the entire night and in the morning I'm still looking at half of battery life remaining. The lamp is really bright. It is pretty easy to use by simply turning on the power station by the power button and you'll be able to use the USB ports you charge. Switching to AC is also easy with a simple press of a button. It doesn't charge as fast with the solar panel but I'm thinking it's the wattage of the panel. However, because it keeps charge so well, many times I'm putting it to charge with half the battery charge which decreases the time I need for full charge. Read more
