Portable Power Supply,Small Portable Power Station 300W 288wh,110V Pure Sine Wave AC Outlet,Li-Ion Battery Mobile Power for Outdoor Camping/Travel/RV/Home Backup/Emergencies

A present for my Mom and I'm so happy with the outcome. I charged it fully and then took it to her. We connected her t.v. to it for a test and let it play for an hour. The bars never dropped, but then it is a small t.v. We were all giggles with excitement, this is what's most important to her when she loses power. Awesome buy!

I tested charge and discharge several times after receving. I last 5.5 hours with a 68 W fan to refresh air in 110V. Very good build quality. Exceptional product for the price. There is even a little fan that starts once in a while after a long use to keep fresh battery and only adds little noise for several seconds.Even the plugs are strong and fine, there is even a wireless charging on the top.Only little "negative" point - the charger is 30W only. That means 8-14hours to charge fully.Overall, excellent feeling, used already a couple of times during electricity failure at home, and works really fine!

I’ve only used it once but it worked great with no issues. The price was very reasonable is the only reason I bought it. Tried it on our tv in our travel trailer. I carry an inverter for power supply when camping off grid and wanted something that I could use for short uses without having to go outside and turn off my inverter. The battery lasted 2 1/2 hours. Takes about six hours to recharge. Small and very light weight. Didn’t use the light that’s that’s built in to it.

I was surprised at how well this cute little battery performed. It arrived with 40% power and I charged it to 80% so that I could test it as quickly as possible. It takes a long time to charge. The screen shows it charging at 30 watts or less and the wattage decreases to less than 10 watts after it reaches 80% charge. I’m assuming that it would probably work well with solar panels as a result. The charging port appears standard, so it probably wouldn’t be difficult to find chargers that would fit. The charger that comes with it gets warm on and off, but that’s normal and it’s addressed in the manual. The display shows 100% before it’s fully charged, so you need to wait until the bars stop blinking. It shows the 100% after it reaches 80%. It also shows how many watts are being used while it’s providing power. I tested it with a Honeywell tabletop air purifier the first time and it drew between 25 and 31 watts, depending on speed used. It’s the black model that uses G-type filters and it moves air well. I let the battery power it on high speed, drawing around 30 watts for six hours and it used approximately 60% of the available battery’s power. I recharged the battery to 100% and tested it on a different brand of air purifier the following day. My Hamilton Beach True Air tabletop model uses 30 watts at high speed, 14 watts at medium speed, and only 9 watts at low speed. I tested this one at medium speed, drawing 14 watts for nine hours. It used 40% or less of the battery’s power, so this battery should be able to power that air purifier on medium speed for approximately two nights during a power outage. I could wear a mask during the day if necessary, but I ordered another battery just in case. Unfortunately, this brand of battery was not available for reordering at the time. Otherwise, I would have happily ordered a second one. It’s quite small and lightweight. It would be ideal for using on car trips or in situations where you might need to charge phones or computers. It’s too small to power large appliances. My Honeywell tower air purifier uses twice the power of the tabletop model, so it wouldn’t be able to run as long using a small battery. For power outages, people can learn to adjust to their circumstances and they can get by on what’s available if they’re willing to be patient while waiting for power to be restored. As far as camping goes, this battery was affordable enough to buy several. I would rather have several small, inexpensive batteries than one large, expensive one. That way, I will have backup in case of a battery failure. And if I used solar panels, I could use one while the others were charging. Batteries like this need to be maintained or they will perform poorly. Most instructions say to charge them to capacity every three months. Smaller ones are easier for seniors and women, especially when they need to be moved around often.

I charged it to %100. With the portable power supply only providing 67 watts of power, to a power hungry Acer laptop, the unit would turn itself off after a few minutes. It's advertised as being able to provide 300W of power. This was about $90 where the other cheapest 330W unit was about $140. Given the price, I assume it's actually only designed to provide power for small devices, such as phones. I didn't test it with anything else, since the power supply meter told me it was only providing 67W.

I have a couple power stations that I use for charging extra batteries at the flight field or for a backup power supply when the power goes out ( I live in Texas so that's definitely a when, not if).So, I'll start with the pros of this model:* It performed to it's stated capacity. I plugged a fan in that was drawing between 51 ~ 53 watts. It ran for 5.25 hours before it cut off.* It stayed cool the entire time and the fan only came on for short bursts.So, now the cons.* The power meter only states the percentage left as 20%, 40%, 60%, 80% and 100%. It's a digital display, so I'm not sure why they wouldn't give more fine/accurate measurements.* The display shows you how much power you're currently pulling, but there's no display of how long it can go at the current rate. This makes it up to the user to calculate.* It takes a long, long time to charge. After I ran it down for the initial test, it took 9.25 hours to charge back to 100%* It requires an external brick to charge so it's one more cord to keep track of. Unlike my other power supplies that use a standard computer power cord.* The max rate it can charge at is 26v x 3amps = 78w. The supplied charger is 45w. Even at 45w, the charger was only charging at 39w, sometimes as high as 42w* Has an icon on the top of it that would make it seem like it has wireless charging, but there's no indication of it in the manual, nor did it seem to have the capabilityAs far as performing as a very basic power supply, I think it works as expected. For a few dollars more, you could probably get a better unit that would be more informative about the amount of power left and the expected runtime, a faster charging time, and a standard power cord.

This worked so well! We used this at a beach bonfire and have decided to keep it…even though I had thought about returning it, I’m glad I didn’t! It worked for our huge speaker during karaoke!
