Portable Power Station 300W Solar Generator 280Wh(without Solar Panel), 110V Portable Power Bank with AC Outlet Pure Sine Wave, DC, USB QC3.0, External Battery Power Pack for Camping RV Outdoor Use

Product holds a charge for long time than stated in storage. Works great when I used it. Unfortunately, the AC plugs wasn't working and after contacting ZeroKor about the issue, they were very helpful and reasonably replaced the unit even though it was out of warranty. Very satisfied with product and company service support. I have no worries about taking it camping to operator small camping appliances or storing for long periods of time.

I've had this portable power station for a couple of years now and it still works great. I drain the charge and recharge every few months to make sure it's still working. I can't remember what the price was at the time, but I got it on sale and I feel like the quality is definitely worth it. I like the built-in light. Can charge several items at a time and power low W items. So far very happy with it.

It’s a little gadget, right here is worth the money. It’s not gonna power the house, but it’s definitely gonna charge all your phones your tablet your watches your fans air up your air mattress out in the woods is perfect. It takes a little while to charge back up with the solar panels, but it works really good.

Great little battery pack. Does everything you'd want at this size. Battery life is surprisingly great, and long lasting. Only complaint, "which stopped 5stars" the solar panel is absolutely useless. I left it charging in complete sun for 9hrs, only 1 bar..

I’ve tested it a couple times with different things. Battery charged 3 battery packs, go pro & phone fully with only using 1/5 of the Battery energy. The solar panel by itself charges great. I took my speaker, laptop, and DJ board out in a park and it kept everything powered and the solar panel kept the battery charged. The display makes it very easy to see the charge and it’s very easy to use. I’m going to Electric Forest a 4 day camping festival with no power in a group of 4. I’m confident this battery and solar panel combo is going to keep all our devices charged through out the weekend! Great Product for the Price!

So, this thing would be pretty sweet if it came anywhere close to the listed specs.... I love the form factor, it's a nice size... but performance wise, this is HOT GARBAGE! Don't buy this unless you can get it for maybe 50 dollars. -- NOT 300 watts AC! NOT PURE SINE WAVE! One thing you will notice is the AC output says 300 watts MAX. when something says xxx watts AC MAX, that figure is basically meaningless. The only meaningful figure is the continuous output. and for this little jewel that number is less than 100. I have a 15 watt wi-fi router, and it runs that fine with the AC adapter... I have a laptop with a 300 watt dock/power supply (but the laptop only draws 100 watts max when the dock isn't engaged (just pass-through power). When this battery is fully charged, it can barely power my laptop (which generally draws about 30 watts. The laptop becomes glitchy and almost unusable. I QUICKLY unplugged my laptop and i hope it didn't damage it. so basically, what i could determine from this is that this thing provides < 100 watts continuous, and it clearly isn't a pure sine wave either. it can handle a 15 watt adapter, and that's about it. -- DC doesn't work I tried plugging in a car cigarette lighter PD adapter, and also i tried charging a portable air compressor using the 12V dc port (again with fully charged battery pack). the USB PD adapter made the battery pack glitch and turn off instantly (with no load plugged into the adapter). The portable air compressor did NOTHING. -- NOT MPPT i plugged this into a 5 amp 20V solar panel (which is high quality and works very well). I measured the voltage and current several times... so evidently the "maximum power point" according to this thing is... 13 volts and 2.4 amps. that's ALL it ever measured. so... like that's not the maximum power point, by my calculations... that's about 30 watts from a 100 watt solar panel. (and this panel DELIVERS 100 watts in full sun). even if the voltage was held to 13 volts, i would understand.. batteries have certain charging requirements, but the current should have been 5 amps in full sun. pathetic.

Shipped and packaged well. Originally I purchased 1 because I have been wanting a power station that I could use for camping, trips, odd jobs, etc. This power station exceeded my expectations so much that I purchased a second one less than a week later just to catch the deal (reduced price and free bag). When I received the power station it was 3/5 charged. I drained the battery by plugging in a night light that had a lightbulb that was 53w and 800 lumens, a charging station the had an iPhone (5% battery life remaining), AirPods (2% battery life remaining), Apple Watch (0% battery life remaining) and a tablet (50% battery life). It took 8 hours before the power station was completely drained and all products were 100% charged. Total charge time was 6hrs. I used the power station for a day of deliveries (10hrs) charging 2 phones and a tablet and the power station was 2/5 full. The power station is very powerful, durable and portable. It runs quitely. The only time the fan turn on was when the AC option was set and the noise level was minimal. There is a bright light and I appreciate that feature. This is a great investment and I may buy another one.

Used this to go camping and had our sound machine plugged into it every night. It worked perfectly. Lasted all night. Worth every penny.
