POWEROAK 400Wh Portable Power Solar Generator Lithium ion power supply for Emergency Camping backup power source with 300W DC/AC Power Inverter,12V Car DC/AC/USB Outputs, Charged by Solar Panel/AC/Car

OK, so I'll admit that I'm a PowerOak fan. I love their stuff. I travel with it and they've treated me extremely well despite the abuse I put them through.We all want power. We all want to watch tv at the tailgate and with that we have to have power. This usually means lugging a heavy, noisy, gas sucking generator out to the tailgate. That has never been my favorite thing to do, but now there is an easier way with what I call the Tesla of generators. The PowerOak 400wh power generator is a solar powered generator ready to take your tailgate to a cleaner and greener level.It can gives you outdoor portable power that can help power lights, phones, laptops, TVs, blenders and much more. It sports features such as surge protection, short circuit protection, temperature control and pure sine wave. To get started you simply charge the generator up at home, as it is essentially a large power station that can store the power and then output it to a variety of energy thirsty products. There is a battery % indicator, along with Input Watts and Output Watts on the digital display panel. The PowerOak powerhouse has 4 USB outputs and 2 AC output to push the power to your devices.When I saw that this had been released, I decided I needed one. Last fall I moved to New England, and over the winter had several friends lose power as a result of winter storms. I decided this would make a decent stand-in until I could decide if I need a real generator or not. I was also planning to use it for camping, tailgating, and the like.Since I'm planning to use this in an emergency, I thought I should put it through it's paces a bit to make sure it wasn't going to leave me high and dry. The first thing I did when it got to my house was plug it in to charge. I'm not sure how long it took; I just left it overnight. The next day, I took it out and started playing with it. I started out easy- I set it out at a BBQ and let people use it to charge phones and whatnot. Then I started ramping things up a bit, and used it to power a boom box.shop light, some string lights on the patio, and then (just to see if we could) a box fan that was in the mud room. The fan was a bit much- while it did run, it wasn't quite as fast as when plugged into the wall, so we decided that was probably the limit. Still, and impressive unit.Over the next week, my wife used it constantly to charge her phone and other small things. I never plugged it back in for a recharge in the entire week.I had originally planned this for emergency power, and boy does it deliver. I also went ahead and ordered the solar panel, but haven't played with that one yet. I'll write something up on it when I do.I've included a few pics, but the bottom line is this: this thing is absolutely worth it.

Real value for money! Great for charging, giving light, running media, while camping. Lasted us, as a family 4 days, before I needed to attach a solar panel to top up the power. Compact and easy to use.

Was after a small mains back-up for use when travelling. The spec seemed OK and it was on offer so I took a chance. Had it a while as I wished to test it in the field. Unit seems solid and well made and does what it says on the tin so to speak. Its not to heavy and seems to have the output/capacity close to as stated. I had been looking at a higher wattage output but found that the prices rise a lot. So i made the compromise that I would use gas for cooking/heating and just use this for lighting, phone charging and laptop/tv. I have some small solar panels and have used the car also for charging the unit. Only minor issue is that charging only occurs when the car is running or the solar is in Full sun. I have a separate 12v dc powerbank and was hoping to add capacity by attaching it as a charge source but there must be a over volt needed before charging occurs . However you can charge at the same time as drawing 240v OR& 24v (see pic- batt not low - just as i took the pic was at bottom of amination -it increses the bars to show charging ) so that could be useful in some instances to extend the use time. All in all worth the monies. if you can not do without you elec kettle, toaster GFG or airfryer look elsewhere but as with everything more performance comes at a higher price.

Ordered this product a few weeks ago,charged it up and everything is ok.Powers my household fan well and will do for about 10 hrs.Have also tried it with my handheld mixer,and it will also power my electric blanket for campingConnecting to a solar panel is easy,you just need a pair of exstension leads,easily to find on amazon.I bought a Renogy 100 watt flexible panel and have tested it outside at 7pm and it was charging at 35/50 watts.I will try it later at midday for max sunlight.Just to be clear,you don’t need anything between the solar panel and the poweroak,just the exstension leads,male to female,,female to male.Since my Renogy solar panel arrived (100 watts flexible) I tested it on the 24th and 25th of June @ 26C midday with a cloudless sky.I was getting 55/60 watts charge in those perfect conditions.There is not one other person in the reviews who mentions solar charging.So don’t expect 100% rendement from a panel even in almost perfect conditions.Therefore I would suggest a 180/200 watt panel,and you can always cover a part of it up if your charging wattage becomes too high.Afterthought.When I charged this with my solar panel it was 80% full so maybe the inbuilt charge controller was only allowing a charge of 60 watts.I am going to buy a multimeter so will test again soon and post the results here.ATTENTION.The Anderson connection on the battery is on the very small side and if you’re using extension cables when charging via solar panel(so you can have the panel in the sun and the battery in the shade or your car)the cables have the tendency to dislocate as they are heavy and put pressure on the connection.You can counter this by laying the battery on its back.Would be better if the connection was more robust,I.e.bigger.UPDATE.I charged this early March 2022 when we had a sunny spell,I hung my solar panel out of the window,connected my shaver,phone and portable fan to the poweroak and charged them all for free,control panel gave charge rate as 65 watts.The Sun was lowish in the sky,13:00 to17:00 but the angle was just right to get a good charge.
