## Questions & Answers

**Q: how long would this run a 12v/240v caravan tv for**
A: It's got an advertised capacity of 500Wh, if your tv draws 50W then it'll do 10 hours.

**Q: To the seller, please confirm that the uk version i've just ordered has a 230v output rather than the usa's version at 110v.**
A: hello valued buyer,
Yes,it's the UK version which is 230v output,sorry for the misleading information of the A+ page,we have updated it,while amazon will takes some time to ajust it.
thanks,
Niki

**Q: How many ways can i charge this powerhouse?How should i choose a suitable solar panel?**
A: You can charge it with a solar panel of up to 120 watts.
You will need to buy a pair of extension cables as the one that come with this are about 12” long,and the ones connected to your solar panel will be shorter.Just connect the m/f and f/m to the battery cable and to the solar panel.You don’t need anything in between as it’s built in.
The sun must be shining and your poweroak turned on before it will charge.Sounds straight forward but no one explained this to me and someone even said  he could not find the cables to connect it,which is complete rubbish,and made me decide to ask for a refund,which I have since cancelled.
Hope this helps.BTW I have it connected to a renogy flexible 100 watt panel.Also a renogy tool for releasing the clips or long nose pliers as they are to small and stiff to release with your fingers.

**Q: if for my freezer of 228w  is it okay to use it, how long can the power last? 1 ,2 4 hours?**
A: How long this power station can power your freezer mainly depends on the power consumption of your freezer. You can check the specification of your freezer or consult the freezer seller to get the freezer's daily power consumption in the unit of KWh (kilowatt hour). Then you can calculate how long our solar generator can power your freezer. For example, we have checked that a houshold freezer with rated power of 140W usually consumes about 0.85KWh / 850Wh energy in 24 hours - in other words, it consumes about 0.035KWh / 35Wh energy per hour. Considering the depth of discharge (DOD) of the battery and the conversion efficiency of the inverter (total about 80%), the actual usable battery capacity of our AC50S 500Wh power station is about 400Wh. So the AC50S power station can power the above mentioned 140W freezer for about 11 hours: 400Wh ÷ 35Wh = 11.

### ⭐⭐⭐⭐⭐ The Tesla of Generators!
*by A***A on 3 March 2019*

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.

### ⭐⭐⭐⭐⭐ Value for money
*by M***E on 18 September 2024*

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.

### ⭐⭐⭐⭐ Small and Handy Power backup
*by D***S on 6 August 2024*

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.
