PowerOak 2400Wh Portable Power Station EB240, Lithium Battery Pack Solar Generator with 2x230V/1000W Pure Sine Wave AC Outlets, 45W PD, Backup Power Storage for Home Emergency, Outdoor Camping

Update 25/6/2020So I received a new mains adapter direct from the factory. The customer service was very good and I have given the product the 5 stars it is worth.So I am giving this 4 stars at the moment - as the unit arrived with a faulty mains adapter that didn't work at all. The customer service was good and they have promised to send me a replacement charger from the factory. So I will update the review once this has been received - giving the unit 5 stars or 3stars or less if the adapter doesn't arrive etcSo my review of the unit is below -The EB150 seems to be branded as Maxoak in the US and Poweroak in Europe. If you check out the many US YouTube reviews for this product you will see that it comes very highly rated. In Europe where we have much less choice in the solar generator / all in one power bank market it is the best on the market.Although it does have some limitations that you should keep in mind.For people that love camping or caravan holidays - or perhaps you live in an RV or a canal barge, this unit will be perfect for you. You will already understand what you can power with 1000watts and will probably have a 12v efficient fridge already.The EB150 is a quality product, it uses 4 LG car grade batteries that are good for more than 2000 cycles. You get a built in quality 1000watt sinewave inverter and MPPT charge controller that allows you to charge at up to 60volts - 10amps.It's equivalent to around a 120ah 12volt battery, but in reality since you can only really discharge a quality AGM battery to 50% you are actually getting the equivalent of a 240ah AGM leisure battery or a 120ah lithium battery.The unit can be fully discharged and cycled at least 2000times - keep this in mind as even the best AGM batteries will only discharge 40-50% and cycle 300 to 400timesI should add that the 12volt output is regulated - so as the unit discharges it still outputs more than 12volts.So at the price this is sold for you can't purchase a quality 100ah lithium battery, 1000watt sinewave inverter and MPPT charge controller to make your own set up.So the limitations come when you want to use this around the house as a back up power supply for say power cuts.It will power the TV or computers just fine. I have even had mine running the oil fired central heating and it will do this for days.You will struggle with the 1000watt inverter to power the average household fridge freezer. Most standard 240v fridge freezers use a compressor that everytime it starts creates a power surge for a second that can be over 5 times its continuous rated consumption. So a fridge freezer that is rated at 300watts, could need 1500-1800watts to start.I have tested the EB150 on around 6 different fridges and a chest freezer and it couldn't power any of them effectively. I even have a Bosch inverter fridge freezer (rated A+++) which has very low power consumption and for some reason the fridge worked, but the freezer defrosted over the 6 hour trial.In the end I decided for my power back up requirements that I would purchase a 12volt ultra low consumption 166L freezer and separate 12volt 100L fridge - the kind of units sold for off grid living. These work beautifully. I have two EB150s and I can power the fridge and freezer for up to 4 days without sun light on the solar panels.With the mains charger the unit is charged from empty in under 9 hours (168watts) - I live in Spain and 300watts of solar charges the unit in under 6 hours. The EB150 will accept any charge of up to 60volts DC and up to 10amps, so in theory you could have 450watts of solar or an aftermarket mains adapter (think 54.6volts - 7amps) that charges the unit much quicker into the 7.9mm socket.
