From the top left on the front of the unit there’s the aluminium power button – a short press turns the unit on and a long press turns it off. Then there’s a 12V 10A car cigarette outlet, the 10.8cm touch screen display, and two 230V 2000W pure-sine wave AC outlets. The US version has 6 110V AC outlets. Even with our oversized UK plugs it would have been nice to have had at least one or two extra outlets. And the rubber flaps can interfere with some larger plugs. This UK version is branded PowerOak for some reason – in the US it’s branded Bluetti. Deeno X1500 (1,036Wh): The X1500 did not fare well in our tests. It came through with one of the lowest usable capacity scores we've collected so far at 69.88%, meaning you see about 724Wh out of the stated 1036Wh. For the price, there are better options. Linking the Goal Zero Yeti 3000X to a solar panel produces a complete and outstanding portable solar generator. This can turn the Goal Zero Yeti into a powerful self-sufficient system running at a maximum power output of 2000W (3500W peak power). Fast Charging of the Goal Zero Yeti 3000X Enernova ETA Pro (1050Wh): Moving up a notch, 83% usable capacity and charges 1kW in about an hour and a half. A better showing and about 10 cents cheaper per watt-hour than its smaller sibling.

Geneverse HomePower One (1,002Wh): This unit was the second slowest overall to charge, but did well on its usable capacity rating at 91%. Its display is small, but offers all the standard input and output features you'd want. The AC200P from Bluetti, or PowerOak in the UK is the most powerful portable power station I’ve tested so far. It has a massive 2000Wh Lithium Iron Phosphate battery and a 2000W AC inverter that can power large power hungry devices like heaters, coffee machines, mitre saws and even an electric lawn mower. Or it can power smaller items for hours on end. Enernova ETA 288 (288Wh): Another example of a hierarchy of models where the smaller units underperform, but larger models improve. This unit took about three hours and forty minutes to charge, but did reach about 81% usable capacity. I briefly reviewed the SP120 panels in my video on the AC50S so please take a look at that if you want more information. I also plan to do a round up of all the solar panels I’ve accumulated – the AC200P will be useful to compare them. So look out for that video hopefully coming soon. I’ll add a link on screen and down below if it’s already out.

With enough solar panels and good enough conditions you can charge the unit at a maximum of 700W which is very impressive. That could make it possible to charge the unit off solar alone in 3-4 hours. Unfortunately the minimum input voltage of 35V means that in most cases you’ll need at least two solar panels connected in series, which increases the voltage whilst the current remains constant.

On every unit, as the main function of these devices is to be a battery, we test charge and discharge cycles. First and foremost, this is the most important feature of the portable power stations we test. If they cannot meet our standard here or do not come near what the other portable power stations in this guide are capable of, we will most likely not include them. Q: Can the AFERIY 2001A 2000W portable power station be compatible with solar panels from other brands?

Specifications

As a more practical example I charged the EcoFlow River Max off this car outlet with just under 110W displayed. Testing 12V 3A outputs As well as the power station, there’s one one of the largest AC adapters I’ve come across and an assortment of charging cables including an XT90 to aviation plug, a car charging cable again with an XT90 connector on one end and an MC4 to XT90 solar charging cable. I’ll discuss all these accessories shortly. These cables can be stored in the supplied drawstring bag. It does the job but I would have expected something a little more premium for the price of this power station. There’s also a user manual and warranty card. The design of this power station is also noteworthy. It's compact and portable. The unit is housed in a durable metal casing that protects it from impact and weather. I do find it very heavy to carry around, but for battery this big, it should be expected to be this heavy. When the combined power of 2 solar panels exceeds 500W, the solar panel output power will be limited to within 500W. Please note that the solar panels used should have an output power not exceeding 500W, output voltage not exceeding 48V, and output current not exceeding 20A.
