About this deal

The display is bright and actually shows useful information including time left till discharge – very useful – we even confirmed the accuracy in our full review (see video below). Unlike the EcoFlow this AC200P doesn’t have a UPS function where it can run off mains directly and then switch to battery in the event of a power outage. But it does support pass-through charging so you could use it in a similar fashion to power essential items whilst plugged into the mains and then the fully charged battery would power these items if the power goes out. This wouldn’t be ideal longer term for battery health but I used it like this to plug in all my broadband and WiFi equipment when we were having regular power cuts recently. I’m pleased to finally test a power station with a Lithium Iron Phosphate (LiFePo4) battery which should last a lot longer than your standard Lithium Ion battery. I can’t confirm the battery’s longevity but in my capacity tests it fared well – at least in line with Bluetti’s claims. Although the battery isn’t replaceable and it does contribute to the weight of this power station. It is very heavy which is a real consideration if you need to move this around a lot.

I needed to find some fairly hefty equipment to really put this inverter to the test. I started off mowing the lawn with this 1500W Flymo lawnmower which worked fine. Batteries are typically the single most expensive component in your build, so it’s important to choose the heart of your electrical system wisely. Shop Batteries The 230V mains power is supplied from an internal pure sine wave 300W inverter, meaning the unit can power up to 2 mains power products with a total wattage under 300W. Campervan electrical systems can be confusing. There are so many options that it’s easy to spend days researching and still not feel confident. Our service makes off-grid energy simple. With 500Wh power storage,it can provide you stable power in any emergency situations, charging small devices under 300W like laptops, phones, tablets, cameras, drones, etc.Working time = 500Wh* 85% / rated power of your device For reference, assuming the device features rated power 60W (might be a laptop), the working time will be 500Wh*85% / 60w=7hrs (Estimated time).

BLUETTI AC50S (EU version) 500Wh/300W Portable Power Station - Keep Your Gears Running, Indoors And Out. With the load tester it ran happily at the full 25A drawing over 320W according to the LCD display, although I did find the cable started to get a little warm. Unfortunately there’s no app to monitor or control the unit which would be particularly useful outdoors where the display is very hard to see – especially in bright sunlight. The small font used on the home screen doesn’t help matters. . Charging Unlike nearly every power station I’ve reviewed, there’s no torch on this unit. I would have liked a floodlight like on the smaller AC50S and looking around the power station there appears to be plenty of space to include one. But there are 2 useful 15W Qi wireless charging pads on top of the unit.

The AC200P is the most powerful power station I’ve tested so far. It will power most household items quite happily and it even ran some pretty heavy machinery in my workshop. It’s worth remembering though that at its maximum 2000W output the sizable 2000Wh battery will still only last just under an hour. 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. For example, assume your power of device is 60W, working time will be 2400wh * 0.85/60W=34 Hrs ( rough calculated ) High Capacity 500 Wh Power Station】PowerOak AC50S built in 500Wh lithium-ion battery cell with over 1000+ life cycle, providing plenty of power for various devices such as laptops ( 60 W, 7-8 times), smartphone ( 7 W, 50 times), car refrigerator ( 45 W, 9 Hrs), C-PAP ( 60 w, 8 Hrs), etc. Prepared for any unexpected power outage for indoor and outdoor. As a more practical example I charged the EcoFlow River Max off this car outlet with just under 110W displayed. Testing 12V 3A outputs

You need to turn on the DC subsystem by tapping on the DC icon on the home screen. Starting with the 12V 10A car standard car outlet I wound up the current to the full 10A without any issues – the output on the LCD was around 135W. As I went over 10A the voltage dropped and then the DC output shut off with a DC Output Short Circuit fault not the Over Current fault I would have expected.If that’s not enough for you then you could also try their flagship AC200Max model which we recently reviewed – it has a 2.2kW inverter and 2048Wh of capacity! If you plan to use this powerbank as your primary source of power, we’d definitely recommend purchasing a portable solar panel so you can recharge off-grid. The form factor (case size) is exactly the same between the Delta and the Delta 2, and so is the 1800W of power which can be supplied to your gear. The main change to the newer model is the battery technology which moves from standard lithium-ion to the safer and much longer lasting lithium iron phosphate (LiFePO4) batteries. The new batteries in the Delta 2 can take at least 3000 cycles before dropping to 80% of their original capacity, whereas those in the original Delta would only need ~500 for the same drop. And although I don’t have a second mains charger, I did use my bench power supply to charge it together with the mains charger at just under 1000W. Performance

Even though they’re all 2KW or less they have induction motors which can draw over 5 times that when they start up which is more than the 4800W surge the AC200P is capable of. But it handled almost every handheld machine I tried including a powerful 2000W router. I did try just one panel and although you can see its voltage on the power station, you won’t get anything from it. Two panels provided around 40V and was enough to charge the unit. Testing possibility of using car charging port with a single panel (not supported in PV mode)A: Working time (estimation) = 500Wh* 0.85 / operating power of your device. (0.85=Conversion Rate) I’m not sure what size panel to go for, living in the UK it’s not always sunny. The Victron 175w looks good, but should I go smaller as the unit doesn’t charge over 120w? I got the full 8.2A off the car outlet on the EcoFlow River Max – which at 13.5V equates to around 110W. This would charge the unit from flat in around 14-18 hours. Car charging port also accepts 24V input Alternatively, make sure your devices are at least 50% charged, as it takes up more energy to charge devices that are below this limit The display also shows how much power is coming in from the mains or solar panel, and also how much is going out to your devices. We tested the accuracy of this reading with a power meter, and it was accurate to about 1% (i.e. very good). Dimensions
