Good morning, all this is the power oak ac200p. The p stands for phosphate, so this is a lithium ion phosphate portable power station. This is a 2000 watt hour unit, which has a 2 000 watt, pure sine wave inverter with two uk style outputs. There are numerous other outputs, including 12 volts, 25 amps, 12 volts 10 amps cigar lighter a couple of 12 volt, 3 amp 5521 connectors a power delivery, usb type-c, which runs up to 60 watts and 4 usb type, a on the left hand side of the unit.

There are two inputs: this one is the solar input and this one is the input for the supply power adapter. Now you can use both of these for power adapters. If you have two adapters and the necessary cables and on the top of the unit, there are two 15 watt wireless charging pads accessories supplied are a 500 watt, 58.8 volt power supply 8 amps and a bunch of cables and more about those later, i'm charging the Ac 200p up to 100, using the supplied, ac, adapter and then we'll do a full discharge test into a heavy load and the heavy load i'm going to use is an electric car. So that's plugged into the car charger socket.

There's the car charger the little black box bottom right connected to the car, here's my setup for the full discharge test. The power bank is now at 100. I've got a power meter here to measure the total watt hours or kilowatt hours. We can look at the sine wave from the pure sine wave inverter on this graphical multimeter.

Okay, let's switch on the ac inverter and i've set the car charger to eight amps. So we should get close to the two kilowatts. Let's have a look and that's the test started and yes, the car is drawing 1.7 kilowatts. Let's turn on the graphical multimeter and we can see that the output voltage is 225 volts ac.

Let's look at some numbers here: 16 80 watts on my meter on the power oak meter. It's 1770 watts we're down to 90 percent battery uh. We've got 225 volts ac here, 50 hertz and that's the shape of the sine wave and we can get additional information on the battery pack by pressing the battery symbol in the middle here, and we can see that the battery is currently at 50.2 volts. We've got 38.3 amps being pulled from it, and it's down at 79 there's also additional information on the ac inverter available.

If we press the ac load button, we've got 230 volts going out to the car 7.7 amps 1771 watts and the frequency is 50 hertz. The battery is now down to 50 percent and we've accumulated 707 780 watt hours. Now, if you're thinking, that's only going to give 1600 watt hours when the charge is down to zero percent, we do have to take into account depth of discharge and also inverter efficiency. So depth of discharge is 90 percent.

Inverter efficiency is 88. Let's do a calculation if the total energy capacity of the power bank is 2000 watt hours multiplied by 0.9 for the 90 percent depth of discharge multiplied by 0.88 for the 88 inverter efficiency and we're looking for 1584 watt hours well, the battery is now down to 2 percent and we've beaten the predicted 1584 we're now at 1594.. Let's see what the final number is when the battery gets down to zero percent and the power bank reaches zero percent. Now 1584 was predicted, we've actually got 1703, so it's done quite well and now that the power station is at zero percent, i thought the most sensible thing to do would be to connect it to some solar panels and start charging it back up and to do This you need two cables, this one, the aviation plug to xt90 and then the xt90 to mc4s, and you want to put your solar panels in series like this.

These solar panels are power: oak 120 watt folding, solar panels, 160 watts from those two solar panels. Now the manual does recommend putting three solar panels in series, so i've brought out another solar panel here, they're all in series and we're getting 240 watts we're getting now. And if i touch on the solar panel input, we can get some more information, so that 240 watts nearly 250 55 volts, 4.5 amps, making 250 watts and we had about half an hour or so of sunshine, and i managed to put seven percent into the battery. So i'll finish off charging this with the ac adapter.

I don't have much that will draw 25 amps at 12 volts, but this thing will get close. It's a crypto currency miner, and for this i need this cable. It's an aviation plug to xt60. Now this doesn't come with the ac 200p, but you can buy it from power oak as an accessory switch on the dc subsystem dc on the ant miner has come on we'll watch it spin up and then start to mine cryptocurrency, and while i do this, i'm Going to leave the ac adapter hooked up so that we can see the ac 200p running in pass-through mode where it can be charged and discharged at the same time, and we can see that the cryptocurrency miner is drawing 204 watts.

Let's take a look at those numbers in more detail now these 12 volt outputs are high they're automotive, 12 volts. So this one is 13.4, currently 240 watts. You can see that's about 18 amps at 13.4 volts, so you do need to make sure that the equipment you connect to the 12 volt output of the ac 200p is happy with a range of voltages a little bit above 12 volts and as far as pass-through Mode is concerned: you can see that we've got 240 watts going out on the dc output and 460 watts coming in from the ac adapter, so pass-through mode is supported. That's been running now for about half an hour.

The power bank seems entirely happy to supply continuous 18 amps from that 25 amp output to test the cigar. Lighter output, i'm going to use this small electric 12 volt fan, but this is actually 12 volts, 15 amps and this fan is actually running. Okay, because the 12 volt output has actually pulled down to 11.6 volts, which is keeping the power level down to about 120 watts, the current at 10.6 amps. So it is managing to supply this fan without a problem, and now i've connected this small immersion heater.

This is a sort of one cup water heater to the cigar, lighter output and we'll wait to see when this water boils for this device. The voltage is at 13.5 volts, it's actually drawing 140 watts, seemingly without difficulty, 10.4 amps and a few minutes later. There's the water starting to boil so it looks like you can overload the cigar lighter output by a small margin without any problem on the 12 volt 3 amp output. You might connect something like this battery charger charging.

These four ladder, nickel metal hydride cells. It looks like it's pulse charging, but it's occasionally pulling 18 or 20 watts, which is 1.4 or 1.5 amps. Again, that's at 13.5 volts the usb type-c power delivery port can be used to charge something like this chromebook laptop, that's drawing about 25 watts and for a bit more detail on that 9. Volts 2.6 amps about 22 watts, but to see just how much power i can pull from that usb type-c output, i've connected to another power bank, which actually has a type c input and we're able to draw 67 watts which in more detail is 20 volts.

3 amps uh 62 watts that measuring device is saying and to test the wireless charging pads. I can move my phone onto one of them and yes that started to charge and the phone is drawing about 10 watts from one of those wireless charging pads and finally plugged into one of the usb type, a ports. I've got this wireless smartwatch charger and that's starting to charge the watch and drawing just a few watts to check the vehicle charging input. I'm going to use the final supplied cable, which is this uh, 12 volt or 24 volt uh vehicle accessory, socket cable that plugs in via xt90 to the aviation plug, which is plugged into the solar input on the power oak.

For this we need to go into settings and just change the dc input source from pv to car and then come back out and to test this. I'm going to plug the cigar lighter plug into another power bank and the ac 200p is charging at about 100 watts, which is 12 volts, 8 amps. Let's just check that in fact it's receiving 13 volts 8.2 amps 106 watts. So, to sum up, the ac 200p is a lithium ion phosphate portable power station with around 15 to 1600 usable watt hours of storage capacity.

Lithium ion phosphate is a safer battery chemistry than nickel, manganese cobalt and also has more charge and discharge cycles. Thousands of cycles, rather than hundreds for nmc, so it's a powerful machine. In fact, it's a bit of a beast cheerio.
