You do such a good job at answering all of the questions consumers want the answers for but would never get from the manufacturer. Please do reviews like this on other things if you can, I know everyone really appreciates it.
Great review. I have a portable gas generator, but worry about the dirty sin wave for my electronics. Got one of these to fill that role in a power outage. I may also use it for some tailgating.
Good info, thanks. The CLA info was very handy and good to know. I see a few good use cases for me... yeah, not the best, but for the price point, I don't think you can beat it. I guess I'll find out.
I played this video from my phone, on my pillow, next to my head... It was like counting sheep 🐑 🐑🐑😴 💤 Imagine someone reading a user manual 😮😅 Passed out quickly
For the efficiency comparison part, there is no way to have such an inefficient pure sign wave inverter in reality. The internal battery pack of ps70 is 4s20p, which means it will be fully charged at 16.8v. However, the internal charge circuit will cut off at 16.1v meaning the battery is only charged up to 90%. When I bypassed the internal charge circuit, I was able to charge the battery all the way up to 16.6v(that's where the BMS cuts off) using an external charger. After that, I tested the ps70 @ 70w constant load and was able to draw 615wh. I believe they did this as a safety feature to prevent overcharging but went too conservative with the termination voltage.
Great review... I grabbed one of these as just a backup to my two eb70... Will probably end up gifting it, as two eb70 and two ac500 will more than satisfy my power needs... The 12 volt output on the b300s has run my iceco vl65d for five days without charging, and is still showing three dots, or 50%...incredible! With performance like that on just the DC side of the b300s, I may not even need the two eb70... Now, to the meat...we've now seen your mounted swords twice... where's the lightsaber collection?
I practiced sword martial arts many years ago. I don't have any collection of swords other then the ones I used. One is a non-sharp aluminum blade Iaito, the other is a steel Shinken. That said, I'd go get a lightsaber if they made real ones.
Nice review! I need a replacement power adapter; mine went astray during a move. Could you give me the product number for it, please? Should be on one of the flat sides. Bluetti wasn't able to help. Many thanks in advance.
This was a great video. I need some help please on the math to calculate how long it will last running LED strip lights. I'm trying to run 70 feet of LED strip lights. I'm powering them with 1 9A PS, 1 8A PS, 1 6A PS and 1 5A PS. Thanks in advance for your help.
Excellent review! Is barrel connector unregulated? 16:05 it started with different voltage. If this is the case efficiency should be measured separately?
Very informative - Thank you! I'm wondering if this unit would power a small guitar amp and a few usb powered effects for busking. I ordered 5 with my ac500 order because they were so cheap.
Great review! Thanks.. I have 2 GZ yeti 1000's with the 8mm charge plug. Is there a recomended adapter I can get to use the chargers and panels I have for the GZ? Thanks!
On the AC voltage test - there was a drop up front from inrush. I haven’t seen my other units do this but curious as to the fidelity of your equipment if you have.
I have seen similar temporary voltage drops on other Bluetti devices. The load being used was an array of incandescent light bulbs. They are cheaper than big resistors and don't have much (if any) inductive load properties.
You can charge one PS70 off the output of another one. I would expect between 20-30% losses in the discharge/recharge cycle. It would be more efficient to switch your loads from one unit to another when the battery is depleted.
I’m enjoying your videos. I just got the EB3A and while I’m liking it it doesn’t charge my iPhone 12 max very good on the wireless top part when it’s not plugged into an AC power supply. The phone gets hot. The top of the device gets hot and I don’t know if I have a bad unit or if that’s typical. 🤷♂️ Also it regularly puts out an unusual smell while only having my CPAP and one light on while on AC power. I’m wondering if I should return this one or if this is all normal for this little guy? IDK? 🤷♂️
One more comment, your classification of THD isn’t quite correct, it’s not the percentage that’s not a 60hz signal. It’s the amount of harmonics on the line compared to the fundamental.
It is a bit easier to explain it that way. I didn't what that to go very math-heavy in the description and still have the results of the test be approachable for folks that have never heard of "frequency domain". That statement assumes the fundamental frequency in use is 60hz. Comparing the harmonics to the fundamental is effectively giving you a percentage.
It takes at least 22 volts to get to the max charging rate of 209 watts as displayed on the screen. At 22 volts you are looking at 9.8 amps. It will hold the 209 watt charging rate all the way up to 46 volts at 4.4amps. The advertised max voltage input is 45 volts, so I wouldn't recommend exceeding that.
I find it kind of funny that nowhere on their website dose it state how many cycles do you actually get from this power station. Why would they not put that unless there trying to hide something
True. They don't talk about it on the PS70. It is using the older Lithium-ion battery technology so I would expect more like ~500 cycles to 80% instead of the ~3500 cycles you get on the more modern LiFePO4 chemistry. That said, it was $99 for this.

Well done detailed review. Being able to choose the most efficient solar panel based on the charging input information is great.
Excellent info, bro. I just published a video, I mentioned this review and linked this video in the description. You the man.
Another great review for the average Joe out here (myself). Easy to follow. Thank you.

Great concise review, well done!... I ordered 2 AC500s, so I grabbed a few PS70s as well for family gifts etc.
Awesome job Jeff! Keep em' comin'!!
Awesome!! Great job and very well explain.

Great video- I was curious whether this could handle input from a panel that fluctuates between 40 and 46 V. Now I know.
Thanks for that nice video Jeff 👍 hope you will make one with the EB70 😊
Interestingly enough, I have an EB70S on my workbench.
Great review...

Does it allow pass-through charging, as the EB70 does, since the charger is the key difference between the two?
Excellent review!
Is barrel connector unregulated? 16:05 it started with different voltage. If this is the case efficiency should be measured separately?
It isn't all that well regulated. I didn't disassemble it to determine if there is a regulation circuit behind the output.
Very informative - Thank you! I'm wondering if this unit would power a small guitar amp and a few usb powered effects for busking. I ordered 5 with my ac500 order because they were so cheap.
It would power it, but it might make a hum. The total harmonic distortion numbers on this inverter are not as good as some of the other ones.
Great review! Thanks.. I have 2 GZ yeti 1000's with the 8mm charge plug. Is there a recomended adapter I can get to use the chargers and panels I have for the GZ? Thanks!
An 8mm female to MC4 converter would do it. The PS70 comes with an MC4 to DC6530 (6.5mm x 3.0mm) adapter.
On the AC voltage test - there was a drop up front from inrush. I haven’t seen my other units do this but curious as to the fidelity of your equipment if you have.
I have seen similar temporary voltage drops on other Bluetti devices. The load being used was an array of incandescent light bulbs. They are cheaper than big resistors and don't have much (if any) inductive load properties.
What type of connector is the charging input? Looking for an adapter for my solar blanket that uses a DC5525 barrel plug. Thank you!
Most panels either use MC4 connectors or have a way to convert to them. I would go that route. The PS70 has a MC4 to DC6530 cable in the box.
Thank you for the review! I snagged a few of these as well to gift to others. Is it possible to hook these up into series?

Devices being inductively charged will get warm. It is normal for that.
The smell will go away after few recharge.
@@DLong-wp8su Thanks. I believe it is improving and I probably wouldn’t be able to notice it so badly.

Just received ours! Is the maximum solar charging 209w and 24v?
It takes at least 22 volts to get to the max charging rate of 209 watts as displayed on the screen. At 22 volts you are looking at 9.8 amps. It will hold the 209 watt charging rate all the way up to 46 volts at 4.4amps.

on alibaba they claimed >1000 cycles. in this device battery cells works in voltage range from 3.3v to 4.0v to increase cycles count
Is the Bluetti app work with this power station?
No. The PS70 does not have app support.
PS70 for $100? Where?
It was part of the AC500 indiegogo campaign
@@WaveformScience So you had to buy the AC500 to get it for $99. I just picked one up for $199 a day or two before black Friday.
This Bluetti PS70 look like SUAOKI S670.
They were both made by Poweroak. Poweroak is Bluetti's parent company and owns the factory.
ps70 for $100?
