Ugreen PowerRoam 1200 battery power station test and review 

I respect the courage and confidence in their product it took to send things to Matthias.

Using the saw as a resistor was a brilliant demonstration.

Love how thorough your are at finding any possible way imaginable to torment these devices! Gives me a good chuckle while also learning. Cheers!

What is the circuit diagram symbol for "circular saw resistor"?

Nice using your circular saw as a resistor! That gave me a chuckle. I had similar results testing the storage capacity of power stations. Like you, I was measuring AC current out, but of course inverters aren't the most efficient things. The company said if I were to discharge it with DC, I would find it would reach the rated storage capacity. Probably true, though I never tried it.

The thing I like most about these reviews is you're not saying this power station *should* run power tools, you're using them as a point of reference that's familiar to you audience while providing real data about the sort of output it's capable of. It feels like so many people would be inclined to review these things by plugging in progressively more demanding things until they hit a failure point and just say "hey so that's a pretty high failure point so I guess this thing's good." Really appreciate that you provide so much more depth.

I absolutely love how you are doing these "sponsored" reviews - please continue to do them if you are able to :)

I laughed out loud when you connected the circular saw in series. I can just imagine you submitting a bug report about it. So funny

Goodness me.. I bought a few things after watching your videos. That thermal imaging camera was so amazing. appreciate the reviews. Highly enjoyable and technically rich.

Pretty nice device, Matthias! Great review! 😃 Stay safe there with your family! 🖖😊

Thanks for the comprehensive review. That unit looks pretty much like clone (or "unbrand") of an EcoFlow River. I'm glad the market is getting the price point lower so more folks can benefit from have emergency power (or in my case, power when I'm boondocking in my little trailer).

I love this one!! adding it to my wishlist....

He tests things better than anyone I have ever seen, way better. From Research In Motion, to Research in Overload protection.

Was half expecting you to drop test it

This was a very timely vid Matthias, was looking for something to run a freezer if power was lost during these forest fire months. Don't need a big unit, just 1000w -1500w.

I didn't understand everything you talked about but I watched it all to support your efforts!

Ugreen is already charging some phones here... *BUT* a _Matthiasification_ like this one makes me sure there's this power station in my future. I'd want a *"WANDEL"* tested on my tools (most). ❤

You should do some testing with a soft start motor starter. They work wonders on RVs to start motors on solar or generator power.

I usually think of ugreen for those people who make fairly okay bluetooth recievers/transmitters, great to know they have the bravery to send a battery power station to you

Looks like a quality item... looks great for camping.

4:15 is one of those moments your left neo-cortex has to overpower the limbic system kicking in and risking arrhythmia… …”Hey chill bro, if he was hospitalised, this upload wouldn’t exist to potentially hospitalise you!”

One point, while LiFePo4 is technically newer than the 'classic' lithium ion - but it's not a particularly new technology. Invented in the 90s and was commercially available within the 2000s. It just seems like it's starting to really hit in consumer products in ways we just haven't seen in the past. These battery banks are perfect use case where volume is a little bit secondary to safety, cost and longevity.

Watching you slam a saw right into the power cables was exciting

Nice. The battery capacity and output wattage are just enough to be useful ; my EB70s is great but the output wattage isn't enough to run most heaters.

Thanks for the review. On a safety note: All I can say is you are lucky your saw stopped working... please be more careful, you almost cut thru an electrical cord! (4:15). You should never be coming close to a cord with a saw like that.

On the spot 👏

That was a great information dense showcase and review. Love that huge list of tested devices. One general question when it comes to portable power stations; Would the amount of distortion on that sinus mess with sensitive devices? Ie. If I have a PC connected and then add an inductive load like a medium sized drill. Would the PC flip out or even be damaged, or is distortion like that something that could be handled by the PC's internal PSU or a laptop's external power brick?

Extensive review thank you. Does this unit function as a UPS if so what is the switch over time for the unit?

Love the "My fans" part lol

I've been on the fence about these guys. Anker was who I trusted but after recent events and then having bought a few of their dual port USB wall plugs that severely underperform their specs, I'm kind of done with them. I bought a couple dual port 5V 2.4A chargers and it states that it's 2.4A per port. I can't get but 2A from one port and if I plug in something in the other port it drops to 1.7A. The LED lights I'm trying to power pull 2.1A and flicker when underpowered. These types of videos are surprisingly useful for figuring out the integrity of companies you may not know. I'm going to give them a shot now.

Love all your power station videos. i saw in the comments you mentioned they are good UPS's. Doing my own research I've found they are not recommended to be used as such. Would love to see you test that. Also, a lot of people get these things for backup power for medical devices like CPAPs. In my research, a lot of these shut off if too little power is used and sometimes that will shut CPAP's off in the middle of night! edit: I just double checked and ecoflow delta says it takes 30ms to switch to battery power. A quick google search shows that to be a little high for a UPS. I wonder if it's still safe for electronics.

Stopped that saw right in time of you cutting the cord @ 4:22 ? I wonder why virtually none installs soft start circuits in powertools. No only it does not try to rip your arm off the socket but also prevents such surges. 🤷‍♂

I appreciate your reviews. I've been wondering about getting a solar power station (Jackery or some such) to use for recharging tool batteries (18 and 12 v.). I'm clueless for what exactly I'm looking for. Any thoughts or advice you might have would be greatly appreciated.

About 15 years ago, I had a very small APS UPS (220W max?) and accidently plugged a 1000W space heater into a power strip which I momentarily forgot was plugged into the UPS. Bricked it. I was surprised that there wasn't even a fuse/protection or something inexpensive to replace. And APS said they don't repair this. 🤔☹😡

Great video! 😎😎😎Interested in reviewing our 2100W portable power station - Energizer PPS2000?

I'm curious if the device could power a load while charging, like if I had some computer equipment that would stay powered up 24/7 while the device charged up via solar only during the daytime. The other one is if it can be set to turn on after discharge shutdown, like if it is in a remote location and has a string of cloudy days, will the output power back up once the sun is out? That being said, thanks for the review and showing the power tools it can and can't power!

Discharge load changes the capacity of cells. You gotta look at the cells datasheet and see what draw they got the numbers from. Most 18650's are rated at 0.1C(at least the ones I own and have tested). I suspect they took the stats off the battery pack and not though their box.

Hey Mattias great video. what was the wattage on the belt sander?

They should have an induction motor setting that allows the motors to start slower with VFD or lower voltage.

I wonder if you could start the circular saw by pulsing the trigger a few times.

I hope you’re conducting these high power consumption experiments at night. Your Canadian utility is going to ream you in your rates for charging that thing so many times! 😂

“This other brand” 😆 love the limitations sponsors put on people!

I know one man who can make comfortable single wooden handle to it 😉👍

Matthias, can you review solar panels and power energy storage solutions?

Can you make a video about why a sine wave is preferable to any other wave form?

Nice power station. Could you try some practical "real-world" tests. How about how well these units run a refrigerator and a basement sump-pump, ?

How did you get the large numbers in the top corner of the shell? Very fancy

Just for fun, try a soft starter with the tools. Waveform is expected to be terrible, though.

Wait, how are you printing out the current state using that big font to the top right of the terminal window? I assume that's some program which uses unicode U+25A0 "black char" or something like that? It's interesting that the rest of the console is scrolling normally, yet this is stationary and I would bet it doesn't ruin command history.

They could probably some kind of a "sofstart" feature, by slowly ramping the voltage, for example.

Nice test. Does it work as UPS with bypass mode?

did it save you from saw go bang! with the cable

I don't know enough about the electronics behind it; would the soft-start feature on some saws, sanders, etc. reduce the startup current so a lower-wattage source like this would be able to successfully spin it up?

Bonus speed shop tour 😂

I really want a portable power station that can run power tools well. Sometimes you just want to run a plug-in miter saw or table saw away from a plug. If I was charging battery tools there's chargers that can charge tool batteries on 12 V car batteries so I can skip the inverter part.

Do you know the max input voltage from solar. Useful to know to see if it can be overpanelled

Will it charge bigger power tools batteries? that would solve that problem at least if it will charge them a few times enough to make it worth while.

When you added the inductive load (circular saw) the inverter started to oscillate. These oscillations are concerning as they could damage sensitive electronics that might also be connected. In all fairness, one should not be connecting an 1800VA inductive load to a 1200 W inverter, and it’s no surprise that it didn’t start. I would like to see if it oscillates with an inductive load within spec (1200VA or around 1000 watts).

Matrhias, can you make a video on your big dust collector? I have always wanted to see what makes that one tick.

👍👍

It would be nice to have a high dc output for universal motors.

I like how just an hour after the video is public, Amazon US is sold out, and Amazon Canada does not even carry them. seems like Ugreen should have put some more work into making these available when they advertise them.

Can any of these handle the compressor on full sized fridge (or chest freezer)? I have an electric car with an 800watt inverter that could run lights etc for many days. I’ve been contemplating getting one of these to serve as a buffer battery so I could potentially keep my fridge/freezer cold during a prolonged power outage but have doubted they could handle the startup current of my fridges 8amp induction motor.

"And now I will wire in my circular saw as a one ohm resistor..." Hmmm... Awesome idea.

I saw a video online about using an NTC resistor in series with a motor load as a poor man's inrush-current limiter of sorts. Would this help with your power tool on battery problem, maybe?

How do gasoline generators with inverter outputs react to difficult loads like power tools?

Would it start your circular saw if you’d start it intermittently (e.g. on-off, on-off, on)

Reply: I recently watched that video too, and it's amazing how electricity plays such a crucial role in our daily lives, especially in outdoor activities like camping. Speaking of which, have you heard of the Segway Portable PowerStation Cube Series? It's a versatile powerhouse that offers massive capacity and fast recharging, making it perfect for outdoor enthusiasts like us. I highly recommend checking it out for your outdoor gear and home backup power needs!

I wonder what the performance would be in below freezing temperatures.

5:06 "this grinder thingy"

Didn't jump on it, I'm not buying 🤣💕👍

This device probably has a lower power rating per outlet and the onboard computer reduced the voltage to give almost 1300 watts. Perhaps utilizing all the outlets with the space heaters would have given better results instead of overloading a single outlet with a probable 13 amp maximum rating with approximately 18 amps of space heaters. Hence the voltage drop protection to 90 volts.

I can't find anywhere, what voltage range does it accept for solar charging?

Is there a tap from the power station battery to charge cordless tool battery packs?

Would it run your refrigerator? Thank you

Having a dedicated button to turn on IOT is a point in their favor!

I bought a similar power station sitting around collecting dust..guess im waiting for the apocalypse

Currently unavailable. We don't know when or if this item will be back in stock.

not available anywhere in Canada (online)?

I haven’t heard of this channel. I just clicked on it because I saw it as an ad. Question for you guys, what is the channel about?

Doesn't look like any 230V version availabe?

When the discount is $200, you know the price is going to make you wince.

Could this sort of device be used to charge a car battery, or even jump start it?

Excellent video. Please disclose if you were paid for the video, get the unit free, get revenue from affiliate links / coupons or any other financial relationship.

You should have to connect the router and see how quickly it turns off, when little energy is consumed.

If the saw would'nt had been stopped by the overload it would had been stopped by cutting his own powercable in the next second. 4:18 😄

Hi. Does this station have by pass mode?

not available in Canada :/

If a company dares to send their product to Matthias then their product is above average at least.

You might want to get a large auto-transformer and connect it to that power source (in series with a lightbulb that you bypass once the iron core has saturated (this can be easily automated with a delay relay)) and then connect big tools and bring up voltage slowly using auto-transformer. With big asynchronous (bandsaws) motors you could use a cheap VFD and increase the frequency slowly. EDIT: could the VFD at the output of that thing be hacked to rise the frequency slowly?

I wish you had measured how much power this device consumes on top of what is being delivered to its output (when at 100%, not charging). If I use one of these products as a UPS, the battery will always be at 100%, but I don't want it to take 500W from the wall when only using 450W at its output!

It's a good thing the saw died, you were pretty dang close to that mains voltage wire lol...

Honey, the power's out, better run my miter saw! I jest.

Oddest Shop Tour I've seen in a while.

I'm wondering,.. do you ever have a problem with laying something down and can't find it?

It’s 1000$!!!

It can power my router … Wi-Fi router :P

Lifepo4 is fairly old

I can feel this video was sped up slightly.

I wonder if you could get one of your bigger inductive loads running (let’s say the circular saw) by having a smaller inductive load already running (let’s say an angle grinder). Idea being that you first turn on the angle grinder, let it get up to speed, then when you connect the circular saw, the angle grinder will donate some of its kinetic energy to get the circular saw going. Probably a long shot, because the donated energy would have to be enough to offset the extra base power the angle grinder is drawing. And I don’t know how the inverter would react to whatever the frequency would do. But I’d be curious to give it a try.
