See the video for the Storm2 in use. Following is a transcript:

Here’s a review of the Shargeek Storm 2 power bank. I picked this up because I wanted a power bank with USB type C and raw DC power output. I’ve been really happy with it. You can see it has a clear polycarbonate case that looks great. The circuit board is nicely done, they’ve got this gray and yellow theme which comes together nicely.

Ports on the side are DC in or out, a USB type C that can be used for charging or output, and USB type A and C that are output only. They’re marked but the labels are pretty small.

Of course the main thing you notice is the OLED display. It’s small but packs in a lot of information. If you have sharp eyes you’ll love this display. If you don’t—like me—you’ll need your glasses. It’s small. You’ll see icons across the top when you plug in devices. The bottom left shows input power and output power in watts. It also shows voltage and current but I challenge anybody to read those numbers without a magnifying glass.

On the right side the display shows battery charge remaining at the top, which is totally unreadable but the color will change when it gets low. Then you have total cell voltage, cell current, and two temperatures which I believe are the circuit board and cell temps, and finally a timer showing how long power has been drawn from the batteries.

I’ll walk you through the menus. Long press to get into the menu, short press to move between items. First is the DC power output—I’ll come back to that. Next is the cell voltages and cycle count. Next you can change the temperature display. You can reset the timer on the main display. More display settings. You can force it to power off here. Or exit the menu.

I skipped past the DC output which goes to the barrel jack. Let’s look at that now. You need to turn on the DC output in the menu. When I do that it brings up a warning which says to not try charging from the DC jack when the output is on. Long press to continue.

The first two menu items increase and decrease in whole volts. The two below increase and decrease in tenths of a volt.

It’s hard to see from the tiny display, but the DC output makes this power bank really useful for powering electronics projects. That’s part of why I selected this one. If you don’t need the DC output, you might want to look at their smaller model which just has USB output.

I’ll show you here the Storm 2 powering a Pinecil soldering iron using the USB type C output. The iron has no problem drawing the current it needs from the power bank. This has proved wonderfully useful for my various projects.

Finally, here’s a DC load on the barrel jack. I have the voltage set to 20 volts out, and my little load box here will draw 1.5 amps, or 30 watts total. The power bank does that no problem. One thing I discovered, however, is that the barrel jack is 5.5 by 2.5 millimeters and most of my barrel plugs are for a 2.1 millimeter center pin, not 2.5. This is pretty annoying. For this test I have a 2.5 to 2.1 adapter on the power bank.

Overall I’m really happy with the Storm 2. It’s wonderful for the kind of projects I have around the house, and it lets me work wherever I want without having to find an electrical outlet. Please don’t tell my wife I’m soldering at the kitchen table again.

Downsides are it’s a little big and heavy for travel. I might pick up their smaller model for that. And I do wish the display was a little bigger, as it can be hard to read. Still, five stars, I’m glad I bought this.

Speechless. It's beautiful. I'm an electronics engineer so anything in a see through shell gets me all sorts of happy. The build quality is impressive and I can see a well thought out design. The screen is bright and colorful but the settings screen text is so tiny they should put a curved magnifier on the display not only to enhance viewing but to protect the screen from damage. There is also a warning about not applying power at the same time it is in use. I can't determine the nature of this warning but I can see someone accidentally charging while it's also in use so protection should be implemented. With care, this is a great device. The yellow cable is flexible and feels like natural rubber. You get a nice protective pouch and a well written instruction booklet.

Updated Review - Don't buy unless you have or are prepared to buy a minimum 100W rapid charger.

2nd UPDATE 2/23/23: I have once again downgraded to 1 star. I was able to make use of this Power Pack for 3 months. Then I mistakenly left it connected to charge my laptop overnight using the 12v output. While my laptop did successfully charge to 100%, the Shargeek Stom 2 did not survive! By the next morning, it was completely discharged to a point it won't recover. No mater the charger (65w, 100w and 130w) or any Shargeek recommended button press trickery while plugging in the device, it won't power up. It is now a cool looking $200 paperweight.
UPDATED 11/1/2022: After a some painstaking trials, I was able to get my unit charging again. As a result I've changed my review from 1 to 3 stars. I still can't give it 4 or 5 since A) The device should have never been allowed the LiPo batteries to discharge almost to the point of no return. B) This battery pack requires maintenance (regular charging and discharging cycles) to prevent the over depletion. The owner's manual actually recommends charging the unit and discharging 20% at least once every 3 months. C) You shouldn't have to drop an addition $50+ dollars for a charger just to be able to use this.
It turns out this thing needed a min 100W Type C charger to heal itself from the excessive battery drain. If you don't have a +100W charger, you should be prepared to get one as a 65W rapid charger couldn't cut it. Even with my new charger, it took two attempts at leaving it plugged in for an extended time to get it to start charging normally. Now that it not completely dead and appears to be working normally again, I'll be testing it to see if a more common <100w rapid charger will work.
Original Post---- Worst $170 I've ever spent! This thing looks cool but for as sophisticated as this thing is, apparently it doesn't have battery shut off protection. I bought it for the adjustable DC out (and because it looked cool!) but I never actually got to use mine so I can't say if this thing actually does what it's says. Unfortunately I'm out of my return window. I turned it on when I first got it just to check it out. I turned it off but apparently it isn't truly off, just asleep and still burning battery power. When I actually needed it about a month later, I was shocked it was completely dead. So dead in fact it can't be charged! This is a problem with LiPo batteries which is why all good electronic devices will turn off before the battery is completely discharged but not this one (Even Harbor Freight Tools do this). Now when it is plugged in, it turns on but displays ”Low Energy, Long Press to quit". If you try and quit it will just reboot and display the message again. Save a $100 and just buy an Anker battery pack. My Anker is always ready to go with a full charge even after sitting for months at a time.

The perfect charger for geeks and gadget lovers

Reviewed in the United States on December 27, 2023

I am using this charger to keep my macbook pro charged during trips. It is a bit heavy, but has all the features and capabilities I need, and it is small enough to pack away conveniently. When I connect my mac charger to the usb C input, this device charges taking full advantage of the 60W charger pulling 3 amps at 19.4 volts (first picture). When I use this to charge my mac, it responds to the requested charging voltage and current, as shown in the second picture. That is often slower than I would like, but works adequately. It is a feature of macs that they use slow charging to preserve the computer's battery.

My only complaint is that the screen is so small, you need incredible eye sight to read the smaller numbers. If you have average eye sight, you will need a magnifier. If you have poor eye sight, dont buy this.

If you have decent eye sight and are a geek or love gadgets, this is an excellent charger. It reports every wattage, voltage, current and temperature available and is an engineering work of art. That said, the interface has many strange behaviors that will not be apparent to the average user. If you long press the main (yellow) button, you will move to the second level graphics user interface where you will have access to seven additional screens which control the DC output, battery pack properties, temperature units, system reset timing, display setting, power, and return to the main interface. Some of these screens have weird behaviors that are counter intuitive and annoying. But a true geek will find work arounds that will keep you in the game. And for most users, these additional screens can be totally ignored.

First of all - this thing is great to look at. Plenty of info on the display screen (if your eyesight isn't fading). and the display functionality is a bit frustrating, but does a great job when interfacing with a single button. I took this through Europe and Asia and had no troubles in the airports. It kept all of my gadgets charged and was quick to recharge. I'll buy another when I need to.

I absolutely love this battery, it's been working perfectly for me and helped out during an extended power outage that we had the other night as well. I'm very technically advanced so I like that it has the display which shows all of the voltages and other information on it while it's in use, it's very convenient. It also looks really slick with the see-through case. I would highly recommend this to anyone who is looking for one of these battery packs.

Screen died, I returned it. Then I didn’t.

UPDATE:
It's been a few months. I just had to remove the endcap again, to hit the reset button because the display and secondary port were not functioning. This is the second time. I think it happens when it dies completely. It's only happened twice. Once while initially testing, and again after having let it completely die. Which is rare. The display seems to die AFTER connecting it to charge from 0%. It still charged under these conditions, and the main usb-c port functions. The second one won't until you reset. Which requires tools to remove the endcap and expose the reset button.

I also just upped my review by two stars to 4. I'm keeping a star since they solicited my review originally and I loath marketing and snail mail.

Truth is, I use this thing. It works well. Charging at 100w is no joke, and the heat sink functions well in this device. Overall, it's the best battery bank I own. It's my goto around the house, or to test cables, And I'd travel with it. I've grown to appreciate very much. No clue if the company is any good, and right now I'd not put any faith in them at all. But the battery bank is quite good IMO.

-------------

It was expensive. The percentage is really hard to read. I like the outputs and charging speed. I don’t like the single button long presses. Or the wasted screen real estate. My screen stopped working today. It’s still charging because my charger shows 90w flowing in. I don’t trust the design. This feels like a software bug, and I’d rather have something that works. I’ve completely depleted it around 3 times in 20 days. Each time I was a little paranoid it was just going to die, based on other peoples reviews. I’m glad mine died while still within the return window.
I was also solicited to film a review for a $50 refund.

Meh, other reviews say the company isn’t responsive for support. Perhaps marketing should run support, because they snail mailed me unsolicited with their refund offer. I don’t appreciate that. If your product is good, it should speak for itself. If it can cost $50 less, then why did I pay 199?

The screen was working but after being connected to an iPad, at some point it turned off and never turned back on. Hitting the button does nothing. Long pressing for 10 or 30 seconds does nothing. I hooked it up to a charger…. It is charging fine according to my charger. It charges fine also.

Other cons, Powering off the device takes 7 presses of the button, including two long presses. It’s just kind of a mess. I wish there was a physical off switch because from the looks of it this thing needs to be reset or some thing. But I wasn’t looking for a Hobby. I was just looking for a decent battery charger with decent stats. In hindsight this thing was incredibly expensive for what it is. Meanwhile my other USB-c battery bank has been in my truck for seven months and is at 99% still :). It’s not as fast, it’s not as large, but I don’t question that it’s going to function.

I decided to open it up. The screws are crazy fine, and there is no lock tight. I held down the reset button and yeah it cleared the bug.

I went looking for other battery banks of the same or smaller size, and with two USB-C ports… Honestly the best thing I found was still $150 and didn’t specify the type of cells it was using.

At the end of the day I couldn’t find an equivalent battery bank. At least with this one I can view the build quality of the board, I know that heat is decently transferred to the end caps, and if it gets wonky again I guess I’ll just open it up and try to fix it.

So yeah it’s Jenkee, but the other battery bank I viewed only charged at 45 watts, it was rated to charge 100 W. This one legit charges at 90 watts. To me that’s the most important thing. When I forget to charge it I don’t wanna be waiting around more than I have to.

I don’t know maybe I’ll upload a video and get 50 bucks off since they solicited me to do so. But I sure didn’t like that they sent it to me.

Will this thing last? I’m feeling like it won’t lol but I think I’m just gonna keep it anyway. I have no idea why they didn’t drill hole so you can hit the reset button with a paper clip. Seems like common practice to me.… Maybe I’ll drill that hole seeing how I doubt I’ll ever get warranty support with this company.

Really cool

Really cool power bank. At first it’s a bit of a chore to set it to the output you want, which in my case it’s (dc). but once you get used to it, it isn’t so bad. Here is an example: You have to hold the button to turn on- hold again to get into settings-hold the button again to select dc - hold the voltage + option to get the voltage you want - then you have to press and release the button multiple times to get to the (on) option - hold the button to turn dc on - press and release the button until you get to the exit option (x) - then it takes you into the main screen. If you want to access the display timeout option you have to hold the button again to get into settings, and press and release to get to the display setting. Basically the workflow is by press and release to get to a setting, and hold to actually select and initiate the setting. One problem I have with this device is that you have to manually turn the dc option off . There’s no auto shutdown and if you turn the battery off while in dc mode, it turns back in by itself. I tried to ask if there will be any firmware updates but I could not get a clear answer. I can still live with turning dc on and off everytime though because 1. Battery charges super fast by usb c (even at 65w) compared to most batteries. 2. The battery lasts a really long time. 3. The battery displays cool information on the display (although you have to manually get back to the screen). Battery still worth it though
