27000mAh Portable Power Bank with 100W GaN Charger 100W AC Outlet 140W PD USB-C Fast Charging 160W Total

I have to say when I saw this slide into my recommendations from Amazon I ordered this without really any hesitation. There are a couple reasons, first I have several power stations ranging from 25 kWh down to 27k mAh ones for travel. I've never owned or even seen a unit that combined both in a compact package. I also have a number of ZoupW solar panels and they are some of my best performing ones. I've even had to reach out to them on a warrantee issue for one and they took care of it within 2 or 3 days. So when I saw this, like I said I ordered no hesitation. I'd lie if I didn't say I've been eagerly waiting on this to arrive. Well when I got an early Xmas present and Amazon delivered it a day early I was thrilled. I ripped into that like a 10 year old Xmas morning and plugged it in to charge up, then read the manual. This is where I was first surprised and kind of relieved. You see there was, to my surprise, no required app to install. It's a “dumb” device that works without all the unnecessary overhead. I started by plugging this sucker into another power station capable of 140w charging to see how much it would take. While the ZoupW showed 85-87w my charging unit was showing 96. My unit started right around 50% and didn't take terribly long to reach 100% on the display. I noticed though the other power station was showing ~20w load still. I let it sit like that for another 30 min or so and saw it dropped to a 7w load and eventually to 0w after nearly an hour. So if you really want this unit topped off be sure to leave it plugged in a bit longer. Now for the fun stuff, I found a HEPA filter in my house with 4 speeds and power draws (30, 50, 80 & 100 respectively). After turning on the AC mode I checked the voltage and was quite surprised to see it was only 111-112v but the sine wave was nice and uniform. No square wave tops like I've seen on some other mini units. At first I was concerned about the low voltage but everything I tried worked fine. The HEPA unit operated normally except it ran about 10% slower and in watts peaking at 92w. Other devices and chargers all worked fine as they appeared to be designed for 100-240v input. This unit is very similar in size to my other brick style airplane approved power stations. In my image I've got it next to EcoFlows flagship unit. This is just a bit larger but offers nearly the exact same capacity and has the optional 110 output. The ZoupW feels really solid and well built and I really like the see-thru design. For the price I'm not sure if I was in the market if I'd have chosen the EcoFlow. I do love the retractable cord on that but it's not without its quirks. None of which I've noticed on this unit. Aside from the charging to 100% item mentioned the only thing I was disappointed to learn in my testing (not that ZoupW ever claimed it would do mind you) is that when powering an AC load if you plug in a USBC charger it immediately kills power to the AC ports and you can't turn them back on until you stop charging. It would have been nice if it could do both simultaneously. Then this unit could have been used as a small portable UPS. I mention it in case someone is considering buying this for such a purpose.

This Power Bank is large and powerful, it has two USB-C and two USB-A ports. It also has a 110v AC outlet and a bright flashlight built in. The Power Bank is about 7 inches long and weighs just under two pounds at 1.82 pounds. The instructions state that it is "Flight Approved", but to check with your Airlines, as it has Lithium-ion batteries. Charging this battery bank with a 5w phone charger was going to take a long time. The instructions state that this battery can be charged with a 100w GaN Charger (sold here on Amazon) in one hour. The battery bank arrived at a 50% charge. I used a wall charger that is rated at 50w, the power bank showed it was getting 44w, to charge the power bank to 80% in about 20 minutes. (It is hard on Lithium batteries to charge them to 100%, it will short the life of the battery). The instructions are in very small print, and there is one part that is important so I will copy it here: "USB C1 is a bidirectional PD interface with an insertion detection function. When a device is inserted, it will automatically turn on. Press the DC button for a short time and then for 2 seconds to turn on the output mode. When the device is removed, the PD icon goes out and the function is automatically turned off. K1S automatically enters sleep mode after 20 minutes of screen off. During sleep mode, charging some products through the USB-C interface requires short pressing the DC button on the device to wake up K1S and charge the device". The USB-C2 port does not require these special actions, just push the DC button to wake the power bank up. The USB-C1 port is bidirectional, used for charging the power bank, so it requires these instructions. I used the AC 110v outlet to power a lamp, which drew 5w, and it worked just fine. I wanted to see what the AC outlet would power, so I tried a hair dryer. On the low setting of the hair dryer it drew 58w. Once I attempt to change the setting on the hair dryer to medium, the Power Bank shut off and showed a red circle in the display. (the low setting on the hair dryer is not useful). The outer case of this Power Bank is plastic and feels very solid. Read more
