TECKNET Portable Power Station,155Wh Portable Charger Power Bank, 110V/150W Power Bank with AC Outlet Pure Sine Wave, PD 45W, USB QC 3.0 Battery Backup Power Supply for Home Outdoor

UPDATE: Product replaced and appears to be working with the proper equipment. Will update if any issues arise!The overall device is great! Sadly, the AC adapter on mine did not function when I attempted to use it. Thinking perhaps the voltage needed was higher than the device allowed, I attempted a simple phone plug, but the AC power not only did not work, but the AC indicator was no longer even functioning. Currently, attempting a swap of the product to see if the next one fares any better, and will update this review if it works out.

This compact power station works well so far. I'm impressed with the 150 watt power inverter. I hooked up a couple of things that pulled 148/149 watts as measured with a Kill-A Watt meter. I was able to run them for six minutes straight with no problem. It held a steady 60Hz so it does appear to be a pure sine wave inverter. Very impressive performance from a $85 power station. All USB ports worked with no problems. The built in light is very bright.Only a couple of complaints. The supplied USB C charging cable didn't work at first. I noticed that one end was shorter and began to work when I pushed harder and it went in a bit further. I may trim the plastic back a tiny bit and see if that helps. If not I'll throw it away. The other drawback is the supplied charger is only rated at 18 watts when the power station will except 45 watts. I have a 45 watt charger for my Chromebook that I can use to charge it at the fastest rate so not a big deal to me.Overall a good power station that performs well at a lower price point that the competition.

I've been using this product for six months now and am very happy with it. I've been using it to power my Roland Cube EX for busking in Santa Cruz. On my amp's 10 watt setting I can easily power the unit for 10 hrs but I usually only go for 4 before recharging. Four hours of playing at 10 watts still leaves me 80% battery capacity and I can charge it back to 100% in 2 hrs. It's very lightweight, portable, and doesn't add much weight to my gig bag. I highly recommend this unit.

Lots of stored power. At 155 watts it is just under the maxium allowed for carry on luggage. Uninstalled lithium batteries are prhobited in checked luggage. Appears well made, functions as it should and weighs in at 3.75 pounds with an esthetically old school leather handle that is strong enough. We have frequent power outages here in New Mexico and this Tecknet Portable Power Station has an AC plug for charging my laptop. It's not going to run my refrigerator but does easily charge up my laptop and phones. Your mileage may vary. I passed on the smaller units without an AC plug that often come with car battery jumper connections. I have auto club with my vehicle insurance but they won't come and charge up my phones or laptop during a power outage. This unit exceeds my expectations.

As an update to my previous 5 star review which is now 1 star: This battery worked very well, as noted in my initial review below, for 12 months. The last time I tired to use it, after charging it for 24 hours with the digital power indicator at 100, it doesn't work. At all. The flashlight won't turn on. It won't charge via USB. The power button for the AC output won't turn on and the AC output no longer works. It's barely a year old and I'm so disappointed!My laptop battery only stays charged for about an hour these days when it's not plugged in, but I had to use my laptop with a cloud based application for 6-8 hours where a power source was not available. Upon arrival, I charged the power station fully and stored it in the closet. When I went to use it a few weeks later the power indicated it was at 98%, so I filled it back up to 100% the night prior to using. The next day, I plugged my laptop into the power station and worked continually on the laptop for SEVEN HOURS! The battery pack makes a subtle "whirring" noise when it cycles, but it's not terribly distracting. This battery pack saved my butt so I could work for the entire day. It's handy to move around, I kept it on the countertop next to me (and I had to move from one surface to another several times throughout the day). When I got home that night I charged it back up. It DOES take a while to recharge. I don't think that's a drawback, it's just the way it is. I'm very happy with this purchase!

This is a pretty impressive battery pack (42000mAh) that is great for my laptop or higher energy use electronics. 110V AC output design is nice for all electric device. It’s great if you live in areas that might lose power during storms or if you do a lot of camping. It does a great job at keeping my laptop charged when I am out. It’s well built and durable. Once charged it holds an impressive 42000 mAh which is a lot in such a small device. I get my standard AC plug as well as USB options. It also has a small flashlight and LED light so I know how much power is left.

This battery is definitely a beast. Feels very well built and solid. It is a tad heavy, but what do you expect when buying something like this. It handles charging my phone on the go, along with my laptop at the same time. No issues at all supplying power to my gaming laptop. But I will say, although I am happy that this portable charger actually allows me to plug my laptop brick into it and works, it drained seriously fast. I tried testing it while on the go, to my gaming laptop, connected to mobile hotspot on my iPhone which is on Verizon, and from 100% down to zero took only about an hour or less. It did keep my laptop at 100% the entire time, but that is all the juice it could give. For resource. My laptop is the 2021 Asus Zephyrus G15 which has a 15.6 inch display, Nvidia GTX 3070 graphics card and I was playing an online MMO the entire time. I will do further tests with regular use no games and update my review.

I needed a power station that at least peaked at 150 Watts for my laptop and it has delivered keeping me charged for several hours while even playing games. It fits in my school bag rather well keeping me powered way past my peers. The only downside I can think of is that the fan to keep it cool is rather loud but if I put it under the table while in use it's hardly discernible.
