CUKTECH20 Power Bank, 140W 25,000mAh Portable Laptop Charger, 3-Port, Smart TFT Display, PD3.1 PPS Protocol Battery Pack for MacBook Pro/Air, Surface Pro, iPhone 15/14, Samsung S24, iPad and More

Not quite 100wh, but still. 88wh/90wh *rated/typical. Fancy device. Comes with a quality 6amp cable. I got it for around $89 and that's a fair price for what you get.Seems like there are 5 cells in this thing. My feelings on that are that we're pushing the boundaries a bit at these powers and storage estimations. However, the features make up for it. But, that's 1.2 to 1.5a per cell at full tilt, so probably fine. High powered Flashlights are meaner :)My favorite 100wh battery right now is my sharegeek storm2. However, we had a rough start, and there are still some day to day things that annoy me about it. I would purchase this at discount, vs the shargeek at discount (depending). Also I didn't like shargeeks direct mail marketing to me :/ cuktech, I've never heard of which is why I checked them out.I can see the charge state! Yes, this device makes good use of screen real estate. I can actually view the state of charge :) In fact, overall the layout and usage of the screen is well thought out IMO.Each input/output has it's own gauge, with watts amps volts. This is helpful. Estimated runtime, and a big state of charge percentage. Viewing it all through a matt plastic cover, which is a little weird, but still viewable.On screen 2, totals are being graphed, over a 3 or 5 minute period. So when you swap there, you see some immediate history, as well as live data for the three ports.In my testing, each port stayed nailed up. This is a subtle and thoughtful feature. It means you won't accidentally power down your other device, just because you started charging your cell phone, or charging the battery bank. fwiw, the cuktech 40 doesn't behave this way.Something bad, is that it may not always be possible to charge something else. What I mean is that both usb-c ports are input/output ports. So if you had another device, that is an input/output device, you may have trouble negotiating the charge in the direction you intend. It would have been nice, if one of the USB-C ports wasn't also an input port.....The cucktech 20 will build up heat. It may not accept a charge until this heat has dissipated. This happened to me after it went from 60-14% discharging at 133w. Impressive. However it means that the device doesn't get rid of heat well. It looks like there is a heat sink in there. But really it's kind of a heat "pit", because It can fill up. The entire outside is plastic, so the heat doesn't dissipate fast. So yeah, I couldn't charge it up when it was at 14%. It eventually continued to charge at a de-rated speed (50w) after about ten minutes. This is a feature. However better heat dissipation would have been better.For the price I paid, I'm keeping it. Its a good example of what a battery like this should be. It's a little large for the capacity, it probably should have been born with 8 cells, and better heat management. But I still like it. And the screen is really well thought out IMO. Hopefully I won't discover any stupid behavior. I've only had it for like 24 hours. My concerns are lockups *but it appears you can reset it by long pressing the power button, just make sure nothing else is plugged into it. My other concerns are self discharge. But it still thinks it's at 100% 12 hours later. So decent enough start.I tend to update reviews long term. So if there is anything of interest I'll certainly complain about it, or sing it praises. Otherwise, this is an accurate review.

Amazon asked me to add the customer review. I will absolutely add it to customer review. I was going to buy a cuktech 300 watts 40,000 mah. I found out that it was too expensive than what I was going to pay for. I have been doing lot research about steam deck wattage. I have learned that the steam deck can climb up to 150 watts but at same speed. I was so surprised! I had others battery banks as well. First battery bank was the baseus 65 watts 30,000 mah. I gave those to my wife for using the Nintendo switch on her end. I decided to buy another battery bank but it was only for playstation 5 controller. So I ordered a 30 watts 40,000 mah only for the playstation 5 controller but I was able to use it for the steam deck. I wasn't able to use it for steam deck because it did work fine for small games but it didn't work for football game like madden NFL 2023. It would drain like 50% or 52% of the battery bank 30 watts 40,000 mah. I was like forget it. I am going to buy bigger capacity and bigger wattage. I was this close ordering a baseus 100 watts blade 20,000 decided not to buy it. After I did more research for steam deck battery support. I decided to purchase cuktech 210 watts 25,000 mah.The cuktech 210 watts 25,000 mah is awesome battery bank! Just remember when purchasing the battery bank always look at the wattage and PD 3.1 version. Here is why...... The higher wattage that you go will slow down the battery bank. If you use the lower wattage like 30 watts will tear your battery out fast and recharge the battery bank life span won't last as long.I would recommend to anyone who needs laptop charging and steam deck capability to 3.1 PD and 210 watts. Also you will need to buy your own charger either a 65 watts or 100 watts or 160 watts PD 3.1 to recharge the battery bank itself. I also have learned that the cuktech 210 watts 25,000 has a pass through charging. It is perfect for travelers and home use and friends and family and in laws visit. The battery bank 210 watts 25,000 mah works well with steam deck playing with madden NFL 2023. It only drains 15 to 16% for 6 minutes each quarter for only entire one full game. I can get that battery bank to last for days. That is all I need to say.

Charger worked great. Charging, powering multiple devices, phone, earbuds, laptop - all your digital goodies. However after a few weeks the screen failed. If you look at the pictures I took you can see the screen is 100% scratch free, smooth, exterior intact, yet no longer legible It appears as if it’s been smashed like dropped or something. The problem is that it wasn’t dropped and the exterior of the device is 100% flawless. Zero physical damage to the surface, nothing. Yet the screen has failed completely and it is no longer intuitive as it was originally. It still charges and powers devices but I no longer have any idea the status and details. I reached out to the seller via email per Amazon directive to see if I could get it repaired or serviced. Considering the price I don’t want to throw it away, it’s not exactly disposable but the seller never responded so I’m stuck with this expensive - no longer intuitive - power supply/paper weight. I think mine is defective, but it did work great for a short time. Keep that in mind when you are scrolling reviews.
