Works
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. Read more
