## Customer Reviews

### ⭐⭐⭐⭐⭐ Must have for power efficiency
*by P***K on March 6, 2025*

You need to print a box to put this into and caution must be used as you are handling wall power when in use. But otherwise this is an excellent addition for a 3d printer that doesn't have auto power off as an included function. There are youtube videos you can look up for guidance on assembly and use.

### ⭐⭐⭐⭐ Not sure about this device
*by O***Y on May 11, 2021*

Well, it works and keeps the printer running for a short while, after power loss.The way this device works is to charge the 9 5 Farad capacitors. I've seen the principal applied in other electronic devices, but internally. If power loss occurs, the circuit puts the stored energy onto the supply line. Basic UPS function. My concern is the power supply. Perhaps a cheap one may not have any protective circuits and feeds energy back into the power supply. Haven't done any research / tests in this regard. I have a Mean Well supply and it would be a pity, if it gets damaged over time.. Right now, all seems well!Because the Mini UPS, puts constantly energy onto the supply line, it may take a minute to deplete the stored energy after the supply is powered off via power switch.It may help with short power losses, e.g. a glitch on your house entry power panel, but at the most for a minute. I believe the idea is just that, enough time during printing to save the current printing position etc.Additional edit:After a few tests, I came to the conclusion that it will, currently, only work if the TFT / Display is in either in Marlin simulation or is a display that only works in Marlin mode.If you use a TFT35 for example, it does not offer a resume print option after power is restored. I added the two ribbon flat, to find out if it would work in Marlin simulated mode. Viola, there was the option to resume print and it actually did finish the test print.Conclusion:On a Bigtree TFT35 in Touch screen mode, It will only be helpful if there is a very short power glitch / outage shorter than a few seconds. The resume print option does, as of now (5/16/21), not exist! in touch mode.

### ⭐⭐⭐⭐⭐ Nice, but DO NOT BOTHER IF YOU HAVE A HEATED GLASS BED!
*by C***E on May 17, 2023*

This thing is really cool!, BUT if you have a printer like a Ender 3 V2 with the heated glass bed that releases the print when it cools down, this....or any "print resume" feature/device, will not work since unless it resumes right away, the print will be loose and not be printable. I guess one could run a pin to a relay on a battery backup just for the bed, but in that case it may be prudent to just get a regular 120v UPS used for PCs etc. You will prob need a big one though depending on how long outages tend to be in your area. If you get brown outs, it should be fine, but if it goes out for hours, it will prob die. Other than
