Good for a laptop I guess. Not good for 3d stuff
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought these for my home computer and 3d printers. With the specs on these they should handle my 500w 3d printers without an issue. Every time the heat bed starts to warm up the alarm goes off. Also if my computer is doing anything more then office and internet it starts beeping as well. I didn't think it would be an issue unless the power went out.

Posted .These units are not designed to power anything with a heating element as often they cause an in-rush current when starting to heat up, which may overload the UPS. This UPS can handle a total of 650 Volt-Amps of power usage, however the battery outlets max out at 360 Watts. Any more power draw than that and it will overload the UPS, which may be the beeping you are hearing. Thank you for your review!
