Immediately after plugging in a very loud sound of a fan that is a little harder or defective. Insufficient production control and unnecessary moving of the box back and forth due to complaints.
Fan defect

I bought it for the purpose of maintaining power as a UPS during a power outage for two NAS storage devices, a room security system, 3 Eufy IP cameras, Internet, switch - TPLINK, TPLINK wifi network extension, laptop connection and I am satisfied. It's a pity that the classic sockets don't have an extra socket, but that's a small thing
Display brightness
battery life at least suits my needs
Allows it to be used as a UPS
looks good
the display does not shine all the time after a few minutes it turns off does not bother the luminosity in the evening
Quickly charges from 0 to 100 percent in about an hour and a half
USB and USB-C 2x for phone charging
It will also power my PC with one monitor, I have not tested it yet
When charging a little fluctuating fan hum but it does not bother
Too bad you can't connect the same unit to each other some backup power supplies can do this
It won't pull the kettle overload and the backup power goes down but it's not a priority for me
Too bad it doesn't have a classic socket at the back of the unit on the side

Hello, the cage, it works, but for the ignorant person after the first unpacking, the problem is that it "does not know" its own capacity, as if it did not pass some output test-calibration; the calibration is not a simple thing, it takes a long time - but if you connect it to the mains and leave it charging overnight, even though it says it has 50% after a few minutes(! ) on the network it reports 100% (nonsense) and when you try to discharge it, it's "empty" after a while, it's because the FW inside doesn't know the real capacity of the battery (it's stupid to determine the LiFePo4, it's almost UNrecognizable on the voltage), it's NECESSARY to charge it to the maximum after unpacking, LONG, overnight, then give it some moderate load, 30W, some fan, something, and again, LONG enough to let it slowly discharge like that until zero-off - the BMS inside will "learn" the discharge curve and start counting how much energy "came out" of the battery when discharging and how much "went in" when charging - otherwise it can't even count (and over time this can even get out of whack, it may not be an accurate measurement under heavy loads in particular - i.e. then repeat the calibration if it seems to be losing capacity. it can't LiFePo4 must last an awful lot - but simply the charging and discharging curve must be trained. I've charged it like this (300W fast from AC) and discharged it (30W slow) about 3 times better to make sure it's somehow "sane", the % state. That's it.
nice small, lightweight, ok for first play with solar panel - XT60 to MC4 cable included
after unpacking at least my piece does not have the battery status in BMS, see description
