It smells when charging, since the day of purchase and years later.

The battery connections are not as good as they used to be at APC.

The old 900 was several classes better.

Two years after purchase and it works perfectly. It powers 1 modem/router, 2 access points, 1 switch, and 2 security cameras. It holds up for about an hour and something during a power outage. Very good!

After 12 years of uninterrupted operation, our old apc rs-1500 left us times.
In search of a new machine, I ended up with the apc br-1600mi, the only thing that made me think better was its price.
I added it to my favorites on the skroutz platform and after 2 days, I received a price drop notification in my email.
Without a second thought, I bought it. It took a week to arrive, but the wait was worth it.

Since Saturday 28-11-2020, when it arrived, I have put it into operation
(after charging its batteries with the machine off)
I have also downloaded the control program from the apc website, which allows you to check and adjust several parameters.
In summary, I have to say that the machine is amazing, especially considering the price I got it for, 300€, there is no competition.

Starting off, I have to say that it does an amazing job protecting devices from sudden power outages, while also stabilizing the voltage. This specific one is 750 watts and if it is "loaded" with a device of a few watts, for example 7 watts, it will "hold" it for 5 hours. Similarly, the more devices are connected to it, with their respective watts, the less the battery will "hold". It is sturdy with very good build quality and I highly recommend it, in other words, it is worth its money.
