Very good overall.
Purchased because the electrical system in my building is dismal, the result is okay; but not perfect.
The positive :
- Stable on electrical voltage.
- Quite complete in terms of sockets: electricity / RJ45. But it supports "only" 3 "backed up" electrical outlets.
- Rather "powerful", because it supports several things: PC / 2.1 sound system / TV / Console Switch / Blu-ray player.
- This inverter offers a battery life of up to 15 minutes.
- An LCD display with audible alarms indicates the status of the UPS.
- The wall-mounting system is very useful.
- Possibility of cold start (in case of power failure).
- Automatic restart of the inverter when power returns.
- A USB socket that can recharge devices.
- A USB communication port that allows remote management of the inverter from the computer (with the use of software).
- The price is correct.
- Two RJ11/45 connectors with effective Tel/ADSL line protection.
- Protection against: Discharge / overload / overvoltage + Tel/ADSL line
- Fast charging time: 90% in 6 to 8 hours (after full discharge).
Negative:
- The regulation of the electric current sometimes lacks responsiveness. A pity.
In short:
It's very good overall.
