Which type of UPS is better?

Offline UPS, also known as standby UPS or battery backup, is a cost-effective option. A better offline UPS system switches to the battery fast enough to prevent power supply anomalies and short interruptions. Offline UPS can prevent most spikes, but it cannot maintain perfect power during slight dips and surges.

The key to the quality of offline UPS is the power range of the device before switching to the backup battery. If the range is wide, the battery consumption will be smaller, and the backup time will be longer when the power is cut off. The longer the UPS switches to the backup battery, the shorter the battery life will be

The offline UPS technology will protect most power spikes by suppressing the over-voltage, and help overcome more than 90% of all interruptions. The offline UPS system will directly pass the public AC power through the unit and switch through the conversion to reach the output point of the protection load.
