KOSS UPS SYLION S-80E 800VA Runtime review

The KOSS UPS SYLION S-80E 800VA is a light weight Uninterrupted Power Supply unit. Its weigh around 4.24 kilograms with voltage input range 162 to 290VAC. The output voltage range is 220/230/240VAC. Before getting the KOSS UPS i was actually looking for the famous APC UPS as it is proven to last for quite a very long time. However i didn't manage to get the APC as it is quite expensive and doesn't have the digital gauge meter for the low ends model.

The KOSS SYLION S-80E 800VA on the other hands is very affordable and it cost around RM180 from PC-Image Wisma Saberkas. However the main reason to get the KOSS is the Digital Gauge meter which is very useful to monitor the UPS battery performance. It has Load level indicator, low battery indicator, and load output indicator as shown below.

Here is the test procedure and results using the KOSS SYLION S-80E 800VA.

1. Belkin Modem
2. Laptop Dell



The UPS battery lasted around 15 minutes to keep the two devices on without plugging to the electricity. The test was run in fully loaded charge of the UPS battery.
