Why will my AmazonBasics B073Q48Z95 UPS not turn on?

If your AmazonBasics UPS won't turn on, there could be several reasons. First, the on/off switch has a built-in delay to prevent damage from rapid cycling; turn the UPS off, wait 10 seconds, and then try turning it on again. Second, make sure the UPS is properly connected to a 110/120 V 50/60 Hz outlet. Third, the frequency may be outside the operating range of 47-63 Hz; in this case, turn the UPS off, verify the frequency is within range, or try turning it on in battery mode. If none of these steps work, it is possible that the battery is worn out or there is a mechanical problem, and you should contact Amazon.
