What to do if the AmazonBasics B073Q48YGF UPS will not turn on?
- RRyan MoralesAug 7, 2025
If your AmazonBasics UPS unit isn't turning on, there could be several reasons. First, the on/off switch might be preventing rapid cycling; turn the UPS off, wait 10 seconds, and then turn it back on. Ensure the unit is properly connected to a 110/120 V 50/60 Hz outlet. The battery might be worn out, in which case you should contact Amazon about replacement batteries. There may be a mechanical problem, so please contact Amazon. Finally, the frequency may be outside the operating range; turn the UPS off, ensure the frequency is within 47-63 Hz, or try turning the UPS on in battery mode.
