Model overview based on user reviews
The Powercom WOW-300 300 VA is an affordable UPS option, but it has been reported to have serious reliability issues. A user experienced a significant flaw where the unit worked for just over a month, powering a firewall and router. During a power outage, it ran for an hour, completely discharged, and then burned out with a smell of burnt plastic. Fortunately, there was no open flame, but the fuse did not blow, indicating a potential defect in this model. In contrast, another Powercom model, slightly more expensive, has been operating without issues for over six months. This suggests that the problem might be specific to the WOW-300 model.
Pros
Cons
Worked just over a month, powered the firewall and router. When the power went out, it ran for an hour, discharged completely, and burned out; the smell of burnt plastic still lingers. Fortunately, there was no open flame. The fuse did not blow. The second Powercom of a different model, a bit more expensive, has been working for over six months now with no issues, although it also discharged completely. It seems the problem is exclusively with this model. Cheap Unreliable  Dolores: use Powercom WOW-300 few months |
