Tuncmatik TSK5264 Nano UPS (Modem Ups)

**** The Tuncmatik TSK5264 Nano UPS has garnered a mixed reception from customers who primarily use it for modems. Many users have reported that the UPS effectively maintains power during outages, allowing their modems to function for several hours without interruption. For instance, one reviewer noted that their ZyXEL 3625 modem operated seamlessly for 4 hours during a power cut, demonstrating the device's capability in maintaining internet connectivity during unexpected electrical failures. However, not all feedback is positive. Some users have highlighted issues, particularly regarding power fluctuations that lead to intermittent disconnects, which were not experienced when using the standard adapter. This raises concerns about the UPS's effectiveness in mitigating power instability. Furthermore, several customers critiqued the product for inadequate product descriptions, with misleading images and the absence of essential features like a voltage selector switch, which many expected. The ergonomics were also criticized, as the device's size makes it challenging to plug into multiple outlets easily. Despite the mentioned drawbacks, users have generally commended the UPS's reliability, asserting it performs well when it comes to providing backup power. Concerns about the device routing power have arisen, especially regarding compatibility with the modem's requirements, including a call for more detailed specifications on battery life and capacity. Quality concerns were voiced after a user reported a malfunction within a year, exacerbated by the company's restrictive warranty service policies. Overall, the Tuncmatik TSK5264 Nano UPS can be a valuable solution for modem power backup, provided potential buyers are aware of its limitations regarding compatibility and underwhelming customer support. **
