Buying Guide: How To Choose The Right DC To DC UPS
What should you look for when selecting a DC-to-DC UPS for routers and modems?
- Output voltage compatibility: Ensure the UPS provides the voltage your devices require (5V, 9V, 12V are common for home networking gear).
- Power capacity: Higher mAh or Wh means longer runtime during outages. Match capacity to your typical outage duration and device power draw.
- Number of outputs: Consider how many devices you plan to back up at once. Some units offer USB, USB-C, and multiple DC ports in one device.
- Protection features: Look for short-circuit protection, overcharge/over-discharge protection, and thermal management for safe operation.
- Portability vs. capacity: Ultra-compact units are easy to place near a router, but larger units may be needed for longer outages or multiple devices.
- NAS and device compatibility: Some UPS units target NAS or specific devices; confirm compatibility with your gear.
