DC1018L Mini UPS 5V 9V 12V Battery Backup for Router & Modem
Keep Your Network Running — Even During Power Outages
The DC1018L Mini Uninterruptible Power Supply (UPS) is a compact, intelligent backup power solution designed to keep your router, optical modem, network switch, or CCTV monitoring system online when the mains power goes out. With three selectable output voltages — 5V, 9V, and 12V — and support for replaceable 18650 lithium batteries, it delivers flexible, reliable standby power exactly when you need it.
⚠️ Important Notes:
- Batteries are NOT included. You will need to supply your own 18650 lithium batteries (4 cells required).
- First-time activation: The power cord MUST be connected to a mains supply on first use to activate the unit. The UPS cannot be started from battery alone without this initial activation step.
