T400-3 Mini DC UPS, Batteries Not Included

Prepare a backup power path for a compatible router or modem with a mini DC UPS. It is for users selecting output voltage and fitting the specified battery set.

• ✅ Provide a backup path — The unit switches to a suitable installed battery set.
• ✅ Match a small device — Five-, nine- and twelve-volt outputs serve different approved loads.
• ✅ Replace cells separately — The battery arrangement uses removable 18650 cells.
• ✅ Read an abnormal state — A buzzer and indicator provide a status alert.

Prepare the battery set before relying on backup

The shipment excludes batteries. The 10400mAh description assumes four 2600mAh cells rather than an included pack; match the exact cell requirements and instructions.
