• Short-circuit safeguards: Immediately cuts off power if a short is detected, reducing fire risk.

These safety features not only protect your batteries but also safeguard your drone, charging equipment, and workspace. For UAV professionals who often charge multiple packs daily, these protections provide peace of mind.

Multi-Port Convenience

Time is valuable, and waiting for batteries to charge one by one can be frustrating—especially in professional operations. With its quad-channel design, the Ultra Power UP-S4AC Drone Battery Charger solves this problem by allowing up to four batteries to be charged simultaneously.

• FPV enthusiasts: Can charge multiple small packs between races without delays.
• Agricultural pilots: Keep several packs ready for spraying missions with no downtime.
• Aerial photographers: Always have backup batteries charged for extended shoots.

Each port is independent, meaning you can charge different types of batteries at the same time. For example, one port can charge a 2S LiPo while another handles a NiMH pack, giving you ultimate flexibility.

Versatile AC/DC Input

Another major advantage of the Ultra Power UP-S4AC Drone Battery Charger is its dual power input capability. Many chargers are limited to either AC (household wall socket) or DC (external power source), but this charger supports both:

• AC input: Perfect for home or workshop charging, where convenience and accessibility matter.
• DC input: Essential for fieldwork, allowing you to connect to a portable power supply, car battery, or generator for on-site charging.

This flexibility means drone pilots don’t need to carry multiple chargers for different environments. Whether at home, in the field, or on the move, the Ultra Power UP-S4AC Drone Battery Charger adapts seamlessly.
