ISDT K2 Air 1000W 20A Dual-Channel AC/DC LiPo Charger

ISDT K2 Air 1000W 20A Dual-Channel AC/DC Smart Charger

The ISDT K2 Air is a powerful and versatile dual-channel AC/DC smart charger designed for RC pilots who want the convenience of a built-in AC power supply combined with significantly higher charging performance when using an external DC power source.

With standard AC power, the K2 Air provides up to 200W total charging power. Connect it to a suitable DC power source and output increases to as much as 500W per channel / 1000W total, with charging current up to 20A per channel.

Two independent charging channels allow you to charge two batteries simultaneously with different settings, while built-in wireless connectivity works with the ISDLink App for remote monitoring, task setup, and OTA firmware updates. A bright 2.8" IPS color display provides a clear and intuitive interface whether you're charging at home or at the flying field.

Key Features

• Dual-Channel Charging – Two independent channels allow simultaneous charging of two different battery packs.
• AC & DC Input – Use standard 100–240V AC power at home or connect an external 10–30V DC power source for substantially higher charging output.
• Up to 1000W DC Charging Power – Delivers up to 500W per channel when powered by a suitable DC source.
• Up to 20A Per Channel – High-current charging capability for demanding RC battery applications.
• 6S Lithium Battery Support – Supports LiPo, LiHV, LiFe and Li-Ion battery packs from 1S to 6S.
• Wireless App Control – Connect to the ISDLink App to monitor charging, preset tasks and perform OTA firmware updates.
• 2.8" IPS Color Display – Wide 178° viewing angle with excellent visibility, including outdoor use.
• High-Current Cell Balancing – Up to 1.5A balance current per cell.
• Multiple Battery Functions – Charge, discharge, storage, balance and battery destroy modes.
• Parallel Mode – Allows both channels to work together when additional charging output is required.
• USB-C Output – Provides up to 30W output for compatible USB-powered devices.
• Built-In Safety Monitoring – Includes abnormal battery-voltage and incorrect cell-count alarms.

Specifications

*ISDT's current K2 Air product specifications list parallel charging at 800W/35A. Maximum charging performance depends on input voltage, available DC power, battery configuration and operating conditions.

🚁 Why We Like It: The K2 Air gives RC pilots the best of both worlds. Plug it directly into an AC outlet for convenient everyday charging, or connect a powerful DC supply to unlock up to 1000W of total charging power. Its dual independent channels, 6S capability and wireless monitoring make it an especially practical charger for pilots running multiple helicopter battery packs.
