Ideal for photographers, RC hobbyists, technicians, and rechargeable battery users. - 【Supports Multiple Rechargeable Battery Types】 Compatible with Li-ion, LiFePO4, NiMH, and NiZn rechargeable batteries, including common AA, AAA, 10440, 14500, 16340, 18650, 20700, 21700, and 26650 sizes. It also supports compatible 1.5V rechargeable Li-ion batteries after updating to firmware V2.0.0.1 or later. Always select the correct battery chemistry before starting. - 【4+2 Independent Slots with Adjustable Current】 Six independently controlled charging bays automatically monitor voltage, current, capacity, time, and internal resistance for each battery. Charging and discharging current can be adjusted to suit different battery capacities. For smaller batteries or quieter, cooler operation, reduce the current to approximately 0.6A or lower. - 【Color Display & Advanced Battery Data】 The full-color lcd screen clearly shows real-time battery information for every slot, helping you check charging progress and compare battery condition at a glance. Analysis and Cycle modes can measure usable discharge capacity, making C4EVO a practical battery capacity tester for sorting and maintaining rechargeable cells. - 【USB-C Fast Charging Input—Adapter Not Included】 Powered through USB-C and requires a compatible QC or PD wall adapter rated at 18W or higher. A 36W power input is recommended for better multi-slot performance. The package includes the C4EVO charger and USB-C cable; the wall power adapter is not included. Insufficient input power may reduce charging speed or cause unstable operation. - Tips: To ensure compatibility with more battery brands—such as desertcart Panasonic Eneloop 1.5V Li-ion batteries—we recommend updating the firmware via the ISD GO app upon receiving the charger. (*Note: The ISD GO app is currently not supported on macOS systems.) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0799JFWM3 | | Amperage | 3 A | | Brand | ISDT | | Connector Type Used on Cable | USB Type-C | | Current Rating | 3 A | | Customer Reviews | 3.8 3.8 out of 5 stars (118) | | Input Voltage | 5 volts | | Item Weight | 195 g | | Manufacturer | Shenzhen ISD Technology Co., Ltd | | Mfr Part Number | ISDT | | Model Number | ISDT | | Number of Items | 1 | | Number of Ports | 6 | | Output Voltage | 5 volts | | Specification Met | RoHS | | UPC | 843359100270 709046963392 768684806010 | | Unit Count | 1 Count | | Warranty Description | 1 Year | ## Product Details - **Brand:** ISDT - **Input Voltage:** 5 volts - **Item Weight:** 195 g - **Output Voltage:** 5 volts - **Specification Met:** RoHS ## Images ![ISDT C4 EVO Smart Universal Fast Battery Charger Analyzer | AA AAA 18650 21700 Compatible, Capacity Tester Discharger for Ni-MH/NiZn/Li-Ion with Cycle Activate, USB-C Input 1.5V Charge - Image 1](https://m.media-amazon.com/images/I/61uVM737E7L.jpg) ![ISDT C4 EVO Smart Universal Fast Battery Charger Analyzer | AA AAA 18650 21700 Compatible, Capacity Tester Discharger for Ni-MH/NiZn/Li-Ion with Cycle Activate, USB-C Input 1.5V Charge - Image 2](https://m.media-amazon.com/images/I/61Im6E5g6LL.jpg) ![ISDT C4 EVO Smart Universal Fast Battery Charger Analyzer | AA AAA 18650 21700 Compatible, Capacity Tester Discharger for Ni-MH/NiZn/Li-Ion with Cycle Activate, USB-C Input 1.5V Charge - Image 3](https://m.media-amazon.com/images/I/61sgUvakDaL.jpg) ![ISDT C4 EVO Smart Universal Fast Battery Charger Analyzer | AA AAA 18650 21700 Compatible, Capacity Tester Discharger for Ni-MH/NiZn/Li-Ion with Cycle Activate, USB-C Input 1.5V Charge - Image 4](https://m.media-amazon.com/images/I/61NJfkM2-OL.jpg) ![ISDT C4 EVO Smart Universal Fast Battery Charger Analyzer | AA AAA 18650 21700 Compatible, Capacity Tester Discharger for Ni-MH/NiZn/Li-Ion with Cycle Activate, USB-C Input 1.5V Charge - Image 5](https://m.media-amazon.com/images/I/71Lp232Sj5L.jpg) ## Questions & Answers **Q: Why does the charger restart or flash during charging?** A: The C4EVO requires a fast-charging USB-C adapter (PD/QC) with at least 18W output. Low-power adapters may cause restarting, flashing, or unstable charging. **Q: Why does the battery get warm during charging?** A: The default current is up to 1.5A for faster charging, which may cause warmth. For lower heat and longer battery life, we recommend reducing it to around 0.6A. **Q: How do I charge 1.5V Li-ion batteries?** A: Update C4EVO to firmware V2.0.0.1 or later using Windows only. Then manually select “1.5V Li-Ion” mode—not the standard “Li-Ion” mode—before charging. **Q: Can C4EVO discharge or analyze 1.5V Li-ion batteries?** A: No. For 1.5V rechargeable Li-ion batteries, C4EVO supports charging only. Discharge, Analysis, Cycle, and other maintenance modes are not available. **Q: What is Destroy mode used for?** A: Destroy mode safely discharges batteries before disposal. It is designed for damaged or unwanted batteries and is not intended for normal daily use. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/60442109-isdt-c4-evo-smart-universal-fast-battery-charger-analyzer-aa](https://www.desertcart.com.pa/products/60442109-isdt-c4-evo-smart-universal-fast-battery-charger-analyzer-aa) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-08-19*
