COOLM 12V 3A Charger for Jumper Ezbook & Medion Ultrabooks | 36W Power Adapter

Powerful, Flexible Charging for Your Ultrabook Collection

The COOLM 12V 3A Charger delivers a steady 12V output with up to 3A current, a compact 36W max power, and a wide 100-240V AC input. Its center-positive DC plug and 6.6 ft cable ensure a clean, adaptable setup whether you’re at a desk or on the go. This adapter is designed as a reliable replacement for compatible devices without forcing amperage, making it a practical choice for multi-device households or workspaces.

Key specifications help you plan a seamless setup: 100-240VAC input, 12V output, 3A max, 36W, and a DC plug with center positive polarity. The long DC cable reduces the need for frequent repositioning, giving you freedom to place your ultrabook where it’s most comfortable while maintaining a stable power supply.

Compatibility, Safety, and Quality You Can Rely On

This charger is certified with CE and FCC marks, reflecting a commitment to safety and quality. It supports a broad range of devices including Jumper Ezbook 2/3/3S/X3/X4, EZpad 6 Pro, Trekstor Primebook series, Medion Akoya S2218/2217, Chuwi HeroBook and AeroBook lines, and several other Ultrabooks listed in the product notes. It is designed as a confident replacement for 2A or 2.5A adapters when you need more headroom for higher-demand devices.

Safety features are built in to help protect both the charger and your device. Automatic overload cut-off, over-voltage cut-off, automatic thermal cut-off, and short-circuit protection work together to reduce risk during use, while the wide compatibility ensures you can use it with several supported models without changing power bricks.

Important note: Please be aware the adapter does not fit certain models, including Chuwi Hi13, Apollo Lapbook Pro 14", SurBook Mini, Surbook 12.3", Cube MIX Plus, Teclast F5, and F5R. If your prior adapter was 2A or 2.5A, this COOLM unit can serve as a capable upgrade because amperage is not forced.
