Stuck with sluggish 5V/10W charging from your two-wheeled EV, or worried about aftermarket chargers getting fried by sudden voltage spikes when plugging in? CXW has the answer with its CX8901X-PD65W integrated high-voltage fast charging solution.
Built around their proprietary CX8901B high-voltage asynchronous buck controller and CX2919C multi-protocol IC, it delivers a massive 30-120V wide DC input and a 65W PD/PPS output.
Real-world testing by ChargerLAB proves this hardware excels across efficiency, compatibility, ripple suppression, and thermal performance, hitting the sweet spot for high-voltage EV and portable power station charging needs.
The CX8901X PCB sports a clean layout featuring strict isolation between high and low-voltage zones. Flip it over, and you'll find extensive exposed copper paired with three isolated cooling zones to keep things cool under heavy loads.
The input end uses a JerCap 100V high-voltage aluminum electrolytic capacitor, leveraging a robust 120V peak tolerance to shrug off the violent transient voltage spikes common during battery hot-swapping.
Protocol support is extensive, covering QC2.0/3.0, FCP, AFC, PD3.0, PPS, DCP, and Apple 2.4A, backed by standard 5V to 20V fixed rails and a flexible 5-21V PPS span.
Testing confirms steady step-down and 63W+ output across 48V, 60V, 72V, and 99.5V input rails. Conversion peaks at an incredible 95.49% under simulated 30V input, staying north of 91% at higher voltages. Running a heavy 20V/3.25A load for an hour at 25°C room ambient yields peak board temps of just 57.3°C on the front and 52.8°C on the rear.
Packing wide-voltage conversion, high-voltage surge protection, and full protocol support into a feather-light 20g package, the CXW CX8901X redefines what's possible for on-the-go EV power.
It smashes the old charging bottlenecks, offering laptop-tier fast charging right from your ride. As the EV market shifts toward higher voltages, smart lithium architectures, and global export markets, rugged, thermally efficient DC-DC solutions like this are set to become the gold standard for integrated vehicle power upgrades.
