{"product_id":"dji-wb37-battery-charging-hub-wch2","title":"DJI WB37 Battery Charging Hub (WCH2)","description":"\u003cp\u003eThe DJI WB37 Charging Hub (WCH2) is the non-USB-C version of DJI's two-bay dock for the WB37 Intelligent Battery, the pack that powers the Cendence remote controller, CrystalSky monitors, and other DJI ground-side equipment. Unlike the newer WCH3, which runs from a USB-C Power Delivery source, the WCH2 is built to run from DJI's existing aircraft chargers — Inspire 1 and Inspire 2, Phantom 4 Series, Phantom 3, and the matching car chargers — so an operator who already owns one of those DJI chargers can charge WB37 packs without buying additional hardware. The hub charges two WB37 batteries in sequence from highest state of charge to lowest, in approximately 71 minutes per battery, and adds a 5 V \/ 2 A USB-A port for topping up a phone or tablet from the same source.\u003c\/p\u003e\n\n\u003cblockquote\u003e\u003cp\u003eTwo-bay WB37 charging hub for operators with existing DJI aircraft chargers.

The WCH3 runs from any FCC-certified USB-C Power Delivery charger of 55 W or higher, including the DJI 65 W Portable Charger, third-party USB-C wall chargers, portable power stations, and vehicle USB-C outlets.\u003c\/p\u003e\n\n\u003cp\u003eWhen using the Inspire 2 Battery Charger, Phantom 4 Series Charger, or Inspire 2 Car Charger, do not charge the Intelligent Flight Battery (the aircraft battery) and the WB37 at the same time.

The WCH2 (this product) accepts power from DJI's proprietary aircraft chargers at 17.3 to 26.2 V, which is what existing Inspire 2, Inspire 1, Phantom 4, and Phantom 3 owners already have. The WCH3 accepts USB-C Power Delivery input at 5 to 20 V, which works with the DJI 65 W Portable Charger, third-party USB-C PD chargers, and portable power stations. Pick the WCH2 if you already own a compatible DJI aircraft charger; pick the WCH3 if you want to run the hub from a generic USB-C PD source.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhat charger do I need to power the WCH2?\u003c\/summary\u003e\n  \u003cp\u003eOne of DJI's proprietary aircraft chargers within the 17.3 to 26.2 V input range. The full compatible list includes Inspire 2, Inspire 1, Phantom 4, and Phantom 3 wall chargers and car chargers, plus the 57 W Phantom 3 and Osmo chargers (with limitations on simultaneous USB-A use).

The hub charges two packs sequentially, so a fully drained pair takes roughly 2 hours and 22 minutes to fully charge.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhat does the USB-A port do?\u003c\/summary\u003e\n  \u003cp\u003eThe auxiliary USB-A port outputs 5 V at 2 A, enough to charge a phone, tablet, or other USB-A-compatible device while the hub is connected to a compatible DJI aircraft charger. If you're powering the hub from a 57 W Phantom 3 or Osmo charger, do not use the USB-A port at the same time as a battery bay; that charger does not supply enough power for both at once.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eCan I silence the buzzer?\u003c\/summary\u003e\n  \u003cp\u003eYes.

Solid green indicates fully charged. Solid yellow indicates ready to charge. Blinking yellow indicates the battery is outside the 5 to 40 °C operating temperature window.

Outside that range the hub will pause charging until the battery and hub temperatures return to normal.
