DJI WB37 Battery Charging Hub (USB-C)
The DJI WB37 Battery Charging Hub (USB-C) is a two-bay charging dock for the WB37 Intelligent Battery, the pack that powers the RC Plus, Cendence, FPV controllers, CrystalSky and High-Bright monitors, the DJI Video Transmitter and Receiver, and the D-RTK 2 mobile station. It accepts power over USB-C with Power Delivery, so any FCC-certified 55 W or higher USB-C PD charger (DJI's 65 W Portable Charger included) can drive it. The hub charges two WB37 packs in sequence from highest state of charge to lowest, and runs a full charge on a single battery in approximately 66 minutes when paired with the DJI 65 W charger.
Two-bay WB37 charging hub. USB-C Power Delivery input, sequential charging, 66 minutes per battery on a 65 W PD source.
Features
- Charges up to two DJI WB37 Intelligent Batteries from a single USB-C Power Delivery source, in sequence from highest state of charge to lowest, so the most-ready pack is online first
- USB-C input accepts DJI's 65 W Portable Charger or any FCC-certified third-party USB-C PD charger rated at 55 W or more and 3.7 A or more for optimal charging
- Approximately 66 minutes to fully charge a single WB37 when paired with the DJI 65 W Portable Charger (tested at 25 °C, used as reference)
- Per-bay status LEDs show charging state at a glance: fast charging, normal charging, fully charged, and abnormal conditions including battery faults and out-of-range temperatures
- Compact and light at approximately 108 g, easy to add to a field kit or pelican without adding meaningful weight
- Works with portable USB-C PD power sources in the field, so the same hub used at the office charges off a vehicle inverter, portable power station, or laptop-class USB-C PD wall charger when traveling

Compatibility
The hub charges the DJI WB37 Intelligent Battery. The WB37 powers a wide range of DJI ground-side equipment, so the hub fits into any workflow built around those devices:
- DJI RC Plus and RC Plus 2 Enterprise remote controllers
- DJI Cendence remote controller
- DJI FPV Remote Controller
- DJI CrystalSky 5.5" and 7.85" monitors
- DJI High-Bright Remote Monitor
- DJI Video Transmitter and Video Receiver
- DJI D-RTK 2 High-Precision GNSS Mobile Station
- Aircraft workflows that ship with WB37-powered controllers, including the DJI Matrice 350 RTK, Matrice 300 RTK, Inspire 3, and Inspire 2
Who this is for
- Operators carrying two or more WB37 packs who want both spares charging in parallel between shifts without managing two separate chargers
- Public-safety, inspection, and survey crews running long days where controller and monitor downtime is a real cost
- Fleet operators standardizing on a single WB37 charging solution across multiple DJI platforms
- Field crews who want to charge WB37 packs off the same USB-C PD power source (wall charger, vehicle inverter, portable power station) used for laptops, phones, and tablets
What's included
- 1 × DJI WB37 Battery Charging Hub (USB-C)
Please note: The hub does not include a USB-C charger or cable, and the WB37 batteries themselves are sold separately. For optimal charging time, use the DJI 65 W Portable Charger or an FCC-certified USB-C Power Delivery charger rated for at least 55 W and 3.7 A. Lower-wattage PD chargers will work but extend the charge time.
FAQ
How many batteries does this charge?
Two DJI WB37 Intelligent Batteries per hub. The hub charges them in sequence based on state of charge, starting with the pack that has the highest charge and finishing with the lowest. The status LEDs above each bay show which battery is currently charging and which has finished.
Does it charge both batteries at the same time?
No. The hub charges sequentially rather than in parallel, which is what allows it to operate from a single USB-C PD power source without requiring a high-wattage adapter for every bay. The first battery finishes in roughly 66 minutes (on the DJI 65 W charger), then the second begins.
What charger do I need?
The hub accepts any FCC-certified USB-C Power Delivery charger. DJI recommends the DJI 65 W Portable Charger, which is sold separately and produces the 66-minute single-battery charge time documented by DJI. A third-party USB-C PD charger of at least 55 W and 3.7 A will also work; below that rating the hub still charges but takes longer.
Can I run it from a portable power station or vehicle inverter?
Yes, as long as the source provides a USB-C Power Delivery output that meets the recommended 55 W / 3.7 A minimum. This is part of why the USB-C form factor is useful: the hub can run from the same portable power station, vehicle USB-C port, or wall charger that powers laptops and tablets in the field.
Will it work with older DJI batteries (TB-series flight batteries, BB30, etc.)?
No. The hub is built specifically for the DJI WB37 Intelligent Battery. DJI's user guide is explicit that the hub should only be used with the specified WB37 pack. Aircraft flight batteries use dedicated chargers and stations sized for their voltage and capacity.
What do the status LEDs mean?
Each bay has its own LED array. LEDs blinking quickly in sequence indicates fast charging; blinking slowly in sequence indicates normal-rate charging; solid LEDs indicate the battery in that bay is fully charged. The hub also reports abnormal states: communication faults, battery faults, and out-of-range temperatures, each with its own blink pattern documented in the DJI user guide.
What's the operating temperature range?
5 °C to 40 °C (41 °F to 104 °F). Outside that range the hub will pause charging until the battery and hub temperatures return to normal. In cold-weather operations, let the batteries and hub stabilize toward room temperature before connecting them.
