Choosing among FPV radios & batteries comes down to a basic split: do you need to charge DJI FPV packs, or replace a LiPo battery with the right electrical and connector setup? The four choices here separate cleanly into two DJI charging products and two HRB battery products. Match the job first, then use the listed price as a tie-breaker.
Quick take
Treat these as two different shopping decisions rather than four interchangeable choices. The DJI FPV Battery Charging Hub is for expanding a compatible DJI charging setup, while the DJI FPV Drone Battery Charger AC Power Adapter is the adapter component. The two HRB items are LiPo battery choices with different cell and connector formats.
- Need multi-battery charging? Start with the DJI FPV Battery Charging Hub.
- Need an AC power adapter? Start with the DJI FPV Drone Battery Charger AC Power Adapter.
- Need an HRB battery? Compare the XT90 and EC5 formats against your required setup.
Listed-price comparison
Prices span USD 29.99 to USD 93.99, creating a $64.00 gap between the lowest and highest entries. The charging products occupy the lower end of the range, while both battery choices carry higher listed prices.

Product notes
DJI FPV Battery Charging Hub
Choose the Genuine DJI FPV Battery Charging Hub when your priority is expanding a DJI FPV charger for multiple batteries. It can add three additional batteries and charge them in sequence, with an approximately 55-minute charging time subject to temperature. The black DJI unit is compatible with DJI FPV and is described as open-box. That condition is the key limitation versus the new charger below, so it suits a shopper who specifically wants hub functionality and accepts an open-box item. At USD 36.80, it sits near the lower end of this group, but it still needs a compatible DJI charger rather than replacing the AC adapter.
DJI FPV Drone Battery Charger AC Power Adapter
Pick the Genuine DJI FPV Drone Battery Charger AC Power Adapter when the immediate need is an AC power adapter rather than a multi-battery hub. Model CDX170-90 is paired with a 25.2V, 3.4A, 86W specification and includes a power cord; the product is marked new. Its main limitation is scope: it is the charger/adapter component, while the separate charging hub is the item that expands a DJI FPV charger to three additional batteries. The USD 29.99 price is the lowest in this comparison, making it the direct route when the adapter format and CDX170-90 model match the setup. It does not provide the hub role.
HRB XT90 LiPo Battery
Go with the 2pcs HRB XT90 4000mAh 6S LiPo Battery if your setup calls for a pair built around a 6S, 22.2V configuration and an XT90 female plug. The battery is identified with 4000mAh capacity, a 7PINS JST-XH balance connector, and a 100C continuous discharge rate; CE, ROHS, MSDS, and UN38.3 certificate designations accompany the stated specifications. The limitation is fit specificity: the connector, voltage, and dimensions need to match the aircraft or vehicle. At USD 93.99, it is the highest-priced choice here, so it makes sense when those 6S and XT90 requirements are the reason you are shopping.
HRB EC5 LiPo Battery
Choose the 2x HRB 5200mAh 4S 14.8V EC5 LiPo Battery for a setup using EC5 connectors. The pack specification combines 5200mAh capacity, 14.8V per pack, a 100C continuous discharge rate, and a JST-XHR-5P balancer connector; CE and ROHS are listed certificate designations. Its limitation is the electrical and connector format: shoppers needing 6S, 22.2V, or XT90 should choose the other HRB battery instead. At USD 79.99, it falls between the two DJI charging products and the 6S HRB battery in listed price. This is the relevant route when the 4S/EC5 combination, rather than a charger, is the actual requirement.
Final recommendation by use case
- Multi-battery DJI charging: Choose the DJI FPV Battery Charging Hub because its hub role expands a connected DJI FPV charger.
- DJI AC charging: Choose the DJI FPV Drone Battery Charger AC Power Adapter CDX170-90 for the adapter role.
- XT90 battery connection: Choose the HRB XT90 LiPo Battery when its connector, voltage, and dimensions match your setup.
- EC5 battery connection: Choose the HRB EC5 LiPo Battery when its electrical configuration and connector match your setup.
If you are deciding between the two DJI items, choose by function: expansion points to the hub, while the AC component points to CDX170-90. For the HRB choices, connector and electrical setup should decide before the price gap does.
