I’ve been doing some deep-dive testing on the BLUETTI Charger 2 and DC Hub in my Ford Transit build (paired with an AC200L). While the hardware specs are solid, I’ve encountered a few bugs that impact some setups.

I would be interested to know if any of these are specific to using with the AC200L and if they are also issues with the Apex 300, B300K, or B500K.

I’m sharing these here so others in the community can voice if they are impacted by these issues or if they have found a workaround or other issues I haven't encountered yet. I'm also documenting these in an ongoing Charger 2 review and AC200L review and also sending detailed feedback directly to the BLUETTI team. If you've found any other bugs or discovered workarounds for these, please let me know!

Bluetooth Connectivity

Charger 2 can enter a state where the unit is powered on and functional, but the app cannot establish a Bluetooth connection. In my testing, holding down the power button for 15 seconds to force a restart did not resolve the issue. The only way to restore the connection was to physically disconnect and reconnect the cable from the ALT port. This is a significant concern for installations where cable access is limited.

Workaround: Ensure any device is disconnected from the P090D connection (BAT), then disconnect and reconnect the cable from the ALT port.

Priority Charging

Charger 2 does not follow the "Priority Charging" app setting when set to "Parking Battery." In testing with an BLUETTI AC200L on the BAT port and an EcoFlow Delta 3 Classic on the CHG port, the unit continued to charge the EcoFlow from the AC200L. This behavior should only occur when "Priority Charging" is set to "PPS" (Portable Power Station). It’s possible the AC200L is also at fault for this issue, but I cannot confirm that since I do not have access to other devices such as an Apex 300 or B300K for testing.

Workaround: Manually unplug the power station or disable charging in the power station’s settings if supported. Otherwise, Charger 2 will continue transferring power until the power station on the CHG port reaches full charge.

Power Station Sleep Mode

The BLUETTI AC200L features an undocumented auto-shutdown that triggers after three hours if the AC, DC, and USB outputs are all disabled. When the unit powers down, Charger 2 loses its source and enters sleep mode, effectively killing power to the DC Hub. To bypass this, you must either enable an output or maintain a significant enough load on the DC Hub to keep the system active. I do not have access to other devices such as an AC300 or B300K for testing to determine if they exhibit the same behavior.

Workaround: On the power station, keep DC or USB power enabled and ensure the DC‑ECO setting is disabled in the app.

DC Hub System Switch Recovery

The DC Hub does not follow its "System Switch Recovery" setting. When set to "Enabled," the device should remember whether the DC output was on or off. Instead, after Charger 2 restarts, the DC Hub always defaults to the off position.

Workaround: Manually turn the DC Hub back on each time it powers up.

DC Hub Output Voltage

The "DC Output Voltage" setting for the DC Hub fails to load within the app. The output is 13.5V when on, but the setting field is blank. Tapping the field results in a loading spinner that never resolves, which is an issue if you need to use the advertised 24V mode.

Workaround: Use a DC boost converter, such as the Daygreen 12V to 24V 25A 600W, to convert the 12V output to 24V from the Anderson port.
