What to know before buying

Listing details to confirm

The title and feature details give an inconsistent power picture: 1200W total is claimed, while the stated 800W alternator and 600W solar inputs sum to 1400W. Treat the inputs as separate maximum claims, not a confirmed simultaneous total. The 13× faster claim has no stated comparison conditions. The listing describes vehicles with 12V or 24V starter batteries but lists input and output voltage as 12 Volts (DC). Third-party compatibility is limited to most units and may require voltage adjustment in the app. D+ signal cables are user-supplied, and the manufacturer says battery-detection sensitivity varies by vehicle, so check shut-off behaviour during first use. The title's emergency jumpstarter wording refers to reverse charging through a compatible power station or battery pack.

Who is it for?

A good fit for

Van, RV and road-trip users seeking to charge a portable power station from the vehicle while travelling.
Buyers who want a vehicle charging unit with a solar input and already use compatible MC4-connected equipment.
BLUETTI power-station owners interested in the described reverse-charging and battery-maintenance functions.

Less suited to

Electric-vehicle owners, as the listing says the charger is not compatible with EVs.
Buyers who need a charger with D+ signal wiring included or who require confirmed compatibility with a specific third-party power station.

Frequently asked questions

Can Charger 2 charge a third-party power station?

The listing says it works with most third-party portable power stations, including compatible units with MC4 connectors. It also advises adjusting the voltage in the BLUETTI app when changing stations. Check the exact station's requirements before use.

Does the package include D+ signal wiring?

No. The listing says the D+ signal cable must be supplied by the user and specifies a 2-pin connector with 5.08 mm pitch and 24 AWG.

Can it be used with an electric vehicle?

The listing says it supports vehicles with a 12V or 24V starter battery, including some hybrids with an alternator and starter battery, but not EVs.

Does it jump-start a vehicle on its own?

The described function is reverse charging a starter battery from a BLUETTI power station or battery pack through the BAT port. The listing does not describe a standalone jump-start battery.
