More than a vehicle charger

Charger 2 is designed to manage power flow between your vehicle, solar panels, compatible BLUETTI power stations, and supported DC loads. It can automatically balance input and output while giving you control over how your mobile power system behaves.

BLUETTI Charger 2 connected to vehicle battery, solar panel, portable power station, and expansion battery

Built for rolling power systems

Whether you are topping up a power station while driving, adding solar at camp, or building a cleaner DC setup in a van or RV, Charger 2 keeps the system simpler by putting charging, monitoring, and control into one central unit.

BLUETTI app controls for Charger 2 modes, reverse charging, connected model detection, and system status

Set charging around the way you travel

Use smart scheduling and app-based controls to manage how Charger 2 charges and supports your system. It is made for people who do not want to manually swap cables every time the road, sun, or load changes.

BLUETTI Charger 2 compatibility with BLUETTI portable power stations and other supported models

Top up your power station from the vehicle or solar

Charger 2 works with BLUETTI power stations and most other power stations that support compatible solar-style charging input, giving road-trip and mobile users a more flexible way to keep batteries charged.

BLUETTI Charger 2 reverse charging and starter battery support feature overview

Reverse charging for starter battery support

Battery Link technology allows Charger 2 to reverse-charge the vehicle system in supported modes, helping keep the starter battery supported through jumpstart, trickle, and pulse-style charging options.

Cleaner 12V/24V power for mobile essentials

With the DC Hub, Charger 2 can support dual-voltage DC output for items like lights, fans, fridges, and other compatible 12V/24V devices, reducing the need for extra boost modules and messy wiring.

Fast dual-input charging

Charge from the alternator, solar, or both

Instead of relying on a slow 12V car outlet, Charger 2 can pull charging power from your vehicle and solar panels. Use one source when that is all you have, or combine sources when you want to recover battery capacity faster during long travel days.

Recover power while you drive

Alternator charging is the road-trip advantage: drive to the next site and use that travel time to recharge your compatible power station instead of waiting around at camp.

Add solar when you park

When the vehicle is parked, solar input helps keep your battery system topped up from clean energy. It is especially useful for vans, RVs, work trucks, and off-grid camps that sit in one place for hours or days.

Use both without constant cable switching

Charger 2 is built so the vehicle and solar side can work together without constant unplugging and switching. That makes it easier to keep a mobile power system charged while conditions change throughout the day.

Compatibility + DC output

Works across BLUETTI systems and supports cleaner DC setups

Charger 2 is designed for BLUETTI power stations and broad compatibility with many third-party models. Pair it with the DC Hub when you want direct 12V/24V output for compatible vehicle and camping devices.

Frequently Asked Questions

Clear answers to common questions about this product, setup, compatibility, and use.

Q1: When should I use Reverse Charging or Maintenance Mode? Reverse Charging quickly tops up a depleted or low car battery in an emergency, while Maintenance Mode provides a low-current, continuous charge for daily battery care. Q2: Will installing the CHARGER 2 affect my vehicle's warranty? Check with your vehicle manufacturer before installation to make sure it won't void your warranty. Q3: How should I maintain the CHARGER 2? Regularly check and tighten the screws, keep it clean and dry, and ensure proper ventilation. Q4: Which vehicle battery can power the CHARGER 2? Standard 12V or 24V vehicle batteries, or two 12V batteries connected in series. Q5: Should I disconnect the CHARGER 2 during long periods of inactivity? Will it drain my car battery? Disconnecting is recommended for battery protection. It stops drawing power 3-6 seconds after the engine turns off and shuts down after about 30 minutes to prevent over-discharge. Left connected, it consumes very small idle power with minimal impact. Q6: Is there a power limit when charging from the car starter battery and solar simultaneously? Yes. Charging power is limited to 1,200W. Q7: What's the maximum charging power from the car starter battery? 800W. Q8: Can I charge multiple devices at the same time? Yes. Q9: How do I set the CHARGER 2's charging power? CHARGER 2 Charging Power = Alternator Output Current × Car Battery Voltage (12V/24V) ÷ 2. Example: to reach full charging power (800W) from a 12V car battery, use an alternator rated 133A or higher. Q10: Will the CHARGER 2 damage my vehicle battery or shorten its lifespan? No. It continuously monitors battery voltage and adjusts charging power in real time, automatically stopping if voltage drops below 12.0V (12V systems) or 24.0V (24V systems) to prevent over-discharge. Q11: What is Smart Detection? Does it work with all BLUETTI portable power stations? Connect the CHARGER 2 to a BLUETTI portable power station and select Smart Detection in the app — it automatically detects the device and sets the optimal input voltage. Q12: Why can't I enable or use Reverse Charging? It's available when the vehicle battery drops below 12.6V and stops automatically once voltage rises above that level. Q13: What happens if the input power exceeds 1,200W? The CHARGER 2 limits total input to 1,200W; any excess power is not used. Solar takes priority up to 600W, with the remainder from the starter battery (up to 800W) or a connected BLUETTI product. Q14: What vehicles work with the CHARGER 2? Any vehicle with a 12V or 24V starter battery, including RVs, vans, and trucks. Q15: Why isn't the CHARGER 2 charging my portable power station while the engine is running? Turn off the engine and verify connections, restart the engine and check the indicator status, and let the engine run a few minutes to charge the starter battery (it won't operate if that battery is too low). Contact BLUETTI Support if the issue persists. Q16: Which portable power stations are compatible? Can it charge third-party models? It supports all BLUETTI portable power stations and most third-party models with MC4 connectors. For third-party models, set the Charging Voltage within the unit's DC input range in Custom mode in the app; charging performance may occasionally be unstable. Q17: Can I connect third-party solar panels? Yes, as long as they have a total Voc of 13V-50V and MC4 connectors. Q18: Can I charge third-party battery packs connected to the BAT port? No. The BAT port supports BLUETTI battery packs only. Q19: How does charging priority work? Set Priority Charging in the app. PPS mode order: DC Hub → Energy Storage System → BLUETTI Battery. Parking Battery mode order: DC Hub → BLUETTI Battery → Energy Storage System. Q20: Do I need to connect the D+ signal wire to the smart alternator? Not necessary — if it isn't connected, just select Standard in the app's Generator Settings for normal operation. Which equipment is verified to work with the BLUETTI 5m DC input Cable? The manufacturer explicitly lists Works with all BLUETTI power stations and 95% of third-party models.. Other models are not established as compatible by this evidence.
