I’ve been using the Bluetti AC2A since last summer. I never thought it would be possible to get excited about a portable power station, but this one is something special. The crisp, immaculate display; intuitive, human-centered design; and remarkable versatility make this entry-level model an incredible life asset. It has served my family without fail in so many ways, from emergency needs during a power outage to a reliable car buddy that allows me to take a small media studio with me wherever I go.

This year, however, the company has introduced a first of its kind product. Bluetti’s Charger 2 is a unified vehicle and solar smart energy hub that addresses the mobile power management challenges faced by globetrotters, RV and van travelers, and self-reliant adventurers known as overlanders. The key features of this impressive RV-ready system are its integration of high-speed alternator charging with solar input, universal compatibility [95% compatibility with third-party portable power stations and modern smart alternators], a simple plug-and-play operation, and its bi-directional reverse charging capabilities.

“The Charger 2 didn’t start in a lab — it started in the feedback threads and campsites of the Bluetti community,” Illia Zahnitko, Bluetti Global Spokesperson, informed. “We spent years building on the foundation of its predecessor, guided by one simple goal: making clean energy truly effortless for everyone. By tapping into both your vehicle’s alternator and the sun at the same time, Charger 2 bridges the gap to faster, easier on-the-road charging.”

Zahnitko continued, “We kept the installation simple and the compatibility wide open, because we know our users are the real innovators. Whether you’re building a custom RV power system or just looking for a reliable spark off-grid, Charger 2 is designed to scale with your needs. You bring the vision — we’ll bring the power.”

Here are just a few of the impressive features you can find on Bluetti’s Charger 2:

  • Compatible with modern smart alternators (Euro 6 compliant)
  • Protection against overvoltage
  • Protection against overheating
  • Protection against reverse polarity
  • Monitor real-time status (via the updated Bluetti App)
  • Monitor control outputs (via the updated Bluetti App)
  • View energy history (via the updated Bluetti App)
  • Features Bluetti’s smooth, lean, and clean aesthetics

Before we take a closer look at some of the top selling points — what makes this model stand out from other products on the market — it’s important to understand that the Charger 2 is a DC-DC converter. It is not a power station or a battery. The Charger 2 harnesses power from your vehicle’s alternator (starter battery) and the sun to provide remarkably rapid charging and power management for your Bluetti power station, expansion battery, and DC Power Hub.

The Central Brain For Mobile Energy Management

To say this unit is just a charger really doesn’t adequately describe its true capabilities and benefits — how it makes life easier for mobile adventurers. Bluetti’s Charger 2 integrates your vehicle’s starter battery, solar panels, and DC loads, feeding expansion batteries, power stations, and Bluetti’s Hub D1 Power Hub — a plug-and-play solution that provides up to 700 watts of stable DC power to run high-demand appliances. The dual-battery system means intelligent power management that automatically chooses the best way to give you what you need, whether it’s day or night, you’re driving or you are stationary. The Charger 2 handles all this for you so you can enjoy the journey and not worry about power needs.

Rapid Charging

Before the Charger 2, travelers could only take advantage of solar power when their vehicle was parked — daytime driving meant wasted solar energy. Now, with Bluetti’s revolutionary dual-input architecture, you don’t have to turn the engine off to take advantage of the sunlight. You can charge from your vehicle’s alternator and solar panels at the same time. This nearly doubles the charging speed of Charger 1 — Bluetti’s previous model. And it charges 13 times faster than a traditional 12-volt car outlet. This means you can get an incredible amount of power, even if you’re only driving a short distance. According to Bluetti, the Charger 2 is capable of replenishing a 1 kilowatt-hour unit in under an hour. For a standard 12-volt cigarette lighter socket, that task would take over 10 hours.

Worry-Free Operation

Bluetti understands the nomadic lifestyle. Beyond the safety features listed above, the company has incorporated advanced vehicle battery maintenance into the Charger 2. This model has three modes that are designed to prevent a stranded-vehicle scenario. 

  1. Emergency Jumpstart (800W): This mode rapidly recharges a drained starter battery to allow you to jumpstart your vehicle.
  2. Trickle Charging (100W): As outdoor enthusiasts probably know, a trickle charge maintains battery health when your vehicle won’t be used for extended periods of time, such as storage.
  3. Pulse Maintenance (100W): The Pulse Maintenance mode helps protect your battery from a buildup of lead sulfate crystals that can reduce performance and lead to premature battery failure.

Effortless Upgrade

Technology changes fast. It was only a little over a year ago that Bluetti officially released its groundbreaking Charger 1. But don’t stress. That doesn’t mean you pulled the proverbial trigger too soon. For a limited time, Bluetti is running a loyalty upgrade for Charger 1 users. You can get the Charger 2 for just $99 — a $400 savings off MSRP! And even better, the company used the same wiring infrastructure so you can just drop in the Charger 2 with no recabling required. This makes upgrading ridiculously easy.

Exclusive Launch Prices

To help celebrate the release of the Charger 2, Bluetti is offering the following exclusive launch prices [These discounted prices are only available for a very limited time.]:

Standalone Unit: $349 (MSRP $599) 
Loyalty Upgrade: $99 (exclusive offer for existing Charger 1 users)
System Bundles: Starting at $599
