It draws up to 800W from the alternator and up to 600W from solar panels, and delivers up to 1200W into the power station through its charging output (CHG). Charging starts when the engine runs and stops when you park, so the starter battery is not drained while the vehicle sits.\u003c\/p\u003e\r\n\u003cp\u003eIt also works in the other direction. Its bidirectional power port (BAT) carries up to 1000W to or from a BLUETTI auxiliary battery, a dedicated 48V output (DC Panel) runs a BLUETTI DC Hub for 12V and 24V accessories, and reverse charging can put power back into a flat starter battery. The BLUETTI app sets the charging voltage for your power station and monitors the system over Bluetooth or Wi-Fi. Installation is a wiring job in the vehicle: if you're unsure how it fits your setup, we're happy to help before you buy.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"hb21-spec-grid\"\u003e\r\n\u003cdiv class=\"hb21-spec-card\"\u003e\r\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eCharging Output (CHG):\u003c\/strong\u003e 12V to 56V, 24A, 1200W max\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eAlternator Input (ALT):\u003c\/strong\u003e 12.8V at 62.5A or 25.6V at 31.3A, 800W max\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eSolar Input (PV):\u003c\/strong\u003e 13V to 50V, 20A, 600W max\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eAuxiliary Battery Port (BAT):\u003c\/strong\u003e 19.2V at 52A, 25.6V at 39A or 51.2V at 19.5A, 1000W max\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eDC Hub Output (DC Panel):\u003c\/strong\u003e 40V to 58.5V, 600W max, shared across all the DC Hub's ports\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eReverse Charging:\u003c\/strong\u003e 100W\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eProtections:\u003c\/strong\u003e short circuit, reverse polarity, overcurrent, over-voltage and under-voltage\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eFuse:\u003c\/strong\u003e 75A\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eProtection Grade:\u003c\/strong\u003e IP20\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.59kg\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x D):\u003c\/strong\u003e 265 x 169 x 69.7mm\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"hb21-spec-card\"\u003e\r\n\u003ch3\u003eWhat's in the Box?\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e1 x Charger 2\u003c\/li\u003e\r\n\u003cli\u003e6 x Self-tapping Screw\u003c\/li\u003e\r\n\u003cli\u003e1 x Car Battery Cables\u003c\/li\u003e\r\n\u003cli\u003e1 x 75A Fuse\u003c\/li\u003e\r\n\u003cli\u003e1 x MC4 Input Cable\u003c\/li\u003e\r\n\u003cli\u003e1 x MC4 Output Cable\u003c\/li\u003e\r\n\u003cli\u003e1 x MC4 to XT60 Cable\u003c\/li\u003e\r\n\u003cli\u003e1 x Bidirectional Power Cable\u003c\/li\u003e\r\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0528\/2424\/4410\/files\/bluetti-charger-2-user-manual.pdf?v=1786071356\" title=\"Download the BLUETTI Charger 2 user manual (PDF)\" target=\"_blank\" rel=\"noopener\"\u003eDownload the BLUETTI Charger 2 user manual (PDF)\u003c\/a\u003e\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2-year warranty\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp class=\"hb21-warranty-note\" style=\"margin-top:28px;\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e the DC Hub that the 48V output feeds is a separate product.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"hb21-image-full\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0528\/2424\/4410\/files\/bluetti-charger-2-alternator-solar-dual--hero_2dceb43e-f8ff-4184-b0e2-2bb05acc1850.webp?v=1786511587\" alt=\"BLUETTI Charger 2 feature overview: the alternator charger and smart energy hub, with callouts for 600W DC output via the DC Hub, D plus signal alternator status detection, 1200W maximum output power, dual alternator and solar charging, reverse charging of the starter battery in jumpstart, trickle and pulse modes, and app-based smart control\"\u003e\u003c\/div\u003e\r\n\u003cdiv class=\"hb21-section\"\u003e\r\n\u003ch2\u003eUp to 1200W, From the Alternator and the Sun\u003c\/h2\u003e\r\n\u003cp\u003eThe Charger 2 takes up to 800W from the vehicle's alternator and up to 600W from solar panels, combining them to deliver as much as 1200W into your power station.
