BLUETTI B300K: Breaking Power Boundaries with BLUETTI

If you're searching for a reliable, powerful backup for home or a solid companion for outdoor adventures, the BLUETTI B300K could be just what you need. This article will explain what makes the B300K unique, its features, and how it stacks up against the B300 model. Whether prepping for unexpected power outages or gearing up for a road trip, we'll help you decide which model fits your lifestyle best.

BLUETTI B300K

What is the BLUETTI B300K?

The BLUETTI B300K is a powerful, high-capacity battery that can store much energy. It is designed for people needing reliable power at home, during emergencies, or outdoors. With a battery capacity of 2,764.8 watt-hours (Wh), it's perfect for running your essential devices and appliances for long periods. This model is built with a particular type of battery called Automotive-Grade LiFePO₄, known for lasting a long time — over 4,000 charging cycles — and for being safer and more durable than standard batteries.

One of the best features of the B300K is its ability to work with other BLUETTI power stations like the AC200L, AC200MAX, AC300, and AC500. This means you can connect the B300K to these power stations to create a more extensive energy system, giving you even more power. For example, suppose you connect it with the AC500. In that case, you can use AC500 to connect 6 packs of B300K batteries and expand your energy storage to a massive 16,588Wh, enough to run larger appliances or power multiple devices for an extended period.

BLUETTI B300K Versatile Compatibility

The B300K also has a built-in USB-A port to charge smaller devices, like phones or tablets, directly from the battery. This makes it handy for both everyday needs and emergencies. Whether you're using it to keep your home running smoothly during power outages or to stay powered up while camping, the B300K is designed to be dependable, easy to use, and versatile enough to fit a range of energy needs.

6. Charging Conditions

Charging Temperature: The battery is best charged in temperatures between 0°C to 40°C (32°F to 104°F). Discharging Temperature: It can be safely used in temperatures from -20°C to 40°C (-4°F to 104°F).

Storage Temperature: The battery should be stored between -20°C to 40°C (-4°F to 104°F) if stored for up to a month, but ideally between -20°C to 25°C (-4°F to 77°F) for more extended storage up to six months.

7. Charging and Discharging Current

Charging Current: The battery can handle a maximum charging current of 60 amps, which can be reduced if charged outside its recommended temperature range.

Discharging Current: When using it to power devices, it can handle up to 70 amps, allowing it to support high-power devices without issues.

If you already have a BLUETTI system, adding the B300K can give you more energy without changing your setup.

Sturdy Build:

The outer case is made from durable materials. This helps protect the battery from bumps or damage and adds to its lifespan. You can feel confident it'll hold up over time, even if you take it on adventures.

Portability:

At around 29.5 kg (65.04 lbs), it's not as light as a small battery pack, but it's manageable for its power and capacity. You might need two hands to carry it or even a dolly cart for easy movement, but its compact size makes it easier to fit in various spaces.

Powerful Battery Capacity:

With 2,764.8 watt-hours (Wh), this battery can keep small to medium-sized devices running for extended periods. This energy can power devices in an emergency, keep a campsite lit, or act as backup power during outages.

Flexible Charging and Fast Recharging:

The B300K can charge up to 80% in 45 minutes when paired with compatible power stations. This means less time waiting to recharge and more time using it. This fast charge makes it convenient in emergencies or when constantly moving.

Standalone Power Source:

The B300K isn't just an add-on; it can also be used independently as a small power hub. With the USB-A port, you can directly charge essentials like phones or tablets, making it a great option even when you don't need to connect it to a giant station.
