Bluetti’s Apex 300 portable power station + B300K expansion battery bundle is currently discounted by a whopping $1,400 on the Bluetti official online store and Amazon for a limited time. The Apex 300 boasts 2,764.8 Wh of storage capacity and supports parallel expansion tech and solar charging.

The Bluetti Apex 300 power station expansion battery bundle is currently discounted at the company’s online store and Amazon for a limited time. To be more exact, you can save $1,400 off the original retail price of $4,098, and the company is also offering an extra 10% off with the BLUETTIAPEX code—that’s a massive 44% discount. This means you can buy the Apex 300 + B300K battery expansion bundle at $2,294.88 rather than the list price of $4,098. 

At Amazon, you can also save 44%, bringing the bundle’s price down from $3,899 to $2,183 once you apply the $1,200 on-page coupon and an extra 10% off code. Additionally, consumers can also take advantage of the 30% federal tax credit, which generally applies to energy storage systems with a capacity of over 3 kWh. 

The Apex 300 portable power station has a 2,764.8 Wh capacity and 3,840 W output. When paired with the B300K battery expansion pack, the Apex 300 offers a maximum capacity of 5,529.6 Wh with 7,680 W surge power, enabling it to power 99% of home appliances, including refrigerators, laptops, coffee makers, and washing machines, according to Bluetti. 

The main highlight of the Apex 300 is that you can scale the power station to a total of 58,000 Wh capacity with B300K expansion batteries while delivering a maximum output of 11,520 W, thanks to parallel expansion tech. Thanks to the company’s TurboBoost fast-charging technology, you can charge the power station from 0 to 100% in just 65 minutes. Alternatively, you recharge the gadget using 2,400 W solar panels in just one hour. 

Our review of the Apex 300 was pretty positive. In our review, we praised the unit for its performance and enormous expandability. However, the power station does require USB ports for charging smartphones and laptops, which is rather displeasing for sure. Please read our in-depth hands-on review for further technical details and impressions of the Bluetti Apex 300. 

The LiFePO₄ battery of the gadget is rated for 6,000 charge cycles while retaining at least 80% capacity. Another nice-to-have is companion app support, which further allows you to tweak the power station’s settings and monitor overall performance. 

All in all, at the $2,183 discounted price on Amazon, this deal seems like a pretty practical investment for those who want a scalable power station. Plus, Bluetti is also offering up to 46% and 44% off on its Elite 200 + 200 W solar panel combo and AC200L portable power stations via Amazon and the Bluetti online store
