MAXOAK EB40 300W Portable Power Station

Maxoak, being a trustworthy brand has brought out some of the best and affordable battery units including a massive 1000W portable solar MPPT battery bank that we had featured a couple of months ago. They have another cool product for those who are looking for a lower end yet powerful portable power storage device and it is none other than EB40, a 300W portable power bank. You might be wondering why you need this. You need this because it can charge almost any portable electronics not once but multiple times flawlessly. This feature will be terribly useful while you travel, especially by road. Apart from that, EB40 battery bank helps you while you camp somewhere or hike a mountain for a day or two. Just to give you an example, this power bank could charge your smartphone for about 30 times in a single charge. It is ridiculously high, isn’t it?

It has AC ports, USB C support, regular USB ports, car cigarette, and a 12V DC output port. With an AC port, you can recharge your laptop as well. The power rating is 400wh which is equivalent to running an 80W device for four hours straight. Unlike a normal power bank, this portable power station could recharge your drone, camera and can run portable fans, fridges etc. Costing at around $350, this power station is a go-to if you are a frequent adventure seeker.
