I've featured a lot of power stations here over the past few years, but this is the best deal I've ever come across.

Blackview, a name you might have come across if you're a fan of ruggedized Android smartphones, has come out with a power station -- the Oscal PowerMax 700.

Also: I found the Goldilocks of portable power stations (and it's currently on sale)

And while this has a recommended price tag of $599, if you order before midnight PDT on May 31, you can pick up this amazing new power station for only $234!

The Oscal PowerMax 700 is a mid-range power station. At 16.3 pounds, it straddles between ultra-portable units and those that definitely need to be in the back of a truck.

The 666Wh of battery power is capable of charging up to a dozen devices simultaneously, via an array of AC sockets, USB sockets, 12V car and DC outlet, and even a wireless charger that sits on top underneath the handle.

But how much power is 666Wh? Putting it into terms that are easier to comprehend, that's enough to run a 40W mini fridge for 12.6 hours, a 25W lamp for 30 hours, or a 40W CPAP machine for 14 hours. It's also enough to charge a smartphone around 40 to 50 times.

On the flip side, the Oscal PowerMax 700 can be charged in one of four different ways -- 150W solar panels (4.5 hours), AC wall outlet (3 hours), 12 car outlet (4.5 hours), and USB-C (10 hours).

It's perfect for a day or two off-grid without needing a recharge. If you need more out of it, you'll need to connect it to a wall outlet, a car outlet, or bring with you a solar panel.

On the safety front -- because 666Wh is a lot of power should something go wrong -- the Oscal PowerMax 700 packs all the protections you'd expect in a power station: overcurrent, short circuit, overcharge and overdischarge, overvoltage, and thermal protections.

On the top is a super comfortable carry handle, which is a must-have if you're going to be moving a 16-pound power station around.

On the front is a clear, easy-to-read LCD panel that shows you everything you need to know about the Oscal PowerMax 700. There's also a directional light that has four settings: low, high, slow flash, and SOS.

For $599, the Oscal PowerMax 700 is a decent power station that's perfect for those who want portable power but not much of it. It offers a lot of flexibility in terms of charging and powering devices, is robust and well-made, and is intuitive to use. I've pushed this power station to its limits and beyond, and it's performed flawlessly. 

Also: Why you need a batteryless jump starter (and how it works)

For $234, it's an absolute steal, but if you want it at this very low price, you'll have to hurry because the offer ends at midnight PDT on May 31.
