Lois Mackenzie usually writes about running shoes. Or how to shave minutes off a half-marathon. Today, she is talking about batteries. Specifically, the Jackery Explorer 300. It’s on sale at Amazon. $199. A drop of $60 from the usual price.
Not a bad start for May.
This thing weighs 7.5 lbs. Light. Easy to lift with its integrated handle. Inside sits 292 watt-hours of power. More than enough to keep a laptop humming or charge phones when the grid fails.
Reliability doesn’t always weigh a ton.
The outputs are versatile. Two AC outlets. A 100W USB-C PD port that actually charges modern devices quickly. Two USB-A slots. A 120W car port. The rated output sits at 300 watts, but it can handle 600 watts of surge power. That’s the key detail. You aren’t powering a house. You are powering essential gadgets. And doing so without worrying about a blown fuse.
Then there’s the battery chemistry.
LiFePO4.
Lithium Iron Phosphate. It matters because standard lithium batteries degrade fast. These ones don’t. They last for 4,000+ charge cycles. Roughly 11 years of life if you use them moderately. Solar charging is possible too, provided you buy separate compatible panels. You get the AC adapter and car cable in the box though. A solid bundle for under $200, even if the math feels lucky.
The sale price changes. The inventory vanishes. It happens often. If you see the $199 tag and you need a portable power source that won’t die in two years, you probably act fast.
But then again. Do you really need one?
Maybe. Or maybe you just like looking at the specs and imagining the worst-case scenarios where the power goes out for three days. We all have those imaginations. The deal is live right now. It likely won’t last.
