I have to admit that when I first started pursuing a Jackery to test for a review I wasn’t sure how much I really needed it. However, considering the 300 holds about 30+ phone recharges and around 4 laptop recharges (or work while charging) it was just too intriguing to not at least give it a try.
I also had another good reason. The Isle of Warlordia, sitting squarely in my backyard surrounded by a koi-filled mote had no electricity wired to it. I put a Bio-Lite solar lighting system on the island last year to light things up a little and really enjoyed the radio that is built-in. A nice little surprise with decent fidelity for a single speaker. That was my first foray into solar or stored electrical power on the island.
I have always been interested in solar generators and storage units like the Jackery since I like my gadgets. No… I LOVE my gadgets and quite frankly… a day without gadgets is a day without sunshine for me. Like a lot of us.. unless I’m engaged in some activity complete boredom sits in. So much so it makes me wonder why I’m not where my gadgets are.
As to size… I didn’t want to break the budget for us regular folk so I looked at the 300 which is a new version just above the older 280. In case you are wondering… the number is the number of watts.
From Relion Battery website:
As mentioned above, batteries are rated in watt-hours or amp-hours.
For this example, you would need a battery or bank of batteries with a capacity that adds up to more than 139 amp-hours or a means to recharge at a rate that is equal to or faster than the rate you're consuming. Click here for the link to more info.
While I could have gotten a 1000 or 1500 they are simply too large to cart around for gadget use unless you are really hardcore. They will power more items, but the footprint and weight make them more stationery instead of mobile. The 280 had my eye for quite some time until the new 300 was released with new features and better recharging such as pass-through.

Pass-through charging is, in the simplest terms, a technology built into power banks that allows a device to be connected and recharged while the power bank is plugged into a wall socket and charging itself. Click here for the link to more info.
This unit comes in at a decent $299 (US) and is cheaper if you look for specials and coupons. Unlucky for me there were no solar panels included as that is a separate item. Besides I was reviewing the powerpack itself… not the solar recharging as YouTube has a lot of videos about that topic with some claiming you can use other panels with an adapter.
All I was interested in was the concept of lugging around a battery pack to keep gadgets and me, happy. When it arrived at my doorstep I immediately opened it, found it to be around 80 percent charged, and proceeded to fully charge the device. Initial recharging is required before use or else some kind of threat involved the warranty ending up out of sorts.
It wasn’t long till I wanted to watch a movie on the island which is conveniently housed under a homemade cabana. What does this have to do with laptops? Like a lot of us.. that is what I use on the island to watch movies and, like a lot of us run into, it had little battery power left. A perfect test for the 300!
I hooked up the Jackery, turned on the appropriate plugs and the laptop showed to be charging. Nice! This is that pass-through stuff… and important stuff it is as having to wait till it charged the laptop is not what I have in mind for convenience.
So far… the laptop has performed flawlessly with movies and the sorts of stuff we do on laptops. Phone low? Plug it into the Jackery and all is right with the world. Keep texting, gaming, surfing with confidence as the Jackery powers the phone and charges it too.
