I try to standardize on batteries for obvious reasons. Broadly, I lead a life of AA- and D-batteries. But as of late, it seems like more and more devices use rechargeable batts that are recharged through a USB connection of some kind. I’m kinda liking this from a survivalist stanpoint.
There are plenty of chargers out there to recharge AA and D batts from various sources, I recognize that. But it’s just so much easier to order up a small folding solar panel, plug in your USB cable, and start charging your device. The things that, most notably, come to mind are cellphones (which have tremendous utility even in a world without phone signal), flashlights, small radios, and that sort of thing.
I’ve also a few devices that can use either available batteries or use built-in rechargeable-through-USB. For example, the Fenix PD35 that I picked up a while back will run off a couple CR123 batts or can be run off its rechargeable battery. Thats pretty handy.
I had a small folding Goal 0 panel that, while handy, has a rather small footprint, and when it comes to solar charging the more panel area you have the better. There is, of course, a point of diminishing return…you want a panel thats large enough to get the job done but, at the same time, you want a level of portability and compactness to make transport and storage a bit easier. Seems like a reasonable idea, yes?
Goal Zero sometimes has ‘road shows’ at CostCo and they have some very interesting stuff. I have a bunch of their daisy-chainable LED 12v loights that I highly recommend. I decided I wanted to get a little package that wouuld charge AA (and AAA) batteries, charge a phone battery pack, and could charge other USB-connectable devices. By charging AA batts that gives me a lot more use to handheld GPS, AA flashlights, radios, weaponlights, weapon sights (for the ones that run on AA or AAA), my ICOM R6, and a host of other AA-batt compatible devices.
So, off to Amazon for:
Hurricane Sandy left some folks with power, and they became very popular very quickly. I’m trying to avoid this sort of social clusterbomb.
A couple things to note… The Guide 10 battery charger has a USB port to allow you to use it to charge your USB devices. So far so good. However, it is 5v 1amp vs 5v 3amp of the Venture power bank. What this means is that while the battery charger, with a load of recharged batteries in it, will charge your phone or device…its gonna take a while.
The Venture is 5v 3amp so its gonna charge your toys a good bit faster.
Both devices can be charged from other sources, such as a wall outlet using a USB cord and plug-in. Both devices also incorporate a basic power level indicator and also have an LED flashlight feature. Handy, but shouldnt you already have a flashlight?
I drained all the batteries in the Guide to 0% and did the same with the Venture. I set up the panel in the sun, tucked the Venture or Guide behind the panel in the shade to keep it from cooking, and left it while I went to work. When I got back in the afternoon, the devices indicated a full charge. (Note: they were not charged at the same time. The panel has one USB port, so I alternated.)
The panels themselves seem fairly durable. I’d try to avoid bending or flexing them (although there are flexible panels out there). In terms of compactness, the panels, when folded up, are about an inch or so thick, and takes up a footprint slightly smaller than a sheet of paper.
You can, of course, plug whatever device you are trying to recharge directly into the panel’s USB port but then your device is subject to the vagaries of uneven charging as the sun may or may not experience some transitory cloud cover. (And, wow, my brain parses ‘vagaries’ completely different than what it means when it see it on screen. Gotta check that word twice.)
Really, the best option, it seems to me, is to use the panel to charge your storage device..batteries or power bank….and then charge your device from those. And, of course, you can charge your other devices from that power bank as well.
So..I’ll play with this stuff and see how it goes but so far it seems like an acceptable way to keep my small devices topped off when grid power just isnt in the cards.
Merciful Crom….so true, so true.
