USB Rechargeable Batteries/Power Management?

Hey all, looking at some of these new rechargeable batteries that recharge via a micro-USB connection. Anyone have experience running these? My thought is basically this. I have a solar panel, and it's going on my trip regardless for my GPS, so to me it makes sense that id just run rechargeable batteries, and having the USB recharging option means the charger is going to weigh just a few grams (maybe a 4" cord).

But when I look around, I'm not seeing alot of options for these batteries, outside of a few very sketchy looking options on Amazon. Anyone have luck running these batteries and could recommend a brand? Specifically in the AA or AAA sizes?

Second question would be, if these are not a great option, what kind of chargers do people take with them? My backup would be a regular battery charger (as lightweight as I can find).

I realize my solar panel is a very slow charge solution, but im not trying to live in the backwoods forever, just buy that much more life for the batteries I do bring and use.

I gave up on my Goal Zero....too slow.

Now I just do backup batteries I can charge ahead of time....or from a truck, quad, side by side.


Its important to match the solar panel to the source as not all batteries will charge from some of the lower output panels.

I too gave up on solar. It’s just too unpredictable, and when it does work it’s too slow. Maybe that’s due to me being in Alaska where the sun angle is so low, but I’ve never been able to get a useful charge rate out of it.

I use USB battery packs exclusively. I have a 10 Ah (amp-hour) and 6 Ah pack, and bring one or both depending on my needs. There’s no weight penalty to me at all, because if I were using the panel it would be hooked up to one of these packs charging in an optimal, static position back at camp.

I ran a “biolite solar 10+” last year in AK and it did really well. I tried the goal zero for years and had sworn off any solar until I was with someone using the biolite and was blown away with how well it did even with overcast skies. I run an anker as a battery pack as well.

i run a couple different setups

dark energy poseidon

or

i run this charger from countycomm with a few 18650’s


the charger will charge a battery and give a charge to a device from an 18650 or other rechargeables and it doesn’t weigh much more than a cable.

olight makes a similar charger but it isn’t bidirectional.

On a side note, does anyone have a good backcountry charger for Apple Watch?
