Best Ultralight Solar Charger for Backpacking Adventures

Getting a solar charger has been on your to-do list for months…

Look, you never thought you’d find the time but here you are and now you can see for yourself which is the best ultralight solar charger for backpacking…

Maybe you’ve put it off, but thoughts of your last trip bring back memories of everyone haggling over 2 USB ports because you all had to share the same solar charger for phones and tablets?

Not having a solar charger still bothers you…

The trip was great – but still, it was a drag because after about the second day the hi-capacity battery (100000mAh) on a charger that looked like it had solar panels for a house was so drained that it never fully charged for the rest of the backpacking adventure.

The charge pretty much stayed in the yellow zone all the time, and that’s even when the solar panels were in direct sunlight for 10-12 straight hours each day.

Except for the first couple of days, everyone barely used their phones to preserve battery life for emergencies or evening calls and updates.

Nowadays with all the electronics people carry this is a pretty common backpacking story.

Ya, cellphone and tablet battery life just doesn’t last as long as manufacturers say…

And unless you plan for extra power or your trip includes an RV with a solar generator, on the trail, you’ll only have a few hours during breaks for music, gaming, texting, taking pictures, and surfing the Internet.

Man, does that suck, especially when personal solar chargers for backpacks are cheap…

Anker 21W Dual USB Solar Charger Review

Backpacking is your favorite pastime…

But backpacking is your favorite pastime, and you need your own solar charger before the next trip.

Hmm, which one will it be because there seem to be about a million portable solar chargers to choose from?

And if there’s anything you’ve learned about backpacking, it’s to travel as lite as possible so you want an ultralight charger.

That said, you’d love one of those big-bad solar chargers with a large capacity battery and 4 panels that are chained together for fast charging. You know, like the ones you saw on Amazon the last time you checked.

But the high-capacity ones probably feel like they weigh as much as a Tesla power cell battery after 8 hours of lugging it strapped to your back. No way, your shoulders are sore just thinking about it.

Not to mention how your back will ache like you’ve been chopping wood with a dull ax.

Look, imagine having your own ultralight charger carefully attached and positioned directly to the center of your backpack, right below the flap.

And all day long it’s facing upward at the sunlight sucking in the rays and charging your stuff.

That’s right, all the power you need and no more keeping your cellphone turned off to preserve the battery life.

Take all the photos you want, listen to all your playlists or play your favorite games without worrying…

Lightweight solar charger…

Plus because your solar charger is ultralight, there’s no backache ache and shoulder blisters from an over-weighted backpack.

Hey, every extra ounce of food, water, clothes, and safety gear adds up, especially when hiking over miles of rugged terrain; a charger with a big-ass battery is a definite no-no.

Plus, powering the campsite is not the plan, all you want is enough power to keep your cellphone and tablet charged for the next day…

You’re not trying to be a selfish butt-head, but shouldn’t everyone take care of their own gear?

Nah, you’re a team player – maybe you’ll order more than one so everyone’s electric devices aren’t plugged into your charger.

Anyways, it seems there’s always someone who forgets something on every trip. which is why having extra toilet paper always comes in handy…

Ya, maybe you’ll order more than one and keep your power all to yourself…
