Do Portable Solar Power Chargers Really Work? 

Funny you say that. I almost got that very charger instead of this one, but I wanted the extra wattage for the test. I agree Anker usually makes good stuff. Thanks for sharing my friend.

@@RandoTechInfo In Washington State,even though its cloudy at the beach you can still get a sun burn,would they work then?

@@galvinstanley3235 Yes, but hard to say how well.

Has it held up with use? Do you put it on the back of your backpack if you're hiking? I heard most of these things die or break in a year with heavy use, so most backpackers just carry a bank. If you're away from an outlet for 6+ days then the solar might be more useful.

@@-whackd Mine is @5 years old, but 1) I take care of my gear 2) I only use it a week or two per year. No drops or smashes. Carried on outside of backpack and lashed in place. Functioning as original.

Glad you liked it and thanks for always coming back!

Thanks for sharing!

Indeed thanks. The perfomance cloudy days is the most imortant to know for the winter part of the year!

Thanks. That is helpful. Are you able to use it from inside.

@@utubemouse No, I use it externally, I have access to a sunny spot.

The 28watts cant be pushed through a single port anyways. The USB ports arent capable of the full 28 watts. The only way you could get even 25 watts is to use 2 or 3 ports at once. It loses a few watts just to the electronics in the charge controller too.

I don't think that panel has 28W, one single side has 5 usually, so it's 20W in full sun, perpendicular with the sun all the time

He said that panels outputted 10watts in direct sunlight and charged the bank in about 11.5 hrs, considering the age of the powerbank and heat etc loss, 115 whs of total input might have charged a 95-100wh capacit. Sounds about right to fill a claimed 111wh powerbank.

Thanks Ed. Appreciate that!

That might be a future video idea. 🤔

@@RandoTechInfo Led 1.5 watt light !

It served me well!

Thank YOU!

What's your fav?

@@RandoTechInfo , to be honest, they're all good. I have several generic panels that I found on Craigslist for cheap.

It would be a good first step.

Interesting. 🤔

Thank you!

damn that sucks

Good information. Thank you!

@@RandoTechInfo So after testing it looks like the allpower 100w averages almost 5 times the power output of the big blue 28w, BUT its limited by the electronics to 80w. So in low sun it performs almost 5 times better, but in ideal conditions only 3 times better. My cheap power station cant safely accept more than 80w input for long anyways though, so it works for me. Its still 100w of panels, so itll collect more than a set of 80w panels, its just limited to 80w output even if you are collecting the full 100w at the perfect angle. The bigblue28w loses a few watts to electronics too, but not as much. Both are fantastic for what they are made for. Both exceptionally lightweight for their output. The anker 21w is another good one. Its about 100grams lighter than the bigblue 28w too. For backpacking with just 1 cellphone id go for the anker or big blue, but for family camping or a "bug out bag" id opt for the allpower 100w. I can even jumpstart my car with the allpower panels so i keep them in my car.

@@alexcrowder1673 Haven't tested anything 100 Watt yet. Perhaps I should. 🤔

@@RandoTechInfo Definitely! It's a bummer the price just shot up. They were 60 dollars cheaper on prime day than they are now ($140 vs $200). Also, make sure you have something that can take a 15-18v dc solar input because usb becomes very impractical for measuring power output on the bigger panels. Youll probably need a pretty substantial power station too. Depending on the model, probably 500wh or larger to be able to take the full charge speeds the allpower panels can output. A lot of 250wh power stations for example are limited to roughly 60 watt charge speeds anyways. So it may look like you are getting less power output than you are if your power station cant handle the input. it's basically getting throttled to protect the power station. Anyways hope that helps! Xdragon 70w are a nice middleground too that use the same high efficiency type of panels as the bigblue and the allpower. Much like the other two models, they are also very lightweight for their power output.

@@alexcrowder1673Thanks for the information! I'm probably done with solar for this season and I usually drop these videos at the start of summer, but I have the idea in my vault for next year.

Thank you. Appreciate that.

Thanks. Appreciate it!

What do you mean by "black spots"?

Thank you!

Appreciate that!

Nice. Thanks for sharing!

Thank you for your service. God bless you.

You understand that not everyone is an American?. You think someone saying they are in ​Iraq can only mean they are an American soldier? 🤔@@lanagammage9074

Oh jeez. I'm not sure but I'm pretty sure you need more than 28 Watts.

You don't use portable solar for fridges, because fridges are stationary.

@@-whackd Thank you

Thanks!

Thanks!

💀🇮🇱💀

Come back and let us know what you think.

@@RandoTechInfo I will, was just discussing them with my best friend and the 4 panel power banks yesterday evening looking into the FEELLE 26800 foldable power bank.

"Just test your stuff before you get in the woods." Good advice. 👍 And thanks for sharing.

@@RandoTechInfo And thank you for the video.

Or is it? 🤔😏🤫

Thanks for letting me know. I try to check my comments daily but sometimes some get through the net. Thanks also for reporting it.
