Do Portable Solar Power Chargers Really Work?

Cool vids. Subscribed.

ok

Half way through I had to sub.

In iraq , i have 10 watt portable solar panel , it charges my phone in like 5 hours , in midday mid summer.

You can increse the speed of photon's with magnification so it is posible to get them to work inside!

Ive found these are always best for a power bank and nothing more. Thats why I only use a 15 watt one. Its smaller and powers up small power banks with ease.

Received my Nekteck panel today. Are black spots on the panel normal? Or should I return it?

I wonder if your powerbank also was in the sun, can slow down the charging time because it get fast hot. the powerbank should be in the shadow

Putting power bank under sun will kill its capacity 😅

A suggestion - when you go thru the results along with numbers and all, you may want to consider showing the collected data in a simple table and/or graph while narrating over it for a good number of seconds. All the best to your channel!

Glad this isn't an AI generated video

Hahaha, I like the comedy too

Hi what portable solar do you need for fridge heater lamp.

1 minute video took 6 for this boomer. Pls pls sfu and get to the point!!!!

Solar panel are good investment specially for hickers but you should test it many times and buy from a store that has after sale service and fellow om good company so you get the best deal don't look for cheap prices you will regret that choice after spending a week without electricity in the middle of nowhere. My solar panel is not capable of hot sun so the sun damage it in a hot day so i lose it in a moment which i needed it, it was from i mars company for solar panels and its cost me more that hundred dollars

Heck yeah they work!!
I have several.

Love your T-Shirt and Posters…

Think I am interested I buying a couple of the big blue panels.

You got me! I subscribed!! Love your reviews with a bit of humor!!!

I love the big blue 28w, but it can't push all 28w through any of one of its usb ports. It has to use multiple ports at once otherwise its wasting some of the 28watts its producing. I wish it had a 15v solar power output like the allpower 100w portable panels have. The allpower panels are the same size as the big blue 28w panels, so they fold down to the same size. Its just about 3 times thicker when folded since it has about 3 times more panels than the big blue 28w has.

thank you for your time. I subbed

Thumbs up for Spaceballs!

Peace.. Shalom.. Salam.. Namaste and Thank You for All your efforts to support Solar Power 🙏🏻 😊 🌈 ✌ 🌷 ☮ ❤

Yeah your battery bank definitely isn't 30,000 mah, assuming your solar panels were in peak conditions producing 28 watts at 16 volts the entire time it was outside, in 11.5 hours it would've only outputted 20,000 mah assuming 100% efficiency. Usually the safe bet when buying power banks off of amazon is to at least halve their power claims.

Same model but without the useful meter, working well enough in London to put the chargers away, it even gets something when it's a bit cloudy, good winters days as well. Surprised by "the yield" to be honest.

So, amperage range (0.7 , 2.1)(cloudy , sunny). What was the panel's claimed amperage?

This one and it's little brother 14w are now on my Amazon list!
Thank you for the great info as always man!

Great information!!! Great t-shirt too!

I have an Anker 21 watt foldable solar panel that has a pouch that you can put battery bank or device in to protect from direct sunlight or rain. I typically use it to charge a 10,000 mAh battery bank completely in a day. This allows me to fully charge phone(s) and/or tablet while camping or during a power outage. Anker in my experience is a quality brand of a variety of products. Cheers
