    So fun to learn from here ๐ŸŽ‰

    Quite a poor review, there is no section with actual performance numbers.

    Kommon sense review from a kommon sense guy… Thanx!

    hi, am interested but not knowledgeable at all on this topic do you know if the bigblue would allow me to charge a Xiaomi Mi 50w Power Bank 20000mAh Lithium-Ion (Li-Ion)? Thanks in advance ๐Ÿ™‚

    Survival Frog 4 panel?

  6. @christopher5487 on January 16, 2025 at 8:06 pm

    Thanks for review

  7. @cursedfox4942 on January 16, 2025 at 8:09 pm

    So everything is useless but the big blue charger

  8. @mauricemotoman3305 on January 16, 2025 at 8:12 pm

    Can both the powerbank solar panel and the solar charger panel charge the powerbank at the same time? Because if so i can buy both

  9. @jimmyhollywood on January 16, 2025 at 8:14 pm

    How can connet 4-panel to iPhone 13 Pro

    Thank you

  11. @ruthlessgray on January 16, 2025 at 8:14 pm

    Very useful video. Helped me make a decision regarding portable solar.

  12. @taniabrown8173 on January 16, 2025 at 8:15 pm

    Loved your video, however, there were a lot of reviews on Amazon about Big Blue that were not favorable at all, many said it did not work well or at all even in direct sunlight. This is so confusing now cause your video really had me thinking about Big Blue and a charging bank…not sure now.

  13. @Elkatook666 on January 16, 2025 at 8:16 pm

    just bought a new solar panel for my dad for christmas , it has usb-c out … its this one –

    ELECAENTA 30W ETFE Foldable Solar Charger
    i realise the video is a year old and this is probably out of date by now as a problem!!

  14. @missyoubeth on January 16, 2025 at 8:16 pm

    Great video thanks.

  15. @chiccaikoh3944 on January 16, 2025 at 8:17 pm

    Can you charge a powerbank using a solar panel?

  16. @simonthebroken9691 on January 16, 2025 at 8:20 pm

    Thank you

  17. @bdbarnes on January 16, 2025 at 8:20 pm

    The usb adapter usage, can be used in the waterproof satchel side.

  18. @Mania_XDLOL on January 16, 2025 at 8:22 pm

    Do we still get electricity bills if we use the solar power banks?

  19. @kelakinyele5886 on January 16, 2025 at 8:22 pm

    Thank you so much. I already have the solar power bank, however I need the fast charge, so itโ€™s the stand alone for me I can charge my power bank as well directly from it also.๐Ÿ˜…

  20. @somenewuser on January 16, 2025 at 8:23 pm

    After watching this video I am going to get myself cleaned up in my weather simulation chamber

  21. @isegrim1978 on January 16, 2025 at 8:24 pm

    Planing a 2 week canoe camping trip, so I am looking into folding solar panels.
    Weight is luckily only a factor for travel from and to the start/endpoint.
    I think I will pick either my 20k mah or two 10k mah Anker power Banks, so the power Bank can sit all day, connected to the panel and charge.
    For a 1 week trip I would most likely only pick an extra 20 k mah powerbank and not take the solar panel.

  22. @larry3476 on January 16, 2025 at 8:24 pm

    Thanks,Big blue for me

  23. @whistleblower66 on January 16, 2025 at 8:25 pm

    Good thanks but you talk too fast ๐Ÿ˜–

  24. @snakespeare8252 on January 16, 2025 at 8:26 pm

    Is it safe to plug a 40W solar panel into a power bank as demonstrated in this video without the need for a solar meter/controller?

  25. @jarleoudalstol2275 on January 16, 2025 at 8:27 pm

    Hi I just wanted to mention that the 60W foldable solar panel from Flexsolar has a USB type C port on it.

  26. @PRAISE.53 on January 16, 2025 at 8:28 pm

    Power bank. Kept me safe through a hurricane

  27. @allsin03 on January 16, 2025 at 8:29 pm

    Itโ€™s probably best to just get Boffum ๐Ÿ˜…

  28. @davidvasquez08 on January 16, 2025 at 8:30 pm

    2:11 I have a bank similar to this, though I have no idea if the solar panels can be detached
    Can a solar bank have 8 panels, can it recharge even quicker?

  29. @engineerncook6138 on January 16, 2025 at 8:30 pm

    I’m looking for a solution to charge 1 or 2 phones during an extended power outage 1-4 weeks in a location that is often overcast. Portable solar panels make much more sense for my use case. I have always expected that the solar panel on the solar power banks is just to small to be practical .

  30. @BuildLancer on January 16, 2025 at 8:34 pm

    i think ill go with the solar charger since i got 2 10000mph banks already

  31. @MICROKNIGHT3000 on January 16, 2025 at 8:35 pm

    Do you have recommendation for a 20k power bank in all black colour no accent colour that also has solar panels? Doesnt have to be many panels as its just for backup without dolar charger.

  32. @basilbruder9210 on January 16, 2025 at 8:36 pm

    what about solar panels heating up. im here in the amazon rainforest. i try to charge my devices in the early morning sun. but at 8 am it already feels like midday sun(almost). so the panel gets pretty hot. ehen i put my hand on it i need to take it off after couple of second because of burning sensation. i also try to not angle it directly at the sun.

  33. @lady_phoenix9946 on January 16, 2025 at 8:36 pm

    Thanks, you made it easy for me as I knew nothing about solar panels. I bought the big blue one ๐Ÿ‘๐Ÿป

  34. @rap36case on January 16, 2025 at 8:37 pm

    Get a propane camp stove, lantern, and a dual fuel generator for the big stuff.

  35. @lil_Marie_Red on January 16, 2025 at 8:39 pm

    Just shade any devises you are charging.

    *****Funny, most these "REVIEWS".. they never test a fully charged unit.. how many times it can charge an iPhone XR. ******Banks are good for camping.. but not backpacking.. just too heavy.
    I have three (3) "BLAVOR PN-W12 Pro" Solar power pack battery with solar….. instead of 1 solar panel, it has 4. If drained, it takes 4 days to charge up by solar. The Panels are good if camping and keeps it topped up. The Battery is "20,000 mAh" but it can’t fully charge my iPhone XR only 3/4. My iPhone has 2,942 mAH battery…. so….. feels like really a heavy 2,000 mAh. That is the Bad (Posted negative review on Amazon, $45) …the company sent me two more free… but they both had the same results. The GOOD is the very bright LED lights last a LONG LONG LONG time. Like 10+ hours on full charge.. that is impressive. So BAD, in charging a smart phone, GREAT for camping and bright BRIGHT LED light… and a compass also.

    This one does not have wireless charging… USB 2.0 and 3.1 charging (I checked the output, only 2.1 Amps at 5 V each. I have older type that have wireless charging and 5 (five) panels… still "13,000 mAh battery" but really, 2,000. IT could be the efficiency of charging the battery to 5V 2.1 Amp is very very very poor and the battery is really 20,000…. but I doubt it.

  38. @RCSky7711 on January 16, 2025 at 8:41 pm

    How many watt solar panel do i need to fast charge one or two phones? I have a bank and the solar is a joke, i just want the bare minimum i need for an emergency

  39. @mynamesjeffhardly on January 16, 2025 at 8:45 pm

    Can you use the portable solar panels along with the solar charging panels on the portable battery? Will they charge faster together?

  40. @samranch4519 on January 16, 2025 at 8:48 pm

    Nice touch leaving in the blooper. makes the vid more enjoyable as well as informative.
    Thanks

    Can I put it on my windshield?

  43. @SilverPony44 on January 16, 2025 at 8:49 pm

    You said it man itโ€™s all about charge speeds if you have a few power banks you can charge several and have a full on system

  44. @suezbell1 on January 16, 2025 at 8:51 pm

    What is needed is a really wide brimmed hat w/solar panels and the holes for cord connections could be inside the hat with waterproofing in between — or would that be a fire hazard?

  45. @drigg619 on January 16, 2025 at 8:53 pm

    Very Helpful information! Thank you!

  46. @dduncan221 on January 16, 2025 at 8:55 pm

    Great Video on it all it helps educate me on what is best for me to purchase. Thanks for taking the time to make and post.

  47. @powoxi on January 16, 2025 at 8:56 pm

    It’s decently sleek. The craftsmanship and the little details are pretty solid.

  48. @wethan23 on January 16, 2025 at 8:57 pm

    Love your state of the art weather simulation chamber lmao

  49. @0nyxghost on January 16, 2025 at 8:57 pm

    Most solar battery banks charge at 200 ma @ 5 volts or 1 watt. A 20,000 mah battery would take 100 hours of perfect daylight to charge.

    I liked when u asked but 1:51 did it for a comment. Excellent vid love the final comparison
