    is it possible to charge a 12volt battery with out a charge controller,
    only for a short time? I tried this on a old dead battery, will not charge.

  2. Backyardsoul says:

    when installing the volt meters, do they require a shunt like the amp
    meters do?? If so how do you determine what size shunt to use on the volt
    meters? Thanks…

    Can I connect both my 12 V gauge meter and Amp meter on the same 12v
    connections ?

    Man !Turn that rude shit off.

    The 7 amp regulators under $30.00, from harbor freight will work.

    Dude. I have a headache. Can you please move the camera slowly to show your
    panels? This is very informative once I take a few asprin.

    Nice

    very good

    Thank you – very informative.

    I have a 5 watt panel….what volt or charge controller and inverter do i
    need?

  12. Red Ferret says:

    OK, just done a further test, and we were right to be cautious about the
    claims. Whatever it is – and we’re going to open it up to take a look at
    the batteries soon – it’s definitely not a 20000mAh charger.

    I’ve just charged up my phone from 21% charge to 100% charge, and it took
    around 3.5 hours to do, and at the end there’s two out of the four lights
    still lit on the indicator. Which suggests that, unless the indicator is
    faulty, this is something like a 5000mAh pack or 6000 at most. Shabby work!

    Sorry folks.

    I believe a ton of these ‘cheap/small’ chargers are phonies. Although they
    don’t have to be. There are inline meters available to to some of the
    testing and as you did, one could pop it open. Thankfully you discovered
    the junkiness of this one. 

  14. Edwyn Rosa says:

    hey red ..can you piggyback the chargers to each other ??

  15. Heather Keeton says:

    I already knew it wasn’t what it claimed. But I only need it to charge my
    DSI XL when camping. So How long does the device take to charge fully in
    the sun and how long did it take to charge your tablet in the video….

  16. James jimjimjim says:

    Would you be able to do a test when the device is fully charged and you
    charge a phone or a tablet with a known mAh rating and see how many LEDs
    light up on the unit after a full charge to gauge how it performed. It
    would also be worth knowing how fast things charge as I have bought cheap
    chargers that claim to be 2A when in fact they really aren’t!

    hi, does it charge an ipad air if you got one to test it on.? i ordered
    mine and its a 16000mah power pack and it’s on way. just wanted to know if
    it does.?

  18. Haaris Mahmood says:

    So what’s the actual Mah

  19. Daryll Flaro says:

    Is solar the only way of charging the power bank back up?

  20. Sean O says:

    Where did you buy it from please ?

  21. Tom Grant says:

    Yeah 20 Amps for an hour at…. 5v? That’s a lot of power. I’m not sure
    what a decent sized Lithium battery is capable of nowadays but I do know
    that that sized PV would take AGES to charge it. It’d be like 3 weeks worth
    full days of direct sunlight.

  22. Roger J says:

    I think it would have helped your presentation if you informed us if it was
    successful in charging the tablet, and how long it took to do so. Without
    that information it’s not really very enlightening!

  23. ABMNS PRODUCTION says:

    Nice product :)

  24. Red Ferret says:

    Low cost solar power bank offers 20,000mAh, enough to charge your phone up
    10 times…we’re impressed…
