    Did this video eventually cover the cost of that power bank? 🤔

    Maybe the solution with these things is to find a mate who reads Chinese, and have them decipher the instructions.

    It's frustrating that I could see you putting it in the wrong way round and that me shouting at the screen made no difference.

    I don't have the capsity to compresend that. At least not in a wireless manner.

    $21.00 is expensive? Love your videos!! May The Revers..Force Be with You. Bear (wire) with me, I am Bi Polar.. Bare.
    Not really. I am Welsh. And English. And Scot. And Irish. And American. I pretty much hate myself.

  8. Avataaar/Circle Created with python_avatars jlucasound says:

    SMOKE ON THE METER! Wha Wha Wha..Wha WhaWhaWha etc. You said it was fairly expensive.
    Why would you do that? Are batteries not clearly labeled on the other side of the pond?

    I will always choose to go up against the "Wall of Science (Firesign)" rather than having a "Momentary Lapse of Reas…Polarity". Julian is English. Pink Floyd is English. I am English. In the USA. Can't speak for Firesign member's origin but they are USA.

    I'm glad other people do this too. At least you have a nice flashy-onie-offie thingy.

    It would seem that an 18650 bank without reverse polarity checks is not that good when they often have no indication on the battery. It was also noted below; the springs on both ends only lends itself to duping people. Poor design?

  12. Avataaar/Circle Created with python_avatars Ross Anderson says:

    The spring is always negative.
