    @Julian Ilett​ –
    @ESTD3 As for cases,, I have found non specific cases on Amazon. Depending on your desired layout.

    Granted – Replying after two years:
    The Samsung 18650's just purchased the other day,
    have protected tips. Required for Older GPS, uses 1.
    Standard 18650 is 65mm.
    Protected 18650 is 70mm. About $15.
    From the 18650 Battery Store, Stockton GA.

    *Now isn't that interesting – 18650,,,
    18=dia mm 650=length mm.

    The mystery I'm having with the same size PB as tested
    here in video, but it's by 'LimeFuel'.

    When meter is applied to pair of black & red wires leading
    to circuit board, from battery pack,
    it appears all 8 -18650's are ganged in parallel
    showing 4.09 volts with PB display showing 95% charged.

    This is where Julian missed this voltage test in first video,
    to see if this is normal layout with 8 batteries.
    If so,, how is PB putting out 5volts plus?
    Makes me think chip sets have voltage booster regulators
    built in.

    Possibly dropping voltage boost mode in bypass.
    No idea,, brain is trying odd work arounds, making it more confusing.

    Cheers,, and by the way,, very cool detailed VIDEO,
    and USB gizmo testing devices. I'll be wanting those for my kit.

    hello everyone, I have a usb meter its fairly accurate but i want to know when i charge my phone using the usb meter shows some current and the current stays fairly stable but even if i move the phone without using it the current reading on the meter changes a lot. I wonder why is that?

    Was the power bank supposed to be off at the last few seconds of the video? as all the led's were still on pulsing a few times a second!

    I know this is probably not the right place to ask this, but i really want a good power bank case. I have 8 18650 batteries waiting to be used in a power bank, but i don't want a cheap power bank that has bad quality ic or coil whine or anything else. Can someone give me some links for tested, good power bank cases?

    This made more questions come to mind for me. It would be cool to see the pulsing of the LED's on an Oscilloscope. Also, did some instructions come with the unit and if so, did it explain why it has two charge ports? Can more that one of these be chained together for more output? I may have to get one myself to answer my own curiosity.

    +Julian Ilett Are you using a quick charge 3 wall charger?

    Is there any way to find out the quantity of lithium metal in the batteries? US restricts lithium content to 8 grams for carry-on battery packs

    Julian, I was thinking about buying one of these, but the Amazon reviews are not good, especially with unreliability. Connectors failing, substandard connecting leads, LEDs failing, or not working when new, batteries not holding enough charge, and other batteries failing to hold a charge after a few months of use. Can you please use this power bank regularly for a year, and then give us the results of your 'long term' test? It would be a 'small sample test', but would give us a fairer viewpoint than can be trusted on Amazon. Thanks.

    wow that is a really weird setup!! too bad the quick charge goes off, you cannot backup your rooter with it 😀

    Explained in very detailed… love it

    When you plugged in the charge line in, and the 2 little card lights dimmed, I thought about "back feed". I have a small powerbank that does this. I first realized it when I was going to test with a charge Doctor,, having the line plugged into both powerbank, and CD, before plugging into the recharger. I wonder why that's allowed.

  12. Avataaar/Circle Created with python_avatars Jay Herde says:

    What happens when you have an LED in the quick charge and plug a charger in the 'rearward' socket?

  13. Avataaar/Circle Created with python_avatars Andy Lee Robinson says:

    Still a useful device in spite of these flaws, but as long as they are disclosed then we can work around them.
    I hope they'll try to update the architecture so it will work seamlessly as expected without these surprises.
    Julian, please also post links in the description to where we can buy those usb leds and testers!

    Hi Julian, could you measure, with your USB Power Monitors, the energy that can be delivered to devices? Suggest just one USB output through to a 1 Amp load for a start. Then, when it's fully discharged, use the same USB Power Monitor to measure the energy required to fully charge it.

  15. Avataaar/Circle Created with python_avatars Brian Cockburn says:

    Hi Julian, perhaps we could see what's going on with the LED flashing by looking at the voltage(s) with an oscilloscope?
