    Is this an improved version of the PB2? Only, neither of my models will charge my iPhone 5c to more than 90% with the previously fully charged PB2 showing 72% on two 3500mah cells.

    Question: if I leave two 18650 batteries inside for a long time, as emergency power bank in a bag, will the batteries discharge?

    From HKJ's review...

    Measurements



    • Power consumption from usb when idle with no batteries is 9mA
    • Will charge one battery with 2A
    • Will charge two batteries with down to 1A on each (Lowest voltage will get more current)
    • Will discharge a full battery with about 0.5mA when powered.
    • Will discharge a full battery with about 0.1mA when not powered.
    • Below 0.5V the charger will report error
    • Between 0.5 and 3V the charger will charge with low current (200-300mA)
    • Above 3V the charger will use full current.
    • Will not restart charging if voltage drops.
    • Will restart charging if battery is inserted.

    It's not that bad, at 0.1ma drain it would take a 2500mah cell about 1000 days to fully discharge.

    I may think about getting one.

    The idea in itself is not new, using a charger as a powerbank.
    On the other hand, the chosen solution is very elegant

    These are excellent devices, but I would like to know if this is a new model as in my previous.

    I've been using mine for backpacking. I just like the ability to use my own cells instead of a sealed pack. The life remaining in numbers vs. random dots or bars sealed the deal.

    My iPhone 8 does something like this. Quits around 85% or so. I have to unplug it and start again and it seems to work.

    I think it's when the phone's current draw drops below a certain level and the charger cuts off.
    It's just that they stated at the top that it does a full charge on an iPhone 7 plus. So I wondered if this is a newer model that the ones I have.

    You mean that when you consume 72% of the 2 batteries, but the iPhone 5C is only charged 90%?

    Correct. It's the same with both my PB2s and both my Iphones.
    Others on here have found similar.

    Self-discharge will occur regardless of whether the battery is placed in PB2, so I suggest you take the battery out when you are not using it.

    For now, this is still an old model, and the new model will appear at the shenzhen e-cigarette exhibition on April 14th.

    Can both protected and unprotected cells be used in this item?

    No, protected won't fit. Flat top IMR only.

    I am very interested in the XTAR PB2, but actually it can not charge a small device like a mp3 player or small headlamp due to cut off charging below 290mA (HKJ Test/Review).
    Will this be improved in a newer version?

    Could it also use 18650 batteries until 3.0V? At the moment, it cuts off working at a higher voltage (3.2V) which is fine for the batteries, but there is left some power which could be used to charge devices :-)

    Thank you for any advices,
    Peter

    It fit for the unprotected 18650 battery.
