    Recently I bought the cellularline free manta 12000mah,(fast charging).
    Using it on devices charges them extremely slow, since it is a 5v 2.1 a output. My p10 lite charger is a 5v 2a output and charges my phone 2 times more in half time. Also the power bank doesn't seem to charge my phone the amount of times it says it should. Since it's a 12000mah powebank and Huawei p10 lite has about 3000ma, shouldnt it charge like 3 times at least? Thanks

    From my understanding, your phone and charger have one form of adaptive charging similar to Qualcomm's Quick Charge (if not that specifically), which charges at higher voltages. The battery pack doesn't appear to have that feature, limiting it to slower charging speeds. If I'm mistaken, then feel free to correct me.

    As for how many times it can charge the phone, 3 charges is about what I'd expect. As the battery pack feeds your phone, it will lose voltage, which is what's needed to get the current to flow to the phone. Think of it as a bucket of water with a hose leading to an empty bucket. As the full one drains, the water level starts to equalize and the flow of water eventually stops. This difference in water level is similar to the voltage difference between the pack and the phone. As the voltage in the pack drops, it's like the water level equalizing, and it'll stop feeding current into your phone despite still having capacity in the pack.
