    We took this with us on a two week trip through London and Paris, and while it takes a few hours to fully charge up to full because of it's sheer capacity, it will in turn last for such a long time, which is highly necessary when traveling abroad and power sources aren't always going to be guaranteed where you're going to. I kept this in my front-body bag and it worked like a dream whenever my phone starting getting tapped out from using maps/GPS a lot. The other factor to keep in mind is that it is decently heavy, though if you have a small enough bag and you're not carrying too much else around with you it's not that big of a deal to me at least, but I have seen other reviews that also mentioned that. To me the higher capacity of the battery outweighs the minor inconvenience of *carrying something a little bit heavier than your typical tablet-sized phone.*

    I absolutely love my Energizer MAX 20,000mAh power bank! With its LCD screen, I always know exactly how much juice is left, and it charges my Samsung smartwatch and phone multiple times on a single charge. The three ports are perfect for powering all my gadgets at once—fast, reliable 15W output keeps everything running smoothly during long days out. Super sturdy build too.

    Although heavier than I expected, this battery charger has replenished my phone multiple times (about 25% per charge) before needing recharging itself.
