    MyCharge Adventure Charger

    I travel all over the world and I need to stay charged to reach friends, family and to conduct work projects. This charger, that I’m using as we speak, keeps me from having to worry about that happening as I don’t always have an adapter to use in foreign countries. You could argue it’s a little bulky but it isn’t for sitting on a desk or sliding in a carry-on bag. To be fair, if you’re like me and have cargo pockets in all your pants, it fits great on the go as well. Lastly, it’s a good value and that’s something I appreciate as I don’t like to carelessly throw my money away.

    Bought this to carry in my purse. You have to get a good cube for faster charging, otherwise it takes forever to fully charge (I used my laptop charger). Recently traveled to Mexico (with stops) and really took advantage of it. Kept all my electronics charged at the beach and still had battery life left after the weekend.

    Best charger by far hands down! Spent 5 days in the mountains with no electricity. Powered our devices with power to spare. It still still had more power to charge after coming down out of the mountains. I highly recommend this product.

    Car camping must have

    Went car camping and decided to buy this to avoid the stress of having to charge phones in the car. It was a short trip, 3 days, but I had plenty of charge to keep my phone and watch going. It is a little heavy but not so heavy that it would stop you from throwing it in a backpack, if needed. I was surprised how quickly it charged up my devices and like the fact that I could leave it in damp conditions without worrying. Game changer for me.

    I genuinely love this thing. It has come in clutch so many times. It is on the heavier side but it can go for months without needing to charge and it still charges my whole family's phones in one go.

    Great charger. Charges my devices and my phone, super fast and its very very strong resistance to dust and heat The only con is that its bulky and long so it’s much more difficult to carry in pockets and sticks out as a result.
