Customer Questions and Answers

  • How long will it take to charge my iPhone?

    • About the same amount of time as the 5W wall charger that comes with iPhones.

    • How long does it take to fully charge the Powerbank.

      • 4000 mAh is just larger than a typical mobile phone battery. It takes about 3 hours to fully charge.

      • Does this support pass through charging? i.e. Can it charge devices when it is being charged itself?

        • Yes, the powerbank supports charging while it is plugged in and being charged itself.

        • Can I take the Megabank through TSA in carry-on luggage?

          • According to the TSA you can up to two spare batteries per customer in carry-on luggage. These powerbanks are rated < 100 watt hours which means they can be packed in checked luggage as well.

          • Does the Powerbank come with extra cables for charging my devices.

            • Not really “extra” but the powerbank comes with two built in cables – one lightning for your iPhones and the other micro-USB for most android devices. And you can always buy a nice three pack of high-quality Paracord Lightning Cables here.

            • Can the Powerbank be charged with USB?

              • Yes, the powerbank is designed to be charged via USB with any standard micro-USB cable (included) and USB wall adapter (not included).
