    A real life saver. The only issues are that the charging cable is too short and it doesn’t last as long as it should

    This product is useless. It loses it's own charge after partially charging one cell phone, let alone any additional phones. I would not recommend it to anyone.

      Thank you for your feedback! We appreciate your insight. The charging capacity of a power bank depends on its battery size and output efficiency. If you're looking for a model that can charge your phone multiple times before needing a recharge, we recommend considering a higher-capacity power bank, such as our 30,000mAh models. We’re glad to hear that the power bank is performing as expected. If you need recommendations for a larger model, feel free to reach out! Energizer Power Bank Service Team

    Powerbank drains within minutes and dies before even my iPhone 12 Pro Max reaches 90% battery. Also powerbank heats up very badly and can’t carry it in pocket while charging the device.
