      Hi CeliaRomero,
      Thanks for your review! We're glad to hear the charger is serving its purpose as a backup. If you're considering something smaller, we do offer compact models with lower capacity that might suit your needs better—especially for lighter daily use or travel.
      Feel free to explore our range anytime to find the perfect fit!

      Hi Connie,
      We’re sorry the charging experience didn’t meet your expectations. A full charge for a 10,000mAh power bank can take several hours depending on the power adapter used. For faster results, we recommend using a USB-C PD (Power Delivery) charger with at least 18W output. If the battery only reached halfway after 5 hours, it may indicate a performance issue.
      Please visit https://support.energizerpowerpacks.com/ so we can help troubleshoot or arrange a replacement if needed.

    The battery drained way too quickly. I plugged in my iPhone X2 for a charge, and soon after, it was completely dead.

      Hi QuiT,
      We’re sorry to hear the battery didn’t perform as expected. A fully charged 10,000mAh power bank should provide multiple charges for an iPhone X, so if it drained quickly or didn’t deliver power properly, the unit may be defective.
      Please visit our support page at https://support.energizerpowerpacks.com/ so we can help troubleshoot or arrange a replacement if needed.

    It’s a bit heavy for a backpacking trip but at the same it’s perfect for that purpose.
