    I was traveling and had no way to charge my phone. This came with enough juice to charge my phone. Bonus points for the included cord being used to to both charge a device and the charger itself

      Hi Mamu,
      Glad to hear this power bank came through when you needed it most! The dual-purpose cable is a small but mighty feature—perfect for travel when every gram and plug counts. We designed it to be simple, reliable, and ready when you are.

    I love this inexpensive battery pack. It charges quickly when plugged in and stays charged on the go. It doesn’t use much of its own charge to charge a phone. I love that it offers both a USB-C and a an old school USB port. These are great to keep in your backpack, car, or purse, in the event of an emergency or just to bring with you tailgating all day.

    Here’s a review draft you could use or adjust: ⸻ ⭐️⭐️⭐️⭐️☆ I’ve been using this portable charger for a few weeks now, and overall it’s a reliable backup power source. The biggest strength is its capacity—it can fully charge multiple devices before needing to be plugged in again. I’ve charged my phone, earbuds, and even my tablet on a single cycle without any issues, which makes it great for travel or long days out. That said, the downside is the recharge time. Once the battery is drained, it takes over 10 hours to fully recharge. This means you really need to plan ahead and leave it plugged in overnight. For someone who needs quick turnaround charging, this could be a drawback. If you value high capacity and the ability to power several devices, this charger does the job well. Just be prepared for the long recharge time .

      Hi user313463,
      Thanks for the thoughtful review! We're glad to hear it's been a reliable power source for multiple devices—perfect for travel or long days out. As for the recharge time, you're absolutely right: with a 10,000mAh capacity and 15W input, it does take time to fully recharge. Plugging it in overnight is a great way to stay ahead.
      We appreciate your insights and look forward to hearing more from you in the future!

    Good backup battery charger. Recharges to 100% from zero percent in a few hours. While charging my phone (with a 5000mAh battery) and the charger is at 5%, I noticed the charger will go to zero percent in a few seconds. Just something to be aware of.
