    This is an excellent choice for a remote power backup for devices. Slim and not a big block, so it fits nicely in luggage when traveling and looks good enough to stay on a desk in your home office as well.

    The charger seems and feels premium quality. The charging speed is decent, and the among of charge it holds is decent too. Bottom line the charging pack is worth the price tag.

    Misleading Marketing

    |

    Posted . Owned for 5 months when reviewed.
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The advertisement on this device is so misleading. A consumer reads “for smartphones”, but it is not compatible with all smartphones, especially the new ones. I was willing to spend more at the time if it worked with the iPhone 12 Pro. I’m upset with the marketing. This product works great if all you need is 10W. I give myself one star for not asking for an associate to make sure it could handle my iPhone 12 Pro which needs 20w. At first it didn’t work on my devices, but then I learned my wall plug was defective and not giving a proper charge. Once the connection was better it works great on my old android I use simply for the radio feature. It only works on less intense devices such as J-lab ear buds and old android devices. Read the fine print on these portable batteries. It was too late for a return, plus just the hassle of returning items. So frustrating, but it does work if the right specification. Learn from my mistake, and be careful with these terribly misleading marketing schemes.

    I purchased this as a charger for my Android while flying. It sits nicely in my purse and plugs into my phone while using it. It charges my phone and my tablet at the same time, quickly.
