    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Initially, the power bank was purchased due to an immediate need for portable charging power (what I needed, not necessarily what I wanted). The performance from the power bank hasn't 'blown my expectations out of the water' per se, though, I am pleased with my purchase thus far, leaving me without discrepancy nor complaint.

    I have an old VW van which does not have a working cigarette lighter, so I have no way of charging up my devices when I am driving it. This enables me to keep my devices charged while I'm out driving my old VW. And it's charge lasts much longer than I anticipated. No regrets.

    Purchased this for "just in case" power needs during our recent family vacation trip and was a great buy! Perfect for the times getting through the airport and to and from destinations when that little extra bit of juice is needed!

    I really enjoy having this battery pack. I am constantly on my phone with work. At times I don’t have access to charge inside the office. This thing comes in so handy to get my phone back up to full charge. Worth every penny in my opinion.
