    What are the portable mobile power banks

    Portable power banks provide convenient, on-the-go charging for smartphones, tablets, and other electronic devices. They have become essential for people who spend time away from traditional power sources, whether traveling, commuting, or during outdoor activities. How many devices do you take with you on your travels, and do you need a power bank? At the bare minimum, you probably own a smartphone, but you might also have a combination of a smartwatch, laptop, tablet, music player, digital camera or handheld games console. What that's taught me is that capacity (mAh) really isn't everything. Their primary function is to. There are six power banks on my desk right now. On the shelves behind me are a dozen (two dozen?) more. Over the past three years, I've tested more than 55 portable battery packs for Engadget — and can attest these handy devices are only getting better.
