    When you’re biking in the middle of nowhere & your electronics die out on you - it’s nice to have an Anker in your backpack for insurance.

    Great little power bank. Takes awhile to fully charge itself but you can get several charges out of it.

    I can charge my iPhone fully, twice. However, when the Anker portable charger dies, it takes a while to charge back up to 100%.

    My wife and I bought a different power bank before and within 6 months, it started swelling outside of its case. This one has been perfect.
