    Superior Quality

    The best portable charger I’ve ever used. Lasts for multiple charges. The only downside is you can’t use it while charging it (creates the need for multiple outlets), and it’s a bit heavy and bulky. Minor inconvenience for the superior quality of this product.

    Large and heavy for a purse, but other than that it is good. Takes a long time to fully charge it. Charges phone in decent time.
