What is the Flux Portable Charger?

The Flux Portable Charger™ is a sleek power bank with a smooth material finish that comes with built-in cords for iPhone and Android. However, it doesn't stop there: you can also charge cameras, iPads, headphones, and anything with a USB, microUSB or lightning port. It is a truly universal portable charger

The Flux Charger packs 1-2 full charges (4000 mAh) and the Flux Charger Plus comes with 10,000 mAh giving you about 3-4 full charges. You can easily put it behind your phone and it will fit nicely in your pocket or purse. Pro tip: if you get a USB-A to USB-C adapter (sold separately) you can also make the Flux Charger Plus a killer USB-C portable charger for laptops or other USB-C type phones.
