I've been backing RollingSquare for a while now and they produce some of the best things. Their commitment and communication is excellent. If I had an issue with anything they sorted it out quickly. InCharge 6 is a quality product that works very well

The previous model was defective but the customer service was very good in exchanging it.

For me, where I want connectivity between power pack and iPhone to fit in a small volume on my bike to recharge on the go (and to come out of my pocket to top up the battery pack, should the opportunity arise) this is just right, fitting neatly together in a water resistant pack. No moving pieces to get in the way: ideal
