Whats inside the Powerpack.
The Fonz Powerpacks are made of high quality lithium technology; the forefront of rechargeable cell technology with superior reliability, recharging time and power to weight ratio. The PowerPack does not develop “charge memory” so you can recharge as frequently as it is convenient to do so. Lithium Ion is an environmentally sustainable technology and does not use heavy metals like mercury or cadmium found in other batteries.
