Li-Polymer is a battery cell technology well known for some time now due to its use in cellphones. Apple has in its 2015 models of iPad Air’s, Macbook Pro’s and iPad Mini’s changed from Li-Ion batteries to Li-Polymer.
The reduction of weight in the packaging for Amped chargers is one of the essential reasons we selected this technology. In addition to this its the Energy Density that makes these battery cells so good, Li-Polymer packs three to four times the energy of a “normal cell” for the same weight “energy density”. Performance is key to the Amped chargers power output and therefore the more powerful the device the better.
