Hypermac 60Wh External Battery for iPad - SilverHypermac 60Wh External Battery for iPad - Silver Product Description:
Although this 60Wh battery will work with the MacBook Pro 15/17 inch, it is not recommended as the MacBook Pro 15/17 inch draws up to 85W of power. Battery physics dictate that a 60Wh battery is most efficient at providing up to 60W (1C) of power. A 60Wh battery can still provide 85W of power but at lesser efficiency, approximately only 70% of a 60Wh battery capacity will be available to the MacBook Pro 15/17 inch. The remaining battery capacity will still be available to lower power devices like the iPhone. This power limitation affects all batteries with capacities lesser than 85W and is not specific to the HyperMac. This does not affect the MacBook and MacBook Pro 13 inch which draws up to 45W, 55W and 60W power respectively, which are equal or lesser than 60W. MacBook Pro 15/17 inch users are recommended to use at least a 100Wh battery which can efficiently provide up to 100W (1C) of power. Likewise a 150Wh/222Wh battery can efficiently provide up to 150W/222W of power respectively
