Monster Watts, an innovator of external battery chargers for Apple and Samsung phones, is clearing out the much-acclaimed iPhone 4S Hybrid Solar Battery Case to make room for the iPhone 5 model arriving in December.

Innovative Design

After a few months of use, all mobile phone batteries run out of power sooner. Battery cases and even solar powered chargers to extend the battery life are not a new idea, but the Monster Watts model is still the only one that keeps Apple's design integrity with high functionality.

The Monster Watts Hybrid Solar Battery Case has been praised as the best available because it combines the highest efficiency solar panel charger with the most powerful rechargeable battery in a thin protective case made of tough ABS material. It comes in black or white, and can even be personalized with replaceable color bumpers.

Whether outdoors playing, or indoors working, away from electrical outlets, users can relax knowing that with the extra 150% battery life and ambient sunlight – their iPhone 4S will not run out of power, all day and night.

The hybrid charging design automatically charges the 2400 mAh rechargeable battery whenever it's under sunlight, but just in case, it can also be charged from any PC or standard phone charger via the built-in USB port. Of course, all buttons and ports are still fully accessible.

Inventory Clearance Promotion

The suggested retail price of the Hybrid Solar Battery Case 4 Bumpers Package is $128, but in cooperation with www.Vivealive.net, it can be purchased for $64 and comes with a total of 4 color bumpers. This is limited to inventory in stock.
