Omnicharge has managed to secure funding of over US$1 million on Indiegogo for its Omni Ultimate battery-charging solution. The device offers a colossal 40,300 mAh (145 Wh) battery capacity but is considerably more portable than some of its rivals. It comes with a plethora of features to help it stand out of the small crowd of mega-chargers, including the ability to replace depleted batteries on the go.

Not too impressive when you can buy a portable, multi-purpose 185 Wh / 50,000 mAh battery bank for as low as $100.
Also this battery is rated at 500 charge cycles, which is extremely low for a product this expensive.
