BatteryBox says it will double your MacBook Air's battery life

Portable batteries and battery life extenders are nothing new these days. Charge the box, plug it into your laptop, and you have extra battery life. It seems like a fairly simple concept, but some ways can be more efficient than others.

Gbatteries is claiming increased efficiency with its BatteryBox portable battery. On the surface it looks like any other portable battery, but the company states that it’s insides are what sets it apart from the competition. Instead of simply supplying power to your MacBook’s battery, Battery Box will power it via its own internal battery, which will decrease the rate at which your system’s battery degrades, Gbatteries claims. On top of that, Battery Box comes with the company’s own batteryOS power management system, which manages power much more efficiently when compared with non-batteryOS assisted lithium-ion rechargeable batteries.

Gbatteries makes a case for batteryOS by claiming that it “is designed to dynamically manage energy inside of a li-ion battery pack during charging, idling, and discharging of the pack,” according to DigitalTrends. Standard batteries drain power via a steady stream, which the company claims is less efficient and does not make use of all of a battery’s internal active materials.

Gbatteries says that with batteryOS, “any OEM li-ion battery to gain the ability store 10-40% more capacity, have a 4x higher cycle count, and not degrade in capacity over time.” Apart from Gbatteries’ claims of battery efficiency, they’ve also said that the BatteryBox can provide full charge to a 13-inch MacBook Air, along with 55 percent of full charge to a 15-inch MacBook Pro, and 65 percent of full charge to a 13-inch MacBook Pro.
