Energizer Brands, LLC makes an Energizer Max PowerBank portable charger that can be used for recharging phones and tablets that promises 10,000 milliampere hours (mAh) of charging capacity. But the complaint for this class action alleges that this rating is false and misleading and that users will not get anywhere near 10,000 mAh of charging capacity out of the device because its capacity has been improperly calculated.
Two classes have been defined for this action:
- The Illinois Class is all persons in Illinois who bought the product during the applicable statutes of limitations.
- The Consumer Fraud Multi-State Class is all persons in Utah, North Dakota, Kansas, Mississippi, Arkansas, Alaska, Wyoming, and South Carolina who bought the product during the applicable statutes of limitations.
Consumers sometimes need to recharge their devices even when they do not have access to an electrical outlet. This is the role played by power banks like the Energizer one. According to the complaint, the device contains a battery cell along with a circuit board to control the current.
Page 1 of the complaint shows the packaging for the product, which includes the power bank’s rating of “10,000 mAh” in larger letters and promises “36 hrs for smartphones, 16 hrs for small tablets, 8 hours for large tablets.”
“The Product’s mAh is based on an average voltage of 3.7 volts,” the complaint alleges, “while an electronic device such as an iPhone operates on 5v.”
The complaint then outlines the first problem: “While the Product is charging a device, 3.7v must be converted to 5v, reducing the amount of available mAh.” The complaint thus calculates the power bank’s capacity as 7,400 mAh—that is, more than 25 percent less than advertised.
But the complaint then estimates an even lower capacity for the device: “Given that the conversion efficiency for the Product is between eighty and ninety percent, the usable/output capacity is only between 6,000 and 6,600 mAh, substantially lower than the 10,000 mAj promised.”
A full 10,000 mAh, the complaint alleges, will charge a smartphone with a 3,200 mAh capacity more than three times, the complaint alleges, but with this more accurate calculation it will fully charge it less than twice.
According to the complaint, because of its false representations, the power bank is sold “at a premium price” of at least $29.99, but the complaint alleges that “[t]he value of the Product that [the plaintiff in this case] purchased was materially less than its value as represented by” Energizer.
