A proposed class action claims the Pocket Juice portable power banks sold by Tzumi Electronics LLC fail to deliver the advertised amount of power.
The lawsuit explains that Tzumi’s Pocket Juice products allow consumers to recharge personal electronic devices by converting power from their own internal batteries to a voltage that the devices can accept. According to the suit, the one material difference between different models of power banks is their ability to charge a device, which is measured in milliampere-hours (mAh).
According to the case, all Tzumi Pocket Juice products are falsely advertised in that they are unable to deliver the amount of mAh represented to consumers on the devices’ packaging. Although Pocket Juice power banks are represented as able to provide 5,000, 8,000, 10,000, 15,000 or 20,000 mAh, the devices actually have a “substantially lower” mAh capacity, the suit alleges.
The complaint points out that a power bank uses as much as 30 to 40 percent of its own battery power to run its internal circuit board and convert power to charge a personal electronic device. The suit argues that because Tzumi bases its mAh representations on the capacity of the power banks’ internal battery cells, the products are incapable of delivering the advertised amount of power to consumers’ devices.
The two plaintiffs, who each purchased a Pocket Juice 4000, hired an outside laboratory to perform tests on 4,000, 6,000, and 20,000 mAh Pocket Juice models, the suit says. According to the case, the test results showed that 100 percent of the products “do not measure up” to Tzumi’s advertised mAh claims, as the complaint illustrates in the below chart:
The plaintiffs argue that they would not have purchased the Pocket Juice products, or would have paid less, had they known the devices were incapable of delivering the advertised mAh.
The lawsuit looks to cover anyone who purchased Tzumi Pocket Juice products in California, Florida, Illinois, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Texas and Washington.
