Compact design and multiple connections mark the i2GO I2GBAT011
Focused on extreme portability, this i2GO device stands out for being just 15 millimeters thick and weighing a light 222 grams, easily fitting in your pants pocket. Its internal reserve of 10,000 mAh can be distributed between three different ports, two in the traditional USB-A format and one USB-C, which makes it possible to power a trio of electronics simultaneously. A built-in smart chip reads the connected device and sends the exact electrical current it supports.
The power bank recharging process takes around five hours using 5 V/2 A connections, according to official data from the brand. Built with highly durable energy cells, the device carries quality seals from bodies such as Anatel and FCC. Costing around R$79 on Mercado Livre, customers tend to praise the ease of handling and the technology that allows the cell phone to be charged while the external battery itself is connected to the socket.
