2 in 1 Charger and Power Bank

The Nitecore F4 Charger is a lithium-ion battery charger and power bank all rolled into one. The F4 has four independent charging bays with a max charging current of 1A for quick recharging of 18650 Li-ion batteries in any discharged state. The LCD screen displays real-time information like output volume, battery voltage, USB output current, charging current for immediate assessment of batteries; it also comes with an energy saving Hibernation function which will shut down the screen if there is no operation for 10 minutes. To use the power bank feature, simply plug in a USB cable and effectively charge up electronic devices. The Nitecore F4 can fully charge an iPhone X in 2 hours; not only can you bring your 18650s back to life, but also your phone!
