Fast-food chain KFC makes interesting action in India. Instead of ordinary box with lunch, visitors of KFC in Delhi and Mumbai can get their orders in special box Watt a Box. It equipped with battery and allows to charge mobile gadget, while its owner is having a lunch.
In box, you will also find a microUSB or Lightning cable. If you want, you can take out the battery out of Watt a Box and take it with yourself separately. KFC announces about 6100 mAh capacity of battery, but it looks like organizers of action accidentally added superfluous zero. Journalists of local branch of BGR were able to charge iPhone 5s only by 17%. And with repeated test with Xiaomi Redmi Note 3, it was charged only by 7%.
