KFC's new meal box with a built-in battery to charge mobile devices

KFC's new "Watt a Box" is a meal box with a built-in battery, micro-USB, and lightning cables to charge your smartphone. It's available as a special limited edition "prize" for customers at KFC stores in Delhi and Mumbai. BGR reviewed the Watt a Box. It's a fun marketing gimmick but, no surprise, the battery kinda sucks. They claim it's a 6,100mAh power bank but perhaps a better approach (and name) would have been a Bucket of Batteries. From BGR:

The power bank claims to have a 6,100mAh battery but the claims fell short during our brief test. We put an iPhone 5s to charge, which gained 17 percent battery after charging for half-an-hour. But the downside was that the power bank was drained during this process. We recharged the power bank to 100 percent and tried to charge a Redmi Note 3. But the power bank ran out of juice again with the phone gaining just 7 percent of charge...

KFC is not the only one to toy with such marketing campaigns. Pizza Hut came up with a limited edition box in Hong Kong that converted into a projector for smartphones. McDonald's had launched a special edition of its Happy Meal boxes in Sweden that could be converted into cardboard VR headsets. Coca Cola too had a similar cardboard VR headset one could make from its 12-pack cartons.
