Many existing portable smart battery solutions are still quite large and you have to remember when you leave home and bring them with you to take charge of your smartphone. Both Sean and Robert have experienced similar problems and have now designed a small but powerful, completely portable smartphone battery attached to your key, called BKEY.
The BKEY does not need to include a battery for the connector, so you do not need to carry extra cables. Its creators have explained: "The smartphone's battery is bulky and will block the headphone jack. Small independent batteries tend to be oversized in your pocket and require cables to make them work. BKEY easily fits in your pocket. Everything is built on the right charge and use it. You don't have to remember to bring a cable or an annoying adapter. BKEY took more than 2 years to develop because we want to get it right. Do extensive market research and After working closely with focus groups, our R&D team found that the vast majority preferred cables, maintenance-free batteries, which are small and convenient for larger, larger charging alternatives that require the use of cables."
