Rechargeable batteries with C-Type charging facility

My son likes a lot of electronic items. When it comes to electronic items, it requires batteries. That is when I saw this rechargeable battery from the Portronics brand. Anything to do with Portronics, I'm a huge fan because they come up with products with greater innovation that are very useful for people to consume. This is one such innovation where we can use a rechargeable AA or AAA battery rechargable and I can even recharge those batteries directly through a C Type charger.

When we buy this product, they include a small, sturdy box to keep the batteries safe. Along with that box, they provide a cable where two batteries can be connected at the same time to a single USB wire. This is nice again because otherwise we have to wait for one battery to charge fully before charging the other.

When it comes to backup time, I noticed that the battery takes about 1 hour to fully charge. They have a light in the battery, which makes it look very good when charging is happening. The light keeps blinking until the charge is happening and after the charging is done, it stays on. I needed this because it has always been very difficult to buy regular batteries for my Son's toys. That's the primary reason why I wanted to buy rechargeable batteries. Some toys specifically mention that we shouldn't be using rechargeable batteries, but in many toys, it will keep working regardless of the batteries we use.

I don't know who came up with this innovation first. The reason is that I'm able to see many companies have started launching their batteries in this format, where charging can be done with the help of C Type wires. I would like to keep using this product and see how it goes.
