Homemade Mobile/car Charger

In today's era, we can hardly live without chargers. Imagine that your mobile phone is out of power, it would be a headache, and today's mobile/car charger DIY works can help you solve this problem, or it is more like a power bank. Of course, you can also integrate this circuit into the car's cigarette lighter. The mobile charger DIY can be used almost anywhere we need.

It can be directly connected to charge our mobile phone or power bank. Of course, if we are traveling outside and there is no device to charge the mobile phone, we can use today's DIY to charge the mobile phone with ordinary batteries. Since the input voltage range of the charger is 9-15V, you can use several 18650 batteries or ordinary 9V batteries as power sources. Of course, you can also integrate this thing into the cigarette lighter in the car to charge your mobile device. Go comtar technology for more consumer electronic products.
