Disclaimer: The circuit in use here came from GreatScott: YouTube video related to this project: https://www.youtube.com/watch?v=Fj0XuYiE7HU Thanks for the circuit GreatScott, it really works well! The awesome find of the lipo protection chip with 2.9v cutoff – ruined way too many cells with the DW01’s 2.5v! So, down to business: We all know the frustration of […]

Story Why: We built the Pirl Charger because we were unhappy with the quality of existing chargers. Few consumers know they gradually ruin their expensive devices by using poor quality chargers that deliver high noise, high ripple energy. Every consumer device comes with a charger, and those are usually well-built, but they usually have only

This is my first post so… be brutal ! I have a small yard with a very odd shape, well… L-shaped really and not enough pressure at the tap to be able to water it in one go. So I had to create 3 sprinkler sub systems that can only be turned on one at
When you travel, it’s a bit frustrating to fill your luggage with lots of chargers, cables, and adapters to fit your charging needs. In addition to the space it takes which makes it harder to bring every kind of charger you may need. ChargEST is designed to become your charging companion anywhere in the world you

I built a very simple DIY solar-powered USB charger for my TP-link 10400mAh USB Power Bank. All I needed was a 6V/3.5W solar panel and the TD1410-based 5V buck converter module. I bought both of them on Aliexpress for less than $8. It was one of the easiest projects I built. All I needed to do was to connect
Troubleshooting iPhone problems can be a daunting task sometimes considering how complicated they are. It’s easy to overlook the simple things and on occasion you may replace parts that don’t need replacing. Batteries are no exception. I have seen technicians often replace batteries when they may not necessarily need to be or ignore the fact

Introduction For charging relatively low capacity batteries, or maintenance charging backup and keep-alive batteries, linear topology battery chargers are valued for their compact footprints, simplicity and affordability. Even so, there is a dearth of linear chargers that accept a 10V or higher input voltage, leaving many industrial and automotive systems underserved. Some switch mode solutions
