For a project this set-up was bought: https://shop.sensestage.eu/nl/batterijen/28-battery-kit-small-400-mah.html It consists of a Polymer Lithium Ion battery (3.7V) with a capacity of about 400 mAh and a LiPo Charger Basic – Mini-USB. Now, for another project we have a Li-Ion recheargable battery, 3.6 Volt (for example this one) Now, the question is if the button cell [...]

For almost all devices we use power supplies which transform AC into DC, adapted specifically to the power needs of the device. This 9 pages in depth post about power and power supplies has been travelling all over internet. Jon Chandler specifically speaks about Wall Warts, the ones who transfer AC to DC. His article [...]
