The fast and prompt delivery of the product was great. The product quality is good and easy to use. In my product, this charger product is used together with M28 Bluetooth 4.2 Audio Receiver Module (With 3.5 mm Audio Interface Lossless Car Speaker Headphone Amplifier Board Wireless Refit) to listen music from the mobile phone. The boards are separated by a acrylic sheet and a clear sleeving is used to hold them together. The 18650 battery used is Panasonic 3500mA. It works perfectly well.
prima 18650 battery driver with 5V/4A, 3V/1A each with three ways to solder additional pin's... top price performance ratio
Good Product, Item Quantity is Very Good
Conjunto de 3, porque por engano troquei polaridade da bat.18650...
This is a realy ups for your Rpi. Because a netfail is always for a very short time, you don't have to be afraid for deep unloading of the battery. Also protected for overcharge and deep unloading. In test it's works fine with a back up time for more then 2 houres at least.
The micro USB port is a bit flimsy. Put a piece of wool or a ribbon under your battery to remove it from the holder.
perfect
Perfect for home automation project.
Good quality. Highly recommend
Excellent product, well packaged and delivered quickly, will buy again
