Very good indeed. I'll be using these on lots of projects, not just D1. Should power a Pi Zero quite well too, though I've not checked that. For use with D1, I chose to solder the long pin-sockets from the D1 kit into the charger board, then the D1 sits on top using normal pins, this keeps the antenna clear and works nicely in breadboard.

Nice and handy to power your IOT projects. Shame there isn't and on/off switch. However it's not impossilbe to add your own. Having the ability to direct wire the bat positive to the A1 pin of the mini D1 makes it really handy to add a battery level meter to monitor the battery status. For the price a excellent addition to the Mini D1 ESP2866. Handy bit of kit.

Kiváló kis löket és töltőtábla a Wemos-nak. Akkumulátor pozitív lehet csatlakoztatni A0 olvasni akkumulátor feszültség.

Excellent little boost and charge board for the Wemos. Battery positive can be connected to A0 to read battery voltage.

Attention : Pas de protection contre les inversions de polarité ! Si c'est la cas, ça fume une peu ... Mais ça continue à fonctionner ! (en single, avec un module wifi connecté, ça peut être plus grave :-( ) NB : ne délivre pas de 3V3, uniquement 5V sur la pin 5V

When used in conjunction with a LiPo 18650 battery holder, these do a brilliant job of powering both ESP32 and ESP8266 projects.
