I’m having trouble charging the Lemfo les1 hour.
So I ordered a second charger.
But I also experienced the same problem.
When I try to charge, the connection frequently disconnects and does not charge.
Charging the phone is very distressing.
When I switched on the previous charger, there was no circuit in it.
Can not I use a charger like the one shown in picture 7?
You could but if you don't know which cables will work for "your" watch and buy a generic cable or one for another brand watch there is no guarantee it will work. I have several different brands of watches and not all cables are interchangeable. Your best bet is to buy the dock for your watch. I have both the LES 1 and the Zeblaze Thor. The charging dock is interchangeable for both these watches.
