[size=+3]Keeppower 18650 3500mAh P1835U (White-blue) 2020[/size]
Official specifications:
A 3500mAh protected 18650 with build-in USB-charger.
A pack contains two batteries and a dual usb charge cable.
The two cells tracks nicely and can handle more than 7A before getting too hot or protection will kick in.
It looks like the USB charger reduces current probably due to temperature at the start of charging.
[size=+3]Conclusion[/size]
A good protected battery with good capacity, the USB charging can be useful on the go or if you only have a few 18650 batteries.
