The SJ1000 action camera is just great. Picture and sound quality are excellent. The Aku duration sufficient for operating standards. But if you make a bike tour or the SJ1000 is used as a reserve Dash Cam Aku beneficial. The charging time with the Charger is ok. There is no LadeLED display. I have therefore taken just after 2 hours the Aku again from the charging cradle. That was sufficient, since I got in the Action Cam "voille charge" appears. A micro USB charging cable was also there. Yepp. I can recommend.
