Hello, I have a tracker Simvalley GT 280, which has a battery of 700 mA. The battery alone, however, only lasts about two days with a daily query. In order for the tracker to remain functional over a long period of time, I connected it to a 12,000 mA power bank, hoping to be able to rest for about four weeks and maintain the function. The power bank itself should be charged with connected vehicle. The problem: the battery en s Trackers emptys (despite the connected power bank) so that I get a message to the battery level at 20% residual charge. Obviously no compensation is made via the powerbank. But when I pull off the charging cable and connect again the battery is charged in the tracker (red indicator light lights). A charge is also done if I press the button to check the charging state on the power bank. What can I do, or must I change that the current is directly from the power bank. Powerbank? Who can help me?
