GPS tracker for bbshd

Hello again. I am looking for a gos tracker for my bike. In case it is stolen. I have found one on aliexpress with a USB chargeable battery. I think it is designed to charge off a car so you can by it with a 12v converter to charge the device. I was wondering if it would be possible to charge it from the 6v light connection the bbshd has? The wall charger does 5v 1a which I think is a pretty standard micro USB charger. Here is a link to the product -

Is there a converter I could buy from the 6v bbshd to charge the 5v 1a gps?

Thanks

Oh - could I use this -
