Pike Posted October 15, 2022 Share #1 Â Posted October 15, 2022 Advertisement (gone after registration) I have recently become interested in astro photography and in particular star trails and anticipate taking up to 300 x 30 second exposures to be stacked together in startax software. I understand from the user manual the SL2 can only be charged in camera with it switched off but, recently watched a YouTube review of the camera where the reviewer said what a cool thing it was to be able to use the camera while being charged by a power bank. Â Can anyone please advise which is correct. Link to post Share on other sites More sharing options...

Paul2660 Posted October 15, 2022 Share #2  Posted October 15, 2022 You can use an lithium external battery and power the SL2 via the USB-C port. Works great and gives much longer life. The brand I use is ravpower. Make sure you get the version with a USB-C port.  Paul Link to post Share on other sites More sharing options...
Photoworks Posted October 15, 2022 Share #3  Posted October 15, 2022 You can use the power grip with 2nd battery in it. You can also use a Battery USB-C PD Power delivery Power Bank. When the camera is on it will trickle charge the internal battery . You can also do both options at the same time. Turn on the option Charge over USB in the camera. I have a few of this that work well. https://a.co/d/1GUx87H , but there are many options. Link to post Share on other sites More sharing options...
LocalHero1953 Posted October 15, 2022 Share #4  Posted October 15, 2022 I have not used a power bank, but I have recorded video while connected via USB to mains power. It gave me more than enough power to record till I ran out of card space, but not enough to maintain the battery at full power - it slowly declined. Link to post Share on other sites More sharing options...

Works perfectly with all my Digital cameras to include the SL2. If you signup for RAVPower emails, you might be able to stack a few discount codes for a much lower price than what is listed:  Link to post Share on other sites More sharing options...
