The single was written by David Ciente and Trey Campbell, while production was solely handled by Ciente. Jonathan Currinn, writing for website Celebmix, described "Boom Pow" as a "progressive" song incorporating both europop and "over-the-top" dance styles in its composition, further labelling its sound as "mature", and noting the use of "pulsating beats" and "bass-infused synths" in the recording's instrumentation. About the track, Stan confessed in an interview that its lyrics "fit perfectly with the vibe of Constanța, which adores. 'Boom Pow' is for sure an invitation to dance and to a good time." While Currinn named the text of "Boom Pow" "catchy" and praised Stan's vocal delivery, Los 40 Principales stated that "no summer is complete without summer bet destined to become a summer song", and further felt that the singer tried new sounds with which she hadn't worked prior. Commercially, the single debuted at number 72 on Romania's Airplay 100, and went on peaking at number 67.
Music video
An accompanying music video for "Boom Pow" was shot back in April 2016 but remained unreleased until August 2016, although the singer hinted its premiere through various posts on social media. Together with the track's artwork and a statement for her fans, the visual was finally released on 24 August 2016 after her previous single, Écoute, reached 10 million views on YouTube. It was filmed in various locations of her home town Constanța and in front of her residence there by Ironic Distors—who also served as the director of photography—and features an appearance from her love interest Bogdan Staruiala. Make-up and hair styling was managed by Alex Ifimov and Ema Banita, respectively. About the clip, Stan confessed that she " the summer and the water, the child of the sea. wished a 'hometown video' for a long time ". The clip opens with a shot of a sea, and Stan laying on a rock with a pair of white boots designed with her name on them. Subsequently, she is seen dancing in a place sprayed with graffiti and sporting an orange swimsuit paired with a bright blue jacket. Next, while a few males are playing basketball in front of her, she is portrayed watching and interacting with them while wearing a khaki jacket with denim short shorts, a white vest top and white shoes. After the singer and the others further walk through their surrounding and perform to the track, the visual ends with Stan leaning on a wall from the beginning. Jonathan Currinn, writing for his own music website, described the visual as "relaxed and calm", further stating that the video gives an "insight" of the singer's personality, which can be "constantly seen on her Snapchat stories." He ended his review by concluding that it "may not have a high-end budget, it may not have the best camera work, but it's probably one of most real videos, and I can't help but appreciate the rawness of it."
