Review on TalentCell 12V Lithium-Ion Battery Pack For LED Strips, CCTV Cameras & More – Rechargeable With Multi-LED Indicator by David Boulanger

Bought it to make my spectra s2 breastpump portable. Much better value than paying the upgrade fee to insurance for the s1. I bought heavy duty Velcro and attached it to the bottom of my pump. It works really well! I have to agree with someone else who mentioned you do notice your pump’s suction decreases a little if your battery life is low (but I didn’t take note of how low it was at the time). I like to leave it charging overnight so I don’t have to be plugged in during the day. I haven’t even paid attention to how long it will last but it’s only ever died on me once after not charging for a few days so I’d say it’s great!
