TalentCell Rechargeable 12V DC Output Lithium ion Battery Pack for LED Strip/Light/Panel/Amplifier and CCTV Camera with Charger, Multi-led Indicator Black (3000mAh)

This is my first week using this battery. It is excellent value. I'm using it to power my Milwaukee Heated Hoodie. The general operating procedures for me is as follows: start on high for 20 minutes, then turn down to low. The jacket is warm enough down to about -20°c on low. The battery is slightly bigger than deck of cards, certainly smaller than a cell phone. Light weight , I don't notice it in my pocket. The battery last about 6 hours with 3 lights of capacity left. This would seem to last an estimated 6 to 8 hours on low heat. The M12 battery 3 amp only last about 3 hours and is very bulky in the side pocket I would buy it again.

Works amazing for my pink spectra pump! Fits perfectly in the cup holder. I can get around 10-15 pump sessions on one charge. Comes with the connector and everything.

Works perfect for giving a non portable pump a new free lease on life. Best of both worlds, strong power and portability. We haven’t had any issues with the pack not lasting, but we make sure to plug it in between uses

Used this to make my breast pump portable and it worked amazing! It held a charge for a long time and had enough power to do the job!

Can’t say enough good things about this! I have a spectra pump and bought this so I could be more mobile. Not only am I more mobile but the battery life on this is pretty amazing. It hasn’t died on me once yet. I’ve had it for two days and pump about 9-10times a day. I use the mid level pump settings so that might have to do with the battery life. The brightness of the green lights isn’t at all distracting as well! Super easy to connect to the pump and plug in. As for size it fits right into the cup holder on the pump!
