TalentCell Rechargeable 12V 6000mAh/5V 12000mAh DC Output Lithium ion Battery Pack for LED Strip/CCTV Camera/Telescope/Modem and More, Portable Li-ion Power Bank with 12.6V Charger, Black

I bought this to use with my Spectra breast pump so that I can use it without being attached to the wall. OMG life changing!! I've been exclusively pumping for 5 months and while it can be draining it is giving me the will to keep pumping for my baby. I'm able to get up and walk around, wash bottles, etc while pumping. It's worth it's weight in gold! It's so lightweight and the battery life is insane. It does take a few hours to charge and I charge it about twice a week. It has yet to die on me, but I don't want to risk the battery being dead when I'm needing to use it. I'm very impressed with this battery. If you're debating on purchasing just stop and buy now!!

I was looking at my old purchases and came across this purchase from May 2016. The battery bank still works! It takes a bit longer to charge than when I first got it, but the storage charge is amazing. I've come back to this battery months later and it sill has the charge from last time. The 2016 model is hefty, it has survived drops, doesn't heat up much during use or charge, and feels well built. Only bad part is that the indicator led's are starting to fail after 9yrs. Great product!

This is a great solution to run my aux lights from. I spent many hours trying to determine how I could install my lights without draing my cars battery. This is it. Super pleased I was able to find it

I was impressed with how quickly the item arrived—it felt like it was here in no time. In terms of performance, it charges itself at a remarkable speed and also charges other devices with great efficiency. The quality is excellent and feels very reliable, which makes it worth the investment. I would highly recommend it to others looking for something that delivers on functionality. While it is a bit bulky, that doesn’t take away from its usability—it’s highly practical and gets the job done beautifully. Overall, I’m really happy with this purchase and think it’s a great addition to anyone’s tech collection.

These are nice battery packs that perform well, however when bench testing (at 1 amp) I'm seeing 4 mAh of capacity, not the rated 6.

Having reliable power is very important to me. I have several UPS at home to protect my home lab and basic infrastructure. I use this to power my ISP's ONT device so that even if the power goes out, my Internet connection is not reset and have to reconnect everything. With the large battery, it should provide for even a couple of hours of down time.

Killer works with my Milwaukee electric jacket it will run full day on charge and charge phone too

Great alternative for my Milwaukee heated jacket. Comfortable size and shape for tucking out of the way when in use. Long lasting and functions as good as original Milwaukee.
