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

This was exactly as described and has worked very well for the last month. It was bought as a power supply for a portable stereo using a 12 v car receiver. It runs for several hours on a charge and takes several hours to recharge but I have not timed that exactly. It does not get warm and is way less money than most battery packs of a similar capacity. My only complaint and it is a small one, is that you must unplug the 12 volt output socket to put in the charging cord. It also requires you to know that the power switch must be on in order to charge the unit. Even if off, the indicator lights come on, giving you the impression something is happening.So, be sure you read the instructions before using it. Although it states it will put out 5v usb, I do not think I would have bought this unit for a 5v usb battery pack. There are similar packs of similar capacity that are much cheaper. However there were few for 12 v output. So it fills the bill very well and is much lighter and cheaper than an equivalent lead-acid 12 v battery.***This is an update. I have had it for 10 months now and I use it for a few hours every weekend to power a portable USB speaker. It is still going strong and has been very reliable. Given that there are basically no other comparable units I am very happy with this unit.New update: I have had this unit for over 8 years and it is still running well. No failures, no problems except it takes a shorter time to deplete the charge. But for an 8 year old pack, it is doing really well.in fact, just because it is still working, I'm adding a star.

Super long life and does what I need. I bought this as a backup power source for our Owlet baby monitor for if we lose power.

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 humble power source, though small in stature, is mighty in performance. It delivers a steady and reliable current, ensuring that all manner of devices, from lanterns to lutes, are powered with unwavering consistency.The lifespan of this battery is commendable, lasting far longer than many of its peers. Whether in times of peace or moments of need, it stands as a steadfast ally, ready to provide the energy required.One must also admire its ease of use. It fits snugly into any coat pocket, and its construction is both sturdy and safe. Verily, it is a product of fine craftsmanship.Yet, no tale is without its minor flaws. While this battery excels in many areas, there are rare occasions when its power does wane slightly quicker than anticipated under heavy usage. However, this is but a small blemish on an otherwise exemplary record.In conclusion, I bestow upon this battery a well-deserved 4 out of 5 stars! 🌟🌟🌟🌟 It is a reliable and valuable companion for all your power needs.
