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.

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.

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

I purchased this item specifically to extend the battery life of a mini HD camera that overlooks my front door and sidewalk for security purposes.I also purchased this item in particular because of the many positive product reviews. So now I will contribute one as well because those reviewers were absolutely right.This was my first purchase of any type of portable battery pack, so I was unsure of what I needed specifically. I came upon this product because the description specifically mentioned use for wireless/hidden cameras.After reading the reviews, I purchased this item and I was not disappointed. It truly extends the battery life of my camera, and not just by a small amount. It's added several hours of additional runtime. I cannot fairly give an estimate as the battery usage depends on how often my camera is triggered by motion. But on average, it has at least extended the battery life by 10 hours - and that is a fair estimate as I do not wish to create higher than normal expectations as I'm sure it varies amongst devices used.The maximum hours of extended battery life I have achieved is somewhere between 48 and 50 hours of additional runtime, however, that does include the 7-8 hours of battery life from the camera itself.To summarize, this device has been such a fantastic and helpful addition to my camera setup. It's easy to use, easy to recharge, the AC adapter includes a small status indicator light on the plug that displays red for charging/needs charging and green for fully charged. There are also 5 very small status indicator lights on the actual battery pack itself.I'd like to personally thank all those who left honest product reviews as this was what determined and encouraged me to purchase this specific item. It's great for a host of other items which I realize I did not include, but that is simply because I have only used this item for one specific purpose. I cannot comment on other applications as it would not be a honest assessment. I do highly recommend this battery for anyone searching for an affordable solution and quality portable battery pack!

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.

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.

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.

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.
