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 used it for my spectra pump while I was nursing and it worked amazing, kept my pump running for days, also works to keep my heated sweater warm, and great to charge my phone. Very happy!

I'm an automotive electrician and I modified this to be a 12v test source. I've been looking for a nice little 12v battery to put on my cart for quick testing for so long. This thing even has a nice on/off switch if I feel sketchy about what I'm testing. There's also reverse polarity protection! Ask me how i know.... lol. This is exactly what it says it is. It has been solid for me and endured some loads that certainly explore the limits of what it's capable of.Everyone at work knows what I mean when I say "grab the talentcell off my cart!".Talentcell you should make one of these with just two 16awg wires coming out with a straight wago lever nut on each. It would sell like hotcakes to sparkies.

I bought this portable battery to use with my Spectra breast pump, and believe me, it does exactly what it’s supposed to do. A single charge lasts for days—and just to clarify, I pump every 3 hours, so from Monday to Saturday I use it about 3 times a day, and I only need to charge it once every two weeks.

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.

I recently had the opportunity to experience the exceptional quality and remarkable customer service provided by Talentcell, and I am thoroughly impressed. The Talentcell battery pack exceeded my expectations in terms of long battery life, quick shipment, and their exceptional warranty service that promptly resolved an issue I encountered.The battery pack's long battery life is outstanding. It kept my devices powered so well that I rarely had to charge it. It was perfect for all my on-the-go adventures. Whether it was charging my smartphone, tablet, or even my portable shower, the Talentcell battery pack provided a reliable and consistent power source, giving me peace of mind throughout my travels.I loved their expedited shipment process. After placing my order, I received a notification very quickly, and I received my package really quickly. Nice because I wanted to use it right away.Talentcell also had exceptional warranty service. While using the battery pack, I encountered an issue where it would not charge. However, upon contacting Talentcell's customer service team, they responded swiftly and professionally. I explained the situation, and they immediately offered a replacement without any hassle. I was impressed by their willingness to address the issue promptly and ensure that I was a satisfied customer. Within a short span of time, a brand-new battery pack arrived at my doorstep, and it worked flawlessly.I highly recommend the Talentcell battery pack to anyone in need of a reliable power source on-the-go.

I've been using TalentCell battery packs with my router since 2022, and my original unit, which was a gift from a friend, is still working perfectly. The battery has performed exceptionally well for my needs, and I have no major complaints about its quality or build.The size is convenient, making it suitable for my router and potentially other compatible devices, such as cameras. Charging does take some time, but overall, I've been satisfied with its performance and reliability.Unfortunately, my experience with my latest order was disappointing. One of the battery packs arrived with its packaging opened, without the protective packaging I would normally expect, and with white dust visible on the top of the unit. This was concerning, particularly since I expected to receive a properly packaged item in NEW condition.My disappointment is with the condition in which the item arrived, rather than my long-term experience with the TalentCell brand. Based on my experience since 2022, I still consider the product itself reliable. I just hope greater care is taken to ensure that future orders arrive in the expected condition.

Keeps my telescope powered on for hours

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!

Use it mostly to power motion detected led strips. Battery lasts weeks. Recently used it to power a noise machine during a power outage. Other battery packs would auto shut off since it’s very low power, but this one worked perfectly since it has a power switch. Lasted all night and was still almost fully charged.

Funciona bien. Me hubiera gustado que el cable para la salida de los 12v fuera un poquitito más largo. Fuera de eso muy bien.

Purchased to power my e-spinner. It works well and charges quickly. I'm happy with the size and the connectors provided.

Excelente, hasta la fecha sigue trabajando muy bien, cumple con lo que promete

using to prolong the ZWO Seestar S50 telescope time outdoors by plugging in this external battery to help the internal battery out. It went from about 4 hours with internal battery only to over 6 hours with this new external abttery.
