Talentcell12V Rechargeable Lithium ion Battery Pack, DC Output for LED Strip, Heated Jacket, Spectra Pump, CCTV Camera and More, 11.1V 6000mAh Portable Li-ion Batteries with 12.6V 1A Charger

This is an excellent battery pack that works flawlessly with both my Zoom F8n Pro and my new Koma Elektronik Chromaplaine. I needed a reverse polarity cable for my Chromaplaine, and Talentcell sent me one at no cost. I would have been happy to have paid for the correct cable. Excellent and generous customer support!!! Highly recommended.

I don't think there is one universal reason people would buy this battery pack. And that's the beauty of it, this thing has many and varied uses, to many to list. Mine is perhaps one of the more unusual ones, but perhaps after reading this there will be more people trying it out this way.Start with the fact that there are all kinds of battery packs listed here. But I didn't want to kludge around, I wanted to use it as much as it is as possible. That means charge it up, plug it in, and go. My use was to add two high power lights on my golf cart to help navigate hilly terrain when it gets pitch dark and those little flashlight bulb type lights that are mounted low on the front of most golf carts just aren't adequate. I got a couple of really cheap but bright LED lights that are designed just for this purpose, mounted them to existing holes in five minutes and I could have wired them to the existing battery terminal that already has a step down transformer from the cart's 36 volts but I didn't want to add to the drain of the batteries of an all-electric cart so I just ran the wire down the side of the windshield and terminated it into a standard DC connector to plug right in to this battery. One really nice feature of this is it has a simple rocker switch to turn it on and off and a simple built-in status monitor. When the battery gets low all I have to do is grab it off the dash and take it indoors to charge it up.PROS AND CONSThere really aren't any major magical things about this battery nor are there any big negatives. It is almost the size of my smartphone but about four times thicker. It weighs about a pound. When charged I measured the output voltage to be exactly 12.7 volts. They have apparently made a few design changes without telling their marketing department, such as they indicate there is an LED status light on the pack itself but that is covered with a blank plate and the status light is on the wall transformer instead. That doesn't affect operations in any way, it still glows red while charging and turns green when ready. They don't mention the five tiny lights on top of the case bit these tell the user approximately how much power is left.From their ad the company doesn't seem to be sure how this would be used either. That results in including a rather odd split wire dongle that has two male and one female connector. I guess they assume some people would want to charge their battery while it is in use, which is possible. Unfortunately it would probably have been more useful if they included a simple cable that had a male end on it and one that ended in bare wires for experimenters. That's not really a big deal though.CONCLUSIONThis pack works as it should, delivers the expected power, is small, lightweight and rugged enough for hobbies like model airplanes, drones, boats. The price is exactly what I would expect to pay. I like it and believe it earns five stars for all of the above reasons.

The media could not be loaded. Works great to make a breast feeding pump portable! It even says in the little brochure with it that it is designed for nursing pumps. Got this idea from a video on YouTube and she recommended this battery pack. Also search for “heavy duty Velcro strips” on Amazon so you can attach it to the bottom of the pump and you’re set. Included is a video I sent to a friend because I was so happy about it :)

Great product.

When working, this is a 4-5 star product, but after 7 months mine is not holding a charge and failing to charge properly. I've reached out to support to see if they can make it right, but until then this is a 1-2 star product.UPDATE - Talentcell was very fast to respond and make the issue right. The service was 5-star. Upgrading the battery back to 4-star, and I'll move it to 5 if this replacement battery holds up longer than the first.

I have bought 2 of these. They are great for powering WS2815 addressable LEDs. One of them can run a strip of 300 without too much problem for several hours even though the strip max current pull is more than this is technically rated for. The usb port is also quite helpful for providing power to a esp32 or some microcontroller to power the leds.

I design electronics kits for a living and for one kit in particular which had a 20W+20W amplifier, my customers needed a portable 12V power source capable of supplying at least 2A. My customers and I have purchased a lot of cheap blue and black brick batteries from China through ebay, and time and time again they've failed after a few charge cycles, and upon opening the batteries up, I found the cells inside were not only lower capacity than advertised (3200mAh in a battery advertised as 9800mAh @ 12V) but also used, and several years old! The chargers supplied were also far too weak for the job, being rated for only 150mA in one case, resulting in a charge time of over two days!I finally decided to give Amazon a shot and after seeing that this battery had good reviews and pictured a 1A charger I decided to order one. When it arrived, packaged very nicely, I could tell just by the weight and feel of it that the build quality was much better than some of the other similar looking batteries I've tried. I also noticed the two halves were held together with screws, which meant I wouldn't have to destroy the thing to peer inside. So I decided to do a tear down.As you can see in the photos, this battery is very well built, and uses cylindrical cells which are supposed to be a bit safer than the pouch cells, but weigh a little more and take up more space. The circuit board itself also appears to be well constructed. Most importantly though is that you can see the cells are stamped with a date code that indicates they were manufactured only two months ago. No recycled cells here!Finally, after tearing down the battery I reassembled it and charged it up and it works great.So for the price this is the best no-frills 12V battery pack I've found. It's only a little more expensive than the fake Chinese batteries, it arrived in a week instead of 4-6, and it looks like it should be reliable for years to come.I will note have seen a few reviews stating that the battery would not take a charge. It's probable that those people did not turn the power switch on when charging. While it seems like you'd want to do that, the switch must be on for this battery to charge. Which is perfect for my installations actually, where the battery is inside an enclosure with no access to its power switch. I just connect it to an external power switch and charge port with a wire harness that makes use of the included Y cable, and I'm good to go.
