Talentcell 76.8Wh Portable Power Bank LF4100, 12.8V 6000mAh Multi Voltage Power Supply, DC 12V/9V & 5V USB Output for LED Strip, CCTV Camera, Mobile Devices

Second battery works well with a smoke smoker !!!!

Someone else on an Amazon review recommended this for powering their Celestron scope instead of the short-lived internal alkaline batteries. I am very pleased with the value, the relatively small size, and the option to supply both 12-14V DC output as well as 5V for USB. Although this is a lithium battery, it is the much safer LiFePO4 chemistry that won't catch fire and can be recharged many more times than lithium ion or Li-Poly types. I'm a big fan of this stable and reliable battery chemistry. I also prefer the simple green 4-LED bar graph to others that I've seen or used that show percent of charge on a display, or have a blue LED or two without much else. This one gets the job done and doesn't waste energy powering a backlit display. It's also much easier to read at a quick glance, and doesn't throw off lots of light, which is what I need for night telescope viewing. I tied it to my scope's eyepiece holder tray with a bungie cord, and it's there to stay. I have no reservations about recommending it. Great combo of price, size and function. It's also safe to carry on airlines (assuming they understand the differences in lithium battery types).

I bought this TalentCell battery pack to run my Masterbuilt Gravity Series 1050 smoker. The battery pack has worked flawlessly for three years, and many of my cooks are 12+ hours. Recharge time is fast, too. I've recommended this unit to friends with gravity-feed smokers requiring 12-volt power, and everyone likes it.

Great battery pack. I use it mainly in the early morning to power led lights in the back of a box truck. It doesn't like cold weather. The battery level drops fast in cold weather while in the back of the truck, but goes back up when unit is back at room temperature.

Was looking for a battery pack that could charge up my small devices like phones cameras and such. Also serve as a parking battery for my dash cams when not in the car. I purchased this in September of 2024 and the product worked great. I also like the fact that Talentcell gives you a 24-month warranty plus an extra six more months if you get their product and go online to register it, giving you up to two and a half years of warranty. I also like the fact that it's a lifep04 battery and is safer to use. After about 2 years of on and off use, the battery was not holding a charge anymore. It was then, that I test of how Talentcell really backs the warranty. I emailed them and told them what the problem was. And within 24 hours they email me back and wanted pictures of the device and the charger. I took pictures of everything that the battery came with even the adapters. Once they receive the pictures, they agree that they will send a brand new one in replace of the defective one without any other questions. and within 2 weeks I received the brand new product and was back in service again. I will always buy a product from this company because they definitely back their products. Although I know I didn't put that many recharges on the product I do know that some cells eventually get weak and for some reason go bad. And in this case Talent cell really put up good customer service by honoring their warranty. Without any questions. Although some customers may be upset the fact that they requested pictures of the product I understand that they want to make sure that I as a customer, wasn't abusing it in any way or the product would beat up to the point where that would have made it affect it's function. So if you're asking if I would ever buy this product again. An absolute yes! And I also want to thank Rome Jia for great customer service at Talentcell

With a 5.5x2.1mm Car Charger Cigarette Lighter Power Supply Adapter providing the input and a USB 1 To 4 Splitter Charger Cable Power at the output, I have a dashcam and GPS powered by this, with outlets for cell phone chargers, etc. The cigarette lighter turns off when the car is turned off, and the devices stay powered for at least a day when the switch on the device is "on". A very helpful feature is that when the switch on the device is "off", power from the car feeds through it while the car is running, thereby powering the devices; and they turn off when the car is turned off. The latter is the normal operating mode. However, when I am running errands, I leave the device "on" so that the dash camera continues recording and the GPS is ready to navigate.

Great portability, long lasting battery. I have a couple of radios that have no on/off switch but this battery has one which makes it so much more convenient that plugging in and unplugging a power connector every time you turn the radio on. I have this battery and the 2 smaller ones like this made by TalentCell and use them at home and in the field. Well made and durable.

Bought two of these to power dashcams in the parking mode. No major issues so far but here are some shortcomings. 1) With a 2A load the 5V output on one was 4.85V and on the other it was 5.02V. Both are within the USB power specification (4.75V - 5.25V). At no load it would have been nice if both values were close to the upper limit to compensate for the voltage drop in the cables. 2) As seen in the attached photo the power switches are installed in the opposite directions in the two units. 3) It would have been ideal if the charger circuitry was built it and separate regulated 12V output was available as well.

Hasta 12 horas mantiene encendido un modem de megacable.

I'm fortunate to have a hybrid SUV with a 120V socket at the back end. I have two dash cams (different models) to cover the front and back. The battery's 120V charger is plugged into the SUV 120V receptacle, permanently switched on, with one camera plugged into the USB outlet and the other in the 9V outlet. I had bought a female cigarette lighter adapter to receive the male end on the rear camera, and also a DC 5.5x2.1 mm male-to-male coupler to connect the cigarette adapter to the battery cable to the 9v outlet. All parts were obtained on Amazon. After starting the car, with the transmission in park, I tap on the "1500W" icon on the screen and the battery receives the power from the car, if needed. If the battery was dead, it immediately starts charging while operating the cameras simultaneously. When I park the car and turn off the ignition, charging stops and the cameras continue working in the parking mode for as long as there is power in the battery. A full battery runs the cameras in parking mode for about 30 hours. I've been running this for a few days, and that exact routine is followed every time as tested with many short drives and one longer run of about 80km. The battery only gets slightly warm when charging. I am very happy with this battery so far and will update if necessary.

Excelente, dura todo el día de trabajo.

Sorry...could no resist quoting a well-known review chap ;) I bought this to replace a Celestron Lithium Pro power pack which died (grrrr...that thing was expensive!). Anywho, checked a few astronomy forums and several pundits recommended this little guy, so I decided to give it a whirl. I used it on a loaded Celestron CPC1100 in cold weather, and it didn't even break a sweat, still showing 3 bars after about 4 hours. And the best part is that I was able to Velcro it to one of the support arms, so no risk of a tangled cord! I do use a separate power source for the dew heaters, but I am tempted to get a second one of these for them as well.

With so many technology distracted drivers on the road I wanted extremely powerful flashing warning lights on the rear and side of my electric bike. I purchased absolutely everything to build the light unit on Amazon. The Talentcell LifFePO4 battery is providing outstanding performance in powering the 4 ASPL flashing lights. I need to recharge my Rize Bike about every 120 km and the Talentcell can far outlast that charging routine in operating the 4 ASPL strobe lights. Other products I purchased on Amazon to build this unit include the Zulkit Project box, the Dual QC3 12 Volt accessory switch/outlets/volt meter unit, and the cable glands. All great products resulting in successful build.
