DC 12/9/5V Output Lithium Iron Phosphate Battery Pack

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).

A while to find a replacement battery for my O2 portable tank. Value for the money nice.battery life-4 hours. Easy to use. Size is OK. Functionality is great.Thank you. Regina

I use the TalentCell 12V LiFePO4 Battery Pack in my garage to back up my 12 volt ONT for any power outages. Very well designed and easy to use. It comes with exactly the right cabling and power supply that I needed.

Would be improved with charge percentage display. Must be charged on AC (says that up front) so not as versatile in charging. But, it does supply more-than-good-enough, steady 12V for 5.5x2.1 male to cigarette lighter female to flush automobile USB-c PD charger. Comparatively compact. There's a complaint about not solar charging...it's not designed or advertised for that...get a Jackery or similar if that's your application. If you want a very portable 8 hour power supply for remote laptopping, this works.

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.

I've been keeping my home online through power outages with these for years now. Much safer than Li-Ion cells.

Great for my Blackmagic Pocket Cinema Camera 6K Pro.I've used it with the 4K, 6K and 6K models without complains. It's really versatile and cheap (way cheaper than a V-Mount), it definitely does the job. I'll last for about 4 to 5 hours depending on the record method and settings. I've two of these and one of the non-Nominal-11,000mAh model but this last one will last less since at lower battery levels it delivers less than 8V while this Nominal model does deliver 10-11V even at its last percentages.

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.
