TalentCell PB240A1 Rechargeable 22400mAh 82.88Wh Lithium ion Battery Pack with 3 Port Output (DC 24/12V and 5V USB) for LED Light Strip, CCTV Camera, Mobile and more

Does exactly as described , delivering the required 24 V

Brilliant little power pack small in size big in power , I have known a lot of astronomers use these for there goto telescope and it does a great job , I did ask what is max amps it's does say 2 amps but I got an answer back from talentcell that it's 12volt 2 amps but more like 3 amp max Be careful as this is 24 volt and 12 volt I was going to cover the 24 volt up but this is used to recharge the unit , so recheck connection before you power up

Output is not 24V DC, more like 29V DC due to charger provided. So be careful what you’re using the battery for, or use a different charger.

I bought this so I could use my Resmed Autoset 10 CPAP at a festival. I had to make a custom cable to do this. The CPAP needs GND on the outside of the connector, +24V on the inside, and +3.3V on the center pin w/ 2.7k series resistance. Used the "+24V" connection for the +24 and GND. Didn't break my machine but be careful. For the +3.3V, I used a 2.7k and 5.1k resistor as a divider and connected it to the USB. Works perfectly as long as the battery is fully charged. It becomes less reliable when the battery is not fully charged. This will be due to the voltage under +3.3V anyway. Blame Resmed. Consider using a regulator instead as itll be more reliable. Would estimate about 14 hours of use from a full charge. If you are at a festival, ask the welfare team and they will probably charge it for you, free. Beats spending £500 on the official part.

I needed a small 24v portable power supply for programming and this is perfect 🤩

......I don't know why Amazon has asked me to treview its "thickness" or its "night vision." LOL Anyway, I suffer a lot of lower back pain, and found a mains powered (via a transformer) infra-red heat pad that really helps me. I discovered the heat pad requires 24 volts DC, and is rated at 30 Watts. So, by connecting the heat pad to this battery pack, and popping the battery pack into a shoulder bag or coat pocket, I can go out and still receive relief from the heat pad. I've only used it like this for max durations of 4-hours at a time, but the battery pack would last longer before needing a recharge.

Great battery but has a fundamental design flaw. The 24V input/ouput port is exactly the same size and is next to the 12V output. It's very easy to plug one cable into the wrong hole and put 24V out rather than 12V. As the signage on the battery is grey on black (next design fault), you don't notice the 24V output option. Take note and make sure you don't make the same mistake as me. I admit my mistake but having a different adapter would stop this mistake happening. I've brought it today and it's going back and I'm going to get a different battery to ensure I don't make the same very, very expensive (£259) twice.

Holds charge for almost a week. Allows high current discharge

Muy buen producto. La carga da por mucho. Muy sólido y entrega rápida

J'avais eu l'impression de faire une très bonne affaire, je l'utilisais comme une batterie de type V-lock pour alimenter caméra et enregistreur externe (Atomos Ninja V), en bidouillant un attache cela me revenait à plus de 3 fois moins cher que les systèmes classiques. Elle a servi pour 3 tournages en gros, est restée sans utilisation un petit moment (stockage au sec), et là j'allais la reprendre pour un autre projet et elle ne se charge plus. Bref, poubelle (de trie ;-) ) Donc voila un produit pas cher, bonne autonomie, mais...jetable !

Acheté comme batterie longue durée pour une Blackmagic pocket 6K, testé pour au moins 3h30 de rec sans interruption, et il restait encore de la batterie. Donc très content. Par contre j’ai dû acheter un adaptateur pour prise UK vers Europe, non fourni. Et il faut acheter un câble pour aller de la batterie à la caméra aussi, mais ça se trouve.

La batterie ne fonctionne plus, est-elle garantie?
