Talentcell 12V Lithium ion Battery PB120B1, Rechargeable 38400mAh 142.08Wh Li-ion Battery Pack with Dual DC 12V and 5V USB Output for LED Light Strip, CCTV Camera, Mobile and More

I have to use my cpap machine or I am miserable. The electricity, in Mwanza Tanzania went out about 1 am most nights, so to use my machine I relied on this power pack. This was almost the largest capacity pack you can carry on airlines. It worked so well with the adapter for my Phillips Dream Station, that I keep the power pack plugged in between, my cpap and the outlet at home. If there is an electric outage, my machine keeps running and I keep sleeping. This has been so easy to set up, and use.

I like the compact size and the battery life (so far). Seems to be well built. 38400 mah is a lot of juice. I have high hopes for this device as I am into a solar project so please don't disapoint me. I've purchased three and plan to purchase more. Keep up the quality and you will get fewer complaints and sell more. As of right now I give this a 5 + star rating. It charges all our phones and Kindles and provides an emergency light. No more candles and smelly oil lights in power outage. Really good thing to have during and outage or emergency. I've constructed a 12v dc light out of easy to find materials. This light is easy to build, budget friendly, and is good for a work or reading or camping light.The lithium ion batteries are superior to lead acid by a long shot. They cost more but in the end lasts longer and are more reliable. It looks like we are entering the age of power outages and monster storms. This little device would be worth its weight in gold if your area happened to hit with lengthy outage. It will charge phones for a long time, longer if you have solar panels. I like it. No one is paying me to say this. To the manufacturer I would just say, keep up the good work and put quality above profit, you'll sell a lot of these, I promise you that.

I use this for everything! I originally bought it to replace a small 12v 7ah battery to run my fish finder on my kayak. It can run my fish finder for 3 days!! The 7ah lead acid would die 3/4 though a day trip. This is much lighter, durable and will do the above AS WELL as charge my Iphone 12 a few times, power my LED Nav lights all evening AND I now use it to power a homeade bluetooth speaker! No joke this thing is amazing. I now have 2! I'd give 10 stars if I could.

Very powerful and long-lasting. I've had one of these in use for over a year without any issues. Just ordered another one to use as a backup for our internet gateway. Without it, every little power outage, no matter how brief causes us to lose internet for at least five minutes while the gateway reboots. Having this will also allow continued internet connection during long-term power outages.Very solid product that is worth the price.UPDATEAfter connecting this to our internet gateway, I noticed that the included charger gets extremely hot (like, may cause a fire hot.) I checked the ratings of the gateway, the charger, and the battery itself. While the battery states it can handle loads up to 6A, the included charger only produces 2A. So, what the heck?? How could you operate something that needs 6A with a 2A power supply, not to mention the overhead needed to charge the battery itself.So, basically while it could easily power the gateway, I have serious concerns about leaving it plugged in, which was the reason I bought it. I guess I'll have to return this and look for something more suitable as a UPS.Still a good product and the other one we're using to operate a water pump works fine, but it only gets intermittent use so no worries about overheating.

Long power supply for cpap machine

Since the thing I wanted to power had a female connector, I bought a male-to-male plug coupler (2.1mm x 5.5mm) to operate it. https://www.amazon.com/dp/B07GKMYPJD

I bought this so that I would have a convenient battery to operate my CPAP in case of a power outage. I received the item and it indicated it was completely discharged, so I plugged it in and let it charge overnight. LEDs showed it was fully charged, (4 bars) and the charger indicated the battery was charged, (green light on charger). I put the battery away for 10 days, then decided to try to use it to see how well it would work. I was able to get 2 full nights plus 2 hours out of the battery on my Phillips Respironics Dreamstation 400. On the third night, after 2 hours, the power went out, and I switched to house power to finish the night. The next morning, the LEDs on the battery showed all off. I plugged it into the charger, and had one bar within 5 minutes on the charger. 2 bars within 30 minutes. 3 bars within 4 hours, and I let it charge overnight, even though I had 4 bars before I went to sleep. I am happy with the battery, and think it will be a good addition for my CPAP therapy.

My original battery arrived with a problem. Contacted the vendor talentcell, who immediately shipped a replacement. Excellent customer relations.Second battery working just fine over the past month, 24v and 12v. On/off switch is very convenient, compared to unplugging.Adaptor cable works, but to save space ordered separate small m-m and f-f miniplugs.
