Just tested my new TalentCell PB120B1, 38400 mAh battery pack with my CPAP machine Respironics Dreamstation @ a pressure of 14 and using a direct connection to DC outlet of PA100). I do not use a humidifier. It ran for three nights (21 hours and 47 minutes) before running low on juice. The Dreamstation is not powered when the battery LED indicator goes down to 1 green LED. Make sure you charge it until the charging indicator turns green and not just until the LED indicator goes up to 4 green LEDs.

I previously used a Paxcess PA100 as my camping battery. It also works well (22:56 before it drained with the Dreamstation) but there is a large size and weight differential. The Paxcess weighs 3.377 pounds and the TalentCell weighs only 1.83 pounds without peripherals. This totals just under 4 pounds with CPAP machine, mask, and DC connecting cord (which I made myself). The TalentCell is less than one/third the size of my other battery and only slightly larger than the regular CPAP DC converter brick "“ which I don't need to lug around. The TalentCell easily fits in my carry-on bag and I will use it for my next camping trip to Japan this month. I also ordered another identical unit to extend my camping time to 43 hours or over five nights between charges.

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.

Cells are marked as Panasonic NCR18650BD, no idea if genuine or not.
Included charger is actually decent and deosnt seem to throw any RF out when tested near a uv-5r
Couldn't find markings on the BMS without taking it to bits, but looks like an off the shelf cheap one
control board looks to be custom and designed for the purpose but I didnt want to pull it to bits either to look it over
Internal wiring is reasonable.

My only problems are while it is very nice of them to not glue the battery in place, the only retention for the cells is high density foam, and that the bom cost is kinda low-ish compared to the price.
The cells are sandwiched in very well from most sides, but there is about 15mm of space between the cells and other components on the side with the plugs. This gap is filled with a chunk of high density foam but it's just placed between the pcb and the BMS.
In short, this means if you drop the thing and it lands flat on the plugs side, it has a higher chance of breaking vs any other side.
The case has a molded in plastic portion which will stop the cells themselves from hitting anything, so there isnt really a risk of short from a reasonable drop.
My guess is they didnt design in a better stop because other configs may use that space for more battery.

edit:
I capacity tested it because I was bored. got 24,750mah at 10W draw tested from USB port. Not the best way to test it as I could feel heat coming from internal board (pretty normal) and this means loss. Not sure what value for loss you want to use here but at 20% loss that's only 30,000mah. To reach design capacity, the USB port would have to be wasting 50% or an entire amp at this load.

I have two sets of photos the one showing mAh is the drain test by 5V battery meter. The other photo of energy usage is a smart wall energy monitor to see how much electricity it needs to fully charge the depleted battery.

For the drain test I kept the discharger at a constant 5V 1A and also tested the max output. Came out to 2.5A, so it can charge/power most devices that you use on the daily. Once you pull around 2.7A that's when the battery shuts off to protect itself/can't output that amount of power. But as you can see I got a pretty low number from 38,400 so that made me wonder how did they get this number? Since there are 12 cells inside and you divide that by 24435 you get 2000...they claimed 3200 per cell...riiiight.

While charging I monitored it every 15 mins to make sure to turn off the charger once the battery was fully charged and it came out to .19kWh or 190Wh so it takes a decent amount to charge. But still, how did they get 38,400? Seems like so number they made up and anyone can say their cells has 3200mAh. Since I had opened up my unit and it was held in with sticky foam pads and hot glue.... talk about quality. So of course, 3200 x 12 makes 38400.

I ran the charged number I got so if we take 190Wh and multiply by 12V we get 15833mAh. Now we need to do a conversion rate from stepping down the 12V to 5V so 12 divided by 5 equals 2.4. 15833 x 2.4 = 37999mAh.

So there you have it, the company did some wild math to claim 38400. Are you truly getting what is claimed...in theory yes but in reality no. Would I recommend this battery? It really depends on what you're trying to power. If it's a medical device sure but for anything else, no look elsewhere.

In short, you are only getting to use 62% of the rated capacity...yikes!

I hope this "review" was insightful and you should know what you're getting before you purchase.

Did a 4 hour 360 booth event with lights connected it to it and it didn't died on me at. It only use one light out the 4.
