With a high 42980mAh capacity, built-in battery management system, and standard DC connectors, it offers reliable, long-lasting power for up to 4 nights under typical CPAP loads. Its physical on/off switch prevents energy drain, and the included charger ensures safe, slow charging for extended battery life. ## Description Product description How to charge safely 1. Connect the wall charger to AC socket first, and the led of the charger will light green. 2. Then connect the charger with battery. Please confirm your device voltage before you use this lithium battery pack. Low voltage devices can't be plugged into the high voltage output port. Rechargeable Lithium-ion Battery Pack is designed specifically to integrate with our Light bars, Flexible LED Lights, or 24V/12V/5V DC electronic device. The Lithium Ion Battery Pack can be recharged without limitations, as the battery is designed for a slow charge process (10 hours for full charge), which helps the battery pack last longer. Specification Model: PB240B1 Capacity: 3.63V/42980mAh 156Wh Input 29.4V/0.95A. Output USB: 5V/2.4A Max. DC port: 24V（29.4V-21V）/5A Max. 12V/2.5A Max. Package content 1x 24/12/5V rechargeable li-ion battery 1x DC5521 male to male power cable 1x DC4017 male to DC5521 male power cable 1x 29.4V AC/DC lithium ion battery charger NOTES Do not use the power bank in places with high humidity or where it may be exposed to wet. Do not modify or disassemble the power bank. Do not throw the power bank into fire or water. Do not place the power bank during charging on flammbable materials such as in the bed or carpets. Review: Sleep testing results: 4 nights achieved by minimizing extraneous draws - What I liked about this battery: 1. physical on/off switch prevents parasitic drain, so the battery stays charged when not used. 2. dual voltage out, 12v regulated and direct pack voltage tap of 29.4-21v eliminates conversion inefficiency for 24v CPAPs. 12v still is bucked down to a regulated 12, but it's still quite efficient. 3. the form factor is great, about the size of three iphones stacked. 4. Standard 5.5x2.1mm in/out plug takes standard DC connectors. 5. BMS successfully prevented over charge and over discharge. 6. Actual measured capacity over five nights of use was 134.2 watt hours. From a 156wh stated capacity, getting within 20 watt hours of stated capacity was acceptable at 86% of stated capacity under load. I call that a success. 7. The battery comes with a matched charger that works well and charges slowly. Slow charging means better saturation and longer cell life. What could be improved: 1. The 12v out plug is an oddball size, but the included adapter cable converts to 5.5x2.1, but the adapter cable has a male at the other end, necessitating bringing a Female to Female Power Jack Barrel Adapter to convert to what the DreamStation cable needs. I expect that the mfr had to use a different standard to reduce user error. Putting a female end on the jumper cable would be a simple, no-cost fix. 2. The LED indicator lights still had two bars lit when less than one night's sleep remained on the pack. Having the LED lights map better to state of charge would help the user know how much is left. Better yet would be a push button activated volt meter instead of the vague bars that don't provide actionable data. Sleep testing for this battery. Note all tests conducted with no humidifier, tube heating off, airplane mode to minimize power demand. Night 1. ResMed AirMini with direct 24v cable. 19.7wh for 7.75 hours of actual sleep. This works out to an estimated 20.3 wh per 8 hour night. Start voltage 29.0, finish voltage 28.35. Night 2. Philips DreamStation with direct 12v cable. 25.8wh for 7.9 hours of actual sleep. This works out to an estimated 26.24 wh per 8 hour night. Start voltage 28.2, finish voltage 26.8. Night 3. ResMed AirSense 10 with direct 24v cable. 33.8wh for 8.6 hours of actual sleep. This works out to an estimated 31.44 wh per 8 hour night. Start voltage 26.97, finish voltage 25.37v. Night 4. ResMed AirSense 10 with direct 24v cable. 34.1wh for 7.63 hours of actual sleep. This works out to an estimated 35.76wh per 8 hour night. Start voltage 25.38, finish voltage 23.07v. Night 5. ResMed AirSense 10 with direct 24v cable. Start voltage 23.42. Battery self-protection circuit cut off the power at 4.6 hours into sleep. Partial night est consumption 20.83wh. My final analysis is that this is an excellent battery system that is well matched to the DreamStation, AirMini and AirSense 10 CPAP machines when additional precautions are taken to minimize power draw. I removed humidifiers, turned off tube heating and put them all in airplane mode. I'm completely confident that I can take any of these CPAP machines camping with only this battery and reliably get 3-4 nights of use without worry between recharges. Solid product, well done. Review: Good UPS for network devices - I got this to serve as a UPS for my modem, router and Yolink hub. I leave this with the charger constantly connected to the 24 volt socket, the modem and router connected to the 12 volt socket ( a constant 11.8 volt by my meter) and the hub connected to the USB socket. I fully charged the battery and then left everything running with the charger disconnected. I measured the current at 12 and 5 volts and the full load on the battery was 16 watts. At the start, the 24 volt connection showed 28.6 volts, and this declined slowly. After 9 hrs 45 mins, the last bar went out on the battery, and the 24 volt connection was at 20.5, so I reconnected the charger. That is exactly how long it should have lasted, since it is rated at 156 watt-hours (16 watt x 9.75 hrs). So, if I have a power outage, my network will stay up for almost 10 hours, and if power is restored earlier, the battery starts recharging, and there is no interruption in network service. I expect, though I haven't tested this, is that if no one is here and the power goes out for over 10 hours and the battery shuts down, it should come back on when power is restored, and also start recharging the battery. It would be better if the unit beeped when the battery was almost exhausted, so I could shut things down in a controlled manner before the power cut out. But overall, this unit works very well for this sort of application, and is much cheaper than any regular UPS with a comparable watt-hour capacity. I wish TalentCell offered this type of system with their larger capacity LiFePO4 batteries. Those who need 24 volts should realize this is NOT a regulated voltage (like the 12 volt output), but whatever the battery potential is at. This will vary from 28 to 20 volts as the battery discharges-all batteries drop in voltage as they discharge. If your "24 volt" device can't handle that variation, consider getting a 24 volt buck/boost voltage regulator. I tested it again after 9 months use, with two PB240B1's connected in parallel, and the power was sustained for 19 hours-see graph. Very good performance. And a year after the purchase, the two batteries kept my system running for 19 hours. I keep it "charged" all the time with a 4 amp charger that maintains 29.2 v. I am happy that it has retained this much capacity after a year. ## Features - If the charger doesn't work, please contact us to replace the charger. Output: 24V (29.4V-21V.
