Krisdonia 100W USB-C PD Power Bank, 64000mAh Portable Charger Battery Pack [PD 3.0 USB-C 100W + DC 12/16/20/24V + Quick Charge QC 3.0 Dual Ports] for Laptop, Tablet, Smartphone, Projector and More

This power bank works really well so far. It comes with a wide variety of adapters, including Apple Thunderbolt, which made me really happy. I didn’t have to go searching for a separate charger. The display showing the current battery percentage is super helpful and easy to read.I also like that it has multiple output options, including a 100W PD port and another that supports up to 24V. It’s compact and portable enough to carry around, which is perfect for my holiday travels. I’m planning to use it with my sound system on the go and I’m excited to see how it performs in real use.So far, no complaints. it’s been a solid and convenient charging solution!

The 64000mAh capacity easily charges my laptop, phone, and tablet multiple times. The 100W USB-C output works great for fast charging my MacBook, and the multiple voltage options are super handy. It’s a bit bulky, but that’s expected for this much power. Great for travel or anyone needing serious backup energy.

Its a great item to charge devices on the go, great quality and charges fast!

It’s not turning off after 3 months of use as UPS.Long press or plug out all cables doesn’t wok.Device doesn’t charges via USB C port and not charges external devices.Brilliant idea of device, but lack of control possibilities (one button) and displays different aspects of functionality (total output, pass through regime)Now I just afraid to keep it in a bag, cause it won’t turn off at all.Long press and display is turn off but in 2 sec is on again.

The media could not be loaded. Long story made short, this product is excellent! I have tested the device and its dc to dc converter is about 96% efficient! No complaint here at all. The charge indicator is not perfectly accurate, but no charge indicator is. This unit outputs 120 watts steadily for an hour and forty-seven minutes! Better efficiency than I was expecting. It recharges very well from a pd charger and I have had no issues. Given the battery's chemistry, I would expect a life span of around 300 charge-discharge cycles. I have not cracked the battery open to see exactly what kind of cells it uses, but on the surface, everything is on the up and up. This battery is certainly worth the price tag!EDIT!!In December of 2022, the battery began having an issue which I posted a short video about. The display is supposed to turn off when the power button is held down for 3 seconds. The display has been spontaneously turning itself back on within about 3-5 seconds of being turned off. This causes the battery to drain itself from 100% down to 1% in roughly 3 days. This kind of full disharging and (presuming you continue to keep it charged) recharging will significantly reduce the lifespan of the battery pack. This may be a glitch related to the battery pack's volatile memory. Allowing the battery to self-discharge enough to power down the display will clear out the volatile memory in the microcontroller that governs the battery pack's behavior. IF, and this is a big if, you can manage to time things perfectly, it might be possible to recover the battery by recharging it by the dc input once the pack has discharged enough for the display to remain off for at least 5 minutes. If this can be done, the volatile memory should be cleared from loss of power and recharging it will restore power, giving the unit a clear memory to work with. If the cause of this defect is an error which occurs in the volatile memory, the display should resume proper operation! I will try this and post results.EDIT! I was able to recover the battery pack via the method I mentioned above. I used an led desk light to discharge the battery until the display could not remain powered. At this stage, the display was flashing on and off. I allowed it to self-discharge over night. In the morning, the display was off due to low voltage. I plugged in the dc charger and the battery came back online! I allowed the battery to charge to 100% and the error was cleared!

Brand new item. I used it for 15 or 20 minutes to test it out. The display dropped down to 88%. I tried to charge it with the provided power supply and with USB C, for hours, and it never left 88%.Edit: I have put this product through one cycle of testing and I have updated my review. I am currently (wanting to) using this to power a Mackie Mix12FX and a Nobsound NS-05G directly from the 16/20/24v port using an adapter from MyVolts and the supplied cable. I am also (wanting to) using one of the USB A ports to power a seven (7) port USB hub. This hub supplies power to two (2) MyVolts USB 3VDC (first MyVolts 3VDC powers three (3) Pocket Operators/Crazy Chain. second MyVolts 3VDC powers a single (1) Pocket Operator), Roland TR-6S, MyVolts USB 9vdc (powering a Korg KP3+ and a Korg Sample 2, MyVolts adapter), and a RetroKits RK006.I have not tested all of this equipment, at volume, to see how long it lasts. (As of writing this) But, it does absolutely power all of this and more.The problems I had with this at first: If you do not pull enough amps, this will automatically shut off. There is now way to turn this device on and leave it on. It auto senses and if it doesn't sense enough being used, it shuts itself off. If you are only charging one small device, expect frustration. Plugging something into one of the USB ports seems to "solve" this problem, by wasting battery essentially. I even tried powering my two channel Bluetooth amp (Nobsound) powering two Bose speakers, from the 16/20/24VDC port and it still shut off. Plugged in a seven port USB hub to one of the USB A ports and "solved" the auto shutoff problem.I was not able to charge this at first? I don't know if you have to discharge it to a certain point before you can recharge it again? If so, that is a horrible idea. I discharged it to 88% and tried to recharge it with the provided 19VDC charger as well as USB C cables, it never raised above 88%.SOOO, I completely drained this. I listened to music for an entire day via my two channel Bluetooth amp (Nobsound), I charged every cell phone I could find. I ran out of things to recharge before I drained this down to 1%. I finally gave up and went to sleep. This morning I attempted to recharge this, using the provided 19VDC power supply. It got to 63% before the power supply got very hot. It stayed at 63% for quite a while. I REPLACED THE PROVIDED 19VDC POWER SUPPLY (19VDC 2A) with a different power supply (comes with the Nobsound two channel Bluetooth amp. 19VDC 3.42A) Absolutely no problems after this. Charged this product to 100%, no heat issues at all.I can not speak for the version of this product that has the built in AC port, only for the 16/20/24VDC version...If you replace the power supply with a higher amp/better quality, it will recharge this product very well. Make sure the replacement power supply is center positive.If the engineers that make this or any power banks ever read this, please get rid of the auto power off function. Sometimes I want to use this product to keep a single, low amperage device, powered for weeks or months... Sometimes I want to power a small music concert in the middle of nowhere. I can handle turning this device on and off by myself, thank you. Maybe a switch to turn auto function on/off?Even using the replacement 19VDC 3.42A power supply, recharging this product takes a day...... A day. If you used it monday, you ain't using it again Tuesday, buy a second one.Edit: I have been using this product for over 5 years and it still works great. If you take a basic usb-c OTC adapter and insert it into the usb-c port, the battery will not turn off and will not waste anything. I don't know if anything has changed in manufacturing over the last 5 years but mine works and I wish I had purchased more of them at the time. March 6, 2025
