Product Description

Attention before purchasing:

1. Not TSA approved because of high capacity 185Wh/50000mAh 3.7V

2. Size ( 7.68 x 5.91 x 1.1 inches ) and weight ( 2.55 pounds ).

3. TYPE-C port can't charge 20V TYPE-C laptop as it supports 12V max.

4. Can charge 20V TYPE-C laptop from DC-OUT port with the included TYPE-C converter.

5. Can charge laptops Max.90W-100W.

6. Double click the power button to set the voltage before charging from the DC-OUT port.

7. It will turn off automatically after 1 minute to save power if no device is connecting to it.

Tips:

High shutdown current for DC-OUT port: 5V / 8.4V / 9V / 12V >3A; 16V / 20V >4.7A

If the power bank shuts off after 1 minutes, it's due to the current of your laptop being too high. Please don't use your laptop or close the screen of your laptop, then charging it with the power bank.

How to Check Whether My Laptop Will Cause Power Bank Overcurrent or not?

Please Check the label pasted on the adapter. If the output is more than 4.7A, it may cause overcurrent. So we don't suggest to use this power bank to charge your laptop.

Excellent Power Bank

Reviewed in the United States on January 7, 2023

Color: blackVerified Purchase

I’m mainly using it to power a Positive Grid Spark 40 amplifier. It works very well, but if anything, the Krisdonia is too smart for my purposes.

Since the Spark is not a device being charged, the power bank doesn’t recognize it, and the 1-minute shutdown kicks in. The solution is to plug in a USB device to increase the current draw and keep the power bank on.

This was recommended by many members of Spark 40 groups on FB, and also by Krisdonia themselves. A simple USB light will do.

You could also charge a device via USB while powering the amplifier, but again, once the Krisdonia senses the device is fully charged, the 1-minute shutdown will occur. So for me, it’s a USB light as it requires a constant draw.

While the design choice of needing to double-press the power button to cycle through the voltage choices is a very solid one, it’s a minor hassle but ensures greater accuracy than putting the voltage choices on a slider-switch, for example, which could easily be placed in the wrong position and POOF!, bad things happen!

Krisdonia designed it in such a way that the user HAS to make sure it is in the correct voltage for the customer’s intended application.

What would be a very nice feature would be if it could “remember” the last selected voltage output. Cycling through all the settings to get to 20V (what the Spark needs) every single time the power bank is used is a slight inconvenience.

This suggestion was sent to Krisdonia, and their reply was that they would take it under consideration.

Overall, highly recommended. Fast-charging, long-lasting, so far it’s been very dependable for a number of uses.

Even with its shortcomings, such as having to set the correct voltage every time it’s used, and needing to bump up the draw with a USB device, again, just for my purposes regarding the amplifier, it’s no fault of the power bank’s design, I very much like it and I’ll keep it. I can use it for much more than just powering the Spark.

Great battery pack with one small irritant

Reviewed in the United States on January 8, 2024

Color: blackVerified Purchase

I love this battery pack but have purchased a different brand (MaxOAK) for the purpose I originally bought this Krisdonia for. The power capacity of the Krisdonia is excellent and the selection of connectors which is included covers most common laptop connectors so this can recharge a wide variety of laptops, provided the laptop doesn't require more power output than this can provide. The 3 USB connections (2 USB-A and one USB-C) provide great flexibility. The only slight irritant I found is that when using the cable to power or charge a laptop we have to re-select the proper voltage output each time -- it doesn't remember what we had selected the previous time, which means that we need to adjust that BEFORE connecting to a laptop (or other device we want to power with this). This is such a minor irritation that I still give this unit 5 stars.
Its large number of possible voltage settings means that this Krisdonia unit can be used on a very wide variety of devices. Combine that with the selection of connectors and it's easy to see how flexible this unit is. The USB ports all provide 5 volts (the USB standard) at up to 2.4amps when required (to power a MAC laptop you can't use the USB-C port, you need to use the adjustable power port with the correct connector for the MAC). The USB-C (5V, 2.4A) is great for powering an iPad or other tablet or an iPhone.
Like all such large-capacity battery units it takes a long time to fully charge when it arrives as well as to fully re-charge after use.
This is a great travel companion for those times such as camping or hiking when you won't be near AC outlets and don't want to be stranded without being able to recharge your devices.

Great customer service

Reviewed in the United States on December 21, 2023

Color: blackVerified Purchase

Over time, I bought three of these, two 25000 mAh and one 50000 mAh. These powerbanks are a very good choice for someone needing a selectable voltage output. They look great and work great. The warranty for these powerbanks is one year. However, the 50000 mAh went defective on the second year, and I got in touch with the customer service. After answering some questions about the defect ( was cutting off at around 60% charge) , they said to me that they were standing behind their products, and sent me a brand new one ! Got it two days later ! Everything went smoothly and I just have to say that I don’t remember getting such a great customer service in a looong time ! So don’t be shy to buy from them !

Best Power Bank I’ve ever seen

Reviewed in Canada on April 23, 2021

Color: blackVerified Purchase

Battery life is amazing, it lasts so long. I’m powering my field recorder (zoom f8n) with this and I recorded for half day continuously and it still has 91% power. I also liked the items included in the package. You have a number of adopters so that you can use the power bank with almost any kind of device. In relation to power, this is the best equipment I have ever bought!

It powers a phone, so far

Reviewed in Canada on June 6, 2022

Color: blackVerified Purchase

It was one of the least expensive of this type of battery backup. It's only had a minor test so far, so this jury is still indecisive. If I was able to travel more, and sit in coffee shops to work, this would have had a better test.

Doesn't work while using laptop

Reviewed in Canada on September 26, 2022

Color: blackVerified Purchase

I would have preferred contacting customer service, but no contact information found.

My HP zBook laptop works fine using a 65 W /20 V power supply.
When using my laptop, this charger works for about 10 seconds at 20 V, then stops. I can restart it, but it only ever works in 10 second intervals. When my laptop is asleep, this charger does charge my laptop.

This charger works just fine on phones and tablets at lower voltage, just not the laptop at 20 V.

Very frustrating as my intention is to extend the battery life while using the laptop! I will be returning the unit unless I hear from the company on this.
