There was a problem filtering reviews right now. Please try again later.
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.
The so called "pass through" charge meaning charging the device, using the Krisdonia plugged into an outlet while simultaneously using the device, may or may NOT work. The directions say if Krisdonia automatically shuts off, then this will mean that it is telling you: "pass through" will not work. I cannot do this pass through - the light on front and the Krisdonia itself just turn off. However, I can plug the CHARGED Krisdonia into the laptop WITHOUT having the Krisdonia plugged into a wall outlet and charge the laptop WHILE using the laptop. In other words- - I have to unplug the KRISDONIA from the wall outlet before I can connect to the devices for charging them while using these devices. One last detail - This package comes with sooo many wires and plugs that it is overwhelming to see. I am able to use the Krisdonia with just one simple wire provided without any of the adaptors and plugs provided-just a simple wire they provide to connect the Krisdonia to my devices - real simple!
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.

Je ne pourrais plus m’en passer en voyage. Je n’ai plus à m’inquiéter du niveau de pile de mes appareils.
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.
