Chapter in this post:
Ugreen recently sent me a new power bank (thanks for that!), Which comes with two, no, three nice features:
I would like to deal with the "specs" first, so that you have a rough overview of what the battery has in terms of input and output.
Two more small notes:
What some of you may have noticed when skimming the technical data is the indication of the nominal capacity with "only" 6250 mAh. Most power bank providers like to ignore this additional information. For advertising purposes, they only indicate the capacity of the built-in battery cells, which is, however, always significantly more than the capacity that can be found at 5 volts.
For this reason, I have been advocating for years that one shouldn't mAh information does more with power banks, but simply indicates the watt hours (Wh), because this unit includes both voltage and capacity. This would give you a value that could be used very well to compare the individual power banks.
Ugreen advertises 20 Watt output power via the USB C port. To check how it behaves in practice, I connected my MacBook Pro (Intel) to the power bank. While this is not the intended use as the power bank cannot seriously charge a MacBook Pro, I was sure that the maximum performance was being obtained.
In my measurements came too 20 watts from the USB C port - just as promised by Ugreen.
While loading mine iPhone 12 Pro Max flowed a good 15 watts into the smartphone.
My iPad, on the other hand, was able to use the power bank USB A port with 4,9 volts and 2,0 amps - just under 10 watts - charged. On the USB C port was even with 4,9 volts and 2,3 amps loaded. Why not with more power? Because this iPad is older and not yet USB C Power Delivery unterstützt.
The values are all very good and show that the power bank is quite suitable for charging an iPad or iPhone.
For a MacBook Pro, on the other hand, I would recommend a larger power bank with 26.800 mAh so that the laptop noticeably gains operating time. The number of watt hours from the Ugreen PowerDot Powerbank is roughly half that of a 13 inch MacBook Pro. If you also assume an efficiency of 80% when charging, then with a complete power bank filling you gain maybe 20 to 30% battery level with the MacBook Pro.
Apart from the technical values, the PowerDot Powerbank is a really helpful device if you use it in everyday life. My children have used them more often in the last few weeks to charge their iPhone and iPad and it has always been particularly practical that the Lightning charging cable is attached to the power bank. This eliminates the hassle of searching for the right charging cable.
Furthermore, the versatility of the connections is very pleasant: From USB A to USB C to Lightning, everything can be plugged into the Ugreen PowerDot battery.
I think the power bank is very successful, especially when you see the price of around 23 euros, for which it is currently listed on Amazon. Nevertheless, from my point of view it is a good power bank for on the go, for hiking, cycling or for similar activities.
The power bank is available in a version with a built-in Lightning cable here at Amazon.
