Hello everyone!

After posting some Input and Output Comparisons almost a month ago, I got the chance to write a detailed review for a German Tech Outlet called "Smartzone".

You can find my full review here -> Link

The review is of course in German, but can naturally be quickly translated into the language of your choice with today's tools. I have tried to appeal to both casuals and professionals in the review and hope that you can take something interesting and informative away from it.

If there is something specific missing or not answered, feel free to leave a comment and I try my best to answer it.

Here is my tl;dr: Excellent Powerbanks and easily Top 3 in its field. Fantastic net capacity, high sustained performance, quick input, good App-Support, really nice weight and size for the power etc. It only has two issues:

1: The price - it's just really, really expensive.
2: it should be the best with that price tag, but that's sadly not the case. The older Anker Prime 250W model is still better. Despite the lower numbers it charges even quicker and can sustain highest output even longer. The 300W model makes a fair trade off: it's lighter and slimmer as the 250W one, but not quite as powerful, gets hotter and throttles quicker in comparison to the old model. Check the comparisons I posted above! If you really want the best of the best, grab the old model. But if you also value less size and less weight and also don't mind the high price tag, you can not go wrong with the new model. Choice is up to you. Check your use case first!
(2.5: The old 250W one had SuperVOOC (for OnePlus, Oppo, Realme) with up to 65W on the USB-A, the 300W does not support SuperVOOC anymore).

You can find all the collected data from this review and much more (Powerbanks, Chargers, Charging Times, etc) in my Google Sheet

I post new reviews, deals and other stuff related to Charging in my Sub called Charging Sheet

Im wondering, does this power bank use silicon carbon batteries? The body profile is much smaller than my Anker 737 or Cuktech 20. The packaging and unboxing for this are really nice.
