32 Powerbanks im Kapazitäts-Test! Alle fallen durch!

In this video, I'll show you how 32 power banks performed in a real-world performance test – and why not a single one reached its promised capacity. You'll learn how to correctly measure power banks, what to look for when buying one, and how to properly file a complaint if the performance isn't as advertised. I'll also explain step by step why mWh is more important than mAh and how you can conduct your own fair, reproducible tests. If you want to know: • how to properly test power banks, • how significant the discrepancies really are, • and how I ultimately got all 32 power banks refunded, then this video is for you. And maybe you'll even get a free power bank or two by conducting your own tests! Please excuse my hoarse voice. I have a bit of a cold! ``` 🔧 Tools used (insert links): USB tester: https://amzn.to/4poGFXQ USB load resistor: https://amzn.to/49j1cXW Combination device (USB tester & USB load resistor): https://amzn.to/4pqW4XI ECOFLOW River 2 Max (I used this for free charging with solar power): https://amzn.to/4pqW4XI 200W solar panel: https://amzn.to/4phDZeU 📊 Ranking of all 32 tested power banks (Rank 1 → 32): Rank 1: https://amzn.to/42nwMSg Rank 2: https://amzn.to/3SrbjBP Rank 3: https://amzn.to/4mBqO7D Rank 4: https://amzn.to/46Jasom Rank 5: https://amzn.to/3J1bGlm 6th place: https://amzn.to/46FGUYE 7th place: https://amzn.to/42mvNjT 8th place: https://amzn.to/3E8YhFG 9th place: https://amzn.to/4jenFZb 10th place: https://amzn.to/3EqvOLP 11th place: https://amzn.to/4nwPUoP 12th place: https://amzn.to/4nT7bZP 13th place: https://amzn.to/42pfQe9 14th place: https://amzn.to/4jGg86k 15th place: https://amzn.to/4lcVquU 16th place: https://amzn.to/3Hm1pzB 17th place: https://amzn.to/4iOaQEB Rank 18: https://amzn.to/4o7EXKm Rank 19: https://amzn.to/3RrMUvD Rank 20: https://amzn.to/3RAdcfb Rank 21: https://amzn.to/4iOBPjo Rank 22: https://amzn.to/4ssUo2D Rank 23: https://amzn.to/4iZKBLF Rank 24: no longer available Rank 25: https://amzn.to/4mbK1NH Rank 26: https://amzn.to/4353WFf Rank 27: https://amzn.to/4jmTxve Rank 28: https://amzn.to/4jqYpkf Rank 29: https://amzn.to/4o7EXKm Rank 30th place: https://amzn.to/4kkg4cB 31st place: https://amzn.to/3IZyHW4 32nd place: https://amzn.to/42RO1v0 🛠️ Transparency notice: I purchased all power banks and measuring devices myself.
