256Wh Power Bank Capacity Test - Cheap "Solar Generator"

Introduction

In a recent video, I reviewed an inexpensive power bank that claims to have a capacity of 256 watt-hours. To verify this claim, I decided to set up a straightforward test to measure its performance. Using a time-lapse video, I tracked the power draw from a small crockpot and recorded the watt-hours consumed.

The setup was designed to provide a clear view of the power meter as it measured the energy consumed by the appliance over time. As the time-lapse progressed, it was evident that the watt-hours were steadily climbing, showcasing the power bank's performance in real-time.

After conducting the test, I found that the power bank provided approximately 2 hours of runtime when connected to a 100-watt appliance. The total energy consumption was just under 200 watt-hours. While this result did not meet the bank's claimed capacity of 256 watt-hours, I was still pleasantly surprised by the performance. It’s important to keep in mind that there are always losses when converting energy from batteries to AC power, which can account for some of the difference observed.
