![]() All fans were tested with Radioshack batteries and the mean was taken of fan/battery duration (leaving the most accurate fan tests to be for Radioshack and Duracell ProCell). If we needed to change fans during a test, that battery received an additional test on that second fan. We tested each battery on a single fan (where possible) three times. Once we removed those fans from the data, we had a 15.7% deviation in fan workings – which was, sadly, pretty high. From there, we tested the fans similarly but discovered a 25% deviation – mainly from two fans being clearly defective. Trials were performed at both 58✯ and 68✯. We used the Duracell ProCell batteries to test the SD of the Saramonic Transmitters and established a 4.2% SD between them after 12 trials. We recorded all tests on our Canon C100 and logged timings to the second. It also dramatically shortened our testing period and allowed us to test many more batteries at a go. We also tested the multiplier between transmitter and fan current draw which came to the fan battery life being on average 4.24 X shorter than the UWmic9s, which was favorable, since it more accurately simulated a “high transmitter wattage” setting which the UWmic9s possess as an option as do the Sony UWP systems and several others. The UWmic9s were set to medium power transmission and the accompanying lavalier microphones were plugged in and activated (increasing the battery load). We created a series of tests to quantify a standard deviation (SD) with the wireless transmitters we used ( the Saramonic UWmic9 Transmitters), then take that data and apply it to the general testing mechanism: 14 personal cooling fans. Little did we know how narrow the results would be in the final analysis – yet how important it would be to be as rigorous as possible to garner detailed results. In other words, we didn’t want to spend 2 months and have our wireless transmitters tied up to do this test – while making it as accurate as possible. While we’re certainly not a laboratory-level testing facility, we decided to try our best to narrow the standard deviation of the trials as much as possible – while still making the tests reasonable. Saramonic UW-Mic9 Transmitters were used on the Medium power setting, along with personal fans for semi-finals. We used the ProCell batteries as our standard 1X ratio from which every other battery would be measured, since it’s the battery we’ve been using for years. With these parameters, we chose the following brands and types: ACDELCO
