Qi vs Qi2 vs MagSafe - Ultimate Wireless Charging Test!

Summary

In this video script, the presenter compares different iPhone chargers, including the official Apple charger, the new ch2, and a cheaper third-party option. The test evaluates charging speeds, wattage, temperature, and overall performance. The ch2 charger, priced at $22, demonstrates impressive 15W charging capabilities and faster charging times compared to the 7.5W chargers, despite heating the phone more. The official Apple charger is found to have the lowest heat generation, but at a higher cost. The conclusion suggests that for efficiency and speed, the ch2 is a valuable option, while the Apple charger remains a preferred choice for heat management.

Takeaways

• 🔋 The new ch2 charger offers the same 15W charging capability as the official Apple charger but at a lower cost.
• 💡 The test compared charging speeds, wattage, and temperature of different chargers, including the official Apple charger, ch2, and a cheaper 7.5W option.
• 📈 The ch2 charger turned on the iPhones faster than the official Apple charger and significantly outperformed the 7.5W charger.
• 🔌 At 15 minutes, the ch2 charger charged 30% more than the original Chi, which only managed 2%.
• 🌡️ Both the 15W chargers (max safe and ch2) pulled over 18W, but ch2 maintained a faster charging rate at around 12W compared to max safe's 11W.
• 📊 The 7.5W charger had the slowest charging rate and was the last to reach 100% charge, taking 4 hours.
• 💰 The ch2 charger is priced at $22, which is a good deal considering its 15W charging capability and included 5ft cable.
• 📏 The max safe charger comes with a 3ft cable, while the cheaper 7.5W charger includes a 6ft cable with a tie.
• 🌟 The max safe charger was found to have the least heat generation overall, making it potentially better for the iPhone's battery health.
• 🔥 Contrary to expectations, faster charging (15W) was found to be better for battery health than a consistent 7.5W load, as long as charging is slowed down when the phone gets hot.

Q & A

What are the key differences between the official Apple charger, the new ch2 charger, and the 7.5W third-party chargers for iPhones?

The official Apple charger has a 7.5W charging capacity, while the new ch2 charger offers a faster 15W charging speed. Third-party 7.5W chargers are generally cheaper but slower. The ch2 charger also comes with a longer cable and a stronger magnet compared to Apple's charger.

How did the charging speeds of the 15W chargers compare in the initial test with completely dead iPhones?

The new ch2 charger turned on the iPhone in 2 minutes, while the official Apple charger took a minute and a half. The 7.5W charger took significantly longer, about 10 minutes, to turn on the phone.

What was the charge percentage of the iPhones after 15 minutes of charging with the different chargers?

The official Apple charger reached 10%, the ch2 charger charged 30% more at 13%, and the original chi charger only hit 2%.

How much power do the 15W chargers pull to achieve faster charging speeds?

Both the max safe and the chi2 chargers, which output 15W, pull just over 18 watts to achieve faster charging speeds.

What was the temperature difference observed among the chargers when used with iPhones?

The chi2 charger hit 38 Celsius, the max safe was at 35 Celsius, and the 7.5W charger peaked at 37 degrees Celsius. The max safe charger had the least heat overall.

What is the benefit of fast charging initially and then slowing down as the phone gets hot?

Fast charging initially followed by a slower charge when the phone gets hot appears to be better for the battery health compared to a consistent 7.5W load, as it charges the phone more quickly without causing excessive heat buildup.

How long did it take for the different chargers to charge the iPhones to 100%?

The ch2 charger and the official Apple charger both took 3 hours to charge the iPhones to 100%, while the 7.5W charger took 4 hours.

What are the implications of using a 7.5W charger for long charging sessions?

Using a 7.5W charger for long sessions results in slower charging times, more heat buildup in the phone, and potentially slower charging speeds as the phone tries to cool down.

What additional benefits does the official Apple charger offer over third-party chargers?

The official Apple charger is compatible with a variety of cheap stands and holders, which third-party chargers may not fit into. It also tends to generate less heat overall, which could be beneficial for the device's battery health.

What is the price difference between the official Apple charger and the new ch2 charger?

The official Apple charger costs $40, while the new ch2 charger is priced at $22, making it a more affordable option with faster charging capabilities.

What are the main considerations when choosing between the official Apple charger, the ch2 charger, and the 7.5W third-party chargers?

Factors to consider include charging speed, price, cable length, build quality, heat management, and compatibility with stands and holders. The ch2 charger offers a balance of speed, affordability, and functionality, while the official Apple charger provides the best heat management and compatibility.
