Portable Charger from Tesla Explained

Tesla, a brand synonymous with cutting-edge electric vehicle innovation, has made notable advancements in personal charging accessories. In 2021, the company introduced its first wireless charger, which came with a fixed cable. More recently, Tesla launched a refined and compact wireless portable charger designed to blend premium aesthetics with practical usability. This new portable charger Tesla edition has quickly caught the attention of tech enthusiasts and Tesla owners alike, not just for its design but for its performance as well.

Sleek Packaging and Unboxing Experience

The wireless portable charger Tesla comes in a sleek black packaging box, with the product name clearly printed on the top. On the bottom, detailed specifications are listed. Inside the box, you will find the charger and some basic documentation. The charger itself is made of plastic and coated with metallic paint, giving it a premium finish. Its edges are sharp and modern, aligning well with Tesla’s minimalist design language.

The front panel, which serves as the wireless charging surface, features the iconic ‘Tesla logo‘. The charger uses a flip-top design that can double as a smartphone holder. When opened, it allows you to attach your phone in either vertical or horizontal orientation for charging, and the phone remains stable during the process. The interior surface of the charging panel is lined with Alcantara suede, enhancing grip and preventing scratches.

Technical Specifications and Charging Capabilities

This Tesla wireless portable charger is identified by the model number TSL02. It houses a 5000 mAh battery with a total energy rating of 19.3 watt-hours. The device supports input voltages of 5 volts at 2.4 amps, 9 volts at 2 amps, and 12 volts at 1.5 amps. The maximum output through wired charging is 20 watts, while the wireless charging output reaches up to 15 watts, with a secondary standard wireless output level of 5 watts. The maximum power supported by the wireless receiver is 10 watts.

An integrated USB-C cable, approximately 10 centimeters in length, allows for wired charging and data transmission. The charger also features a USB-C port that can serve both input and output purposes, depending on how the device is being used. A power button located on the top surface activates four LED indicators, which display the current battery level. In terms of size, the unit measures approximately 101 by 70 by 17 millimeters and weighs about 189 grams, making it light and easy to carry.

Broad Protocol Support and Compatibility Testing

The built-in USB-C cable and port support a wide range of modern charging protocols. These include QC 3.0, FCP, SCP, AFC, PD 3.0, DCP, and Apple 2.4 amp standards. The charger also offers three fixed power profiles at 5 volts 2.4 amps, 9 volts 2.22 amps, and 12 volts 1.67 amps. This makes the device highly compatible with a wide range of smartphones, tablets, game consoles, and even smaller laptops.

During real-world compatibility testing, the charger performed well across various devices. Most modern smartphones were able to reach charging speeds of around 9 volts. Larger devices such as tablets and gaming consoles drew power at up to 12 volts. When charging two devices simultaneously or using the wired and wireless functions together, the voltage output automatically drops to 5 volts for safety and to prevent overheating.

The charger also supports wireless input charging, although it does not feature magnetic MagSafe alignment. However, when tested with a MagSafe charger at 75% battery, the device achieved charging speeds between 7 and 8 watts. This makes it especially convenient for Tesla owners, who can place the charger in the car’s center console charging station for wireless charging.

Charging Performance and Efficiency Testing

We used an Apple 35-watt charger to test how long it takes to fully charge the Tesla wireless portable charger. The test was conducted inside a thermal tank set at 25 degrees Celsius. The charging curve, recorded using PC software linked to the KM003C charger monitor, revealed a consistent voltage of around 9 volts.

Dual-Phase Charging Behavior

The charging process is split into two phases—an initial 47-minute high-power phase at 18W, followed by a gradual power reduction to protect the battery as it nears full charge.

Efficient Charge Progression

The charger swiftly reached 50% in 36 minutes and 80% in about 1 hour and 2 minutes, ultimately completing a full charge in 2 hours and 8 minutes, reflecting a well-balanced speed and safety strategy.

Efficiency was also tested at various output levels. At 5 volts 2.4 amps, the device outputted energy for 16 minutes, releasing about 3.47 watt-hours. On 9 volts 2.2 amps, output lasted 5 minutes with 1.67 watt-hours released. At the maximum of 12 volts 1.67 amps, the output ended in 4 minutes with 1.36 watt-hours delivered. These results suggest that while peak power is available for short durations, the charger is optimized for moderate, efficient use.

Ripple and Temperature Performance

Ripple testing showed promising results, both without and with load. At 5 volts without load, the ripple was around 15.6 millivolts peak-to-peak, while at 12 volts, it reached up to 19.2 millivolts. Under load, ripple peaked at 27.6 millivolts at 12 volts 1.67 amps and dropped to 12 millivolts at 5 volts 2.4 amps. This low ripple ensures safe, stable charging, reducing the risk of damage to connected devices.

The charger was then tested for thermal performance under load conditions. With the charger inside a 25-degree Celsius thermal tank and outputting 20 watts at 12 volts 1.67 amps, the maximum temperature recorded on the front panel was 32.1 degrees Celsius. The back panel peaked at 39.6 degrees Celsius, with the highest temperature observed near the charging port. While it felt warm to the touch, the heat levels remained well within safe operating limits.
