Review Summary

We like the size, lightweight, waterproof design and high power output of 15 and 20W for wireless and wired connections respectively. The magnetic mount presents a new flexible way to attach the phone and battery together to any ferromagnetic material.

Although the creators demonstrated the battery is “waterproof” by dropping into a container of water, we assumed the design intention was not a ruggedised casing for underwater diving, swimming or outdoor uses.

Most electrical devices are certified waterproof either by IP rating under IEC 60529 or WaterProof Mark under ISO 2281:1990. In addition, if the device is designed for outdoor uses, it should also consider other tests including mud water, jolt, vibration and drop tests.

The size and weight are small and light, however, it is on par with other portable batteries which is bigger and heavier by almost two times. However, those batteries have 10,000 mAh capacity. There is no winner or loser in terms of design but users get to pick a smaller or larger battery pack depending on their needs. Mag Safer’s advantage i

Other Alternatives

The closest competition is the Techsmarter 10,000mAh, which is an outdoor battery pack with a wireless output of 10W that is much lower  when compared to Magsafer’s 15W. However, the USB-C charging supports 18W PD charging.

It also weighs almost double at 260 grams, which is expected since the battery capacity of 10,000mAh is double the 5,000mAh of the Magsafer 2.0. It also has a certified IP67 rating for water and dust protection, and is also shockproof based on the rounded corners of the casing. Considering that these environmental design, the weight of 260 grams is very impressive.

There are also emphasis on the safety design, which is important for electrical devices.
