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 to any ferromagnetic material.

Although the creators demonstrated the battery is “waterproof” by dropping it 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 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.

The size and weight are small and light. However, it is on par with other portable batteries, which are bigger and heavier by almost two times. However, those batteries have a 10,000 mAh capacity. There is no winner or loser in 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, an outdoor battery pack with a wireless output of 10W that is much lower when compared to Magsafer’s 15W. However, USB-C charging supports 18W PD charging.

It also weighs almost double 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 these environmental design, the weight of 260 grams is awe-inspiring.

There is also an emphasis on safety design, which is essential for electrical devices.
