Kmashi Arma 3-in-1 battery flashlight charger ReviewFebruary 18, 2016
- Outstanding impact resistance
- Integrated LED flashlight
- Integrated bluetooth speakers
- Low overall battery life
- Low power to size ratio
- Quality/reliability issues
The Kmashi Arma 3-in-1 is a flashlight, bluetooth speaker, and portable charger all rolled into one. It’s extremely durable and weathered our impact tests well. However, the product line may have build quality issues: our first sample failed to deliver power at all, and the speakers in our second sample shorted out during water resistance tests (despite the device’s ‘waterproof’ claims). Still, Kmashi was responsive with replacements. For those in the market for a single device that combines a flashlight, bluetooth speaker, and portable charger, the Arma 3-in-1 may be a good fit.
The device we were initially given for these tests did not work properly, and failed to deliver any power. The replacement device did not have the same issues, but still had low overall battery compared to competitors: delivering only 170 minutes of power in our intensive ‘real world’ tests. Among mid-size devices tested, the Kmashi 3-in-1 placed last. Discharge rate was also 25% slower than the industry average.
Like battery life, the Kmashi 3-in-1’s power to size and power to weight ratios were also low, and ranked last among all mid-size portable chargers tested.
In terms of impact and compression stress, the Kmashi 3-in-1 ranked amongst the highest devices we tested, regardless of size or category. The Kmashi 3-in-1 sports a solid metal housing that is surrounded by thick, durable rubber. Though the Kmashi 3-in-1 advertises itself as being waterproof, the speaker shorted during our water resistance tests.
The Kmashi 3-in-1 offers standard 1 amp USB ports and integrated power level indicators, an integrated LED flashlight, and integrated bluetooth speakers.
In terms of battery life and power per dollar spent, the Kmashi 3-in-1 delivers average scores.
