Zilu SafePower S5 smart battery pack ReviewJuly 22, 2016
- Good battery life
- Excellent power-per-ounce
- Average durability
The Zilu SafePower S5 is a great all-around portable charger. It isn’t at the top of the class in battery life or power:size ratios, but it does both well, and at a great price point. Durability is average, but with no major obvious issues. Overall, the Zilu is an excellent buy.
The SafePower S5 delivered over 703 minutes of power in our intensive ‘real world’ tests, earning fourth place among all large-size chargers tested. Discharge rates were also good, and on par with category averages.
The SafePower S5 also scores well for power:size and power:weight ratios, earning fourth place among large size chargers for power-per-cubic inch, and third place for power-per-ounce.
Durability for the Zilu SafePower S5 is average but not outstanding. The battery is housed in a plastic casing that is solid and with no obvious design issues. The SafePower S5 weathered impact tests better than some competitors, but did not perform as well as more durable devices. Overall, durability is good, and the SafePower S5 would be an excellent choice for general/everyday use and leisure travel.
The Zilu SafePower S5 sports integrated 1 and 2.1 amp USB ports, power level indicators, and a small LED flashlight.
In terms of value, the SafePower S5 scores very well, placing third among all large-size chargers tested, and third among all devices tested, regardless of size or category.
