What's in the box
The Jackery Giant Plus Powerbank was delivered in a nice cardboard box. In addition to the orange power bank, the package included a USB charging cable in black, an operating manual in English, a warranty card and a thank you note card.
Optics and functions
The Jackery Giant Plus Powerbank measures 11cm x 8cm x 2.1cm and therefore has a rather above-average size, which means that the powerbank still fits well in a pocket, but problems can arise with a host pocket. In terms of weight, the power bank comes to 295g. The case has a striking, orange color and is made of brushed aluminum, with the top and bottom made of white hard plastic. The power bank has a power button, a USB port with 5V and 2.1A, another USB port with 5V and 1A, a micro USB socket for charging the Giant Plus and two small LEDs that can be used as a torch. There is also a blue charging indicator (3 charging bars) on the side, which shows the current battery status of the power bank.
The flashlight can be switched on and off again by pressing the power button twice. The LED used here is not the brightest in terms of luminosity, but is sufficient to illuminate something in the dark.
As a nice feature, there is also a Jackery App, which is also referred to the Thanksgiving card. However, this app is only available for iOS and is just a battery management app for the smartphone. The app has nothing to do with the actual power bank.
High quality manufacturing
Quickly charged
High capacity
No inherent heat when charging
Bulky
Flashlight a little weak
The Jackery Giant Plus Power Bank is very well made and visually I find the orange design extremely appealing. Although the Giant Plus is not quite as portable as the smaller model with 9000mAh, but the Giant + comes on whole 12000mAh, making it ideal for longer trips, where you do not have a power source every day. I myself will use the power bank for festivals where a charge of the Jackery Giant Plus will surely power my smartphone for 3 days. Thanks to the high output current of 2.1A, I was able to fully charge my Nexus 5 within an hour. Overall, I was able to fully charge my Nexus 5 (2300mAh) with the 4x powerbank. Charging time to fully charge the power bank is about 6 hours.
The flashlight is a nice additional feature and certainly useful in an emergency. Unfortunately, I do not know which batteries were installed in the Giant Plus. However, it can be assumed that Jackery also used high quality batteries for the Giant Plus. The model with 9000mAh, for example, has Panasonic batteries.
Especially in comparison to cheaper power banks, I noticed that the Jackery Powerbank does not develop any heat of its own when charging a device and hardly gets warm when charging the Powerbank itself. Overall, the Jackery Powerbank fully lived up to my expectations and I can recommend it without any problems.
