Excellent value for money charger for 2+ full charges for most Android smartphones including S/Note/A series and four charges for small-screen iPhones such as iPhone 8, 7, 6s, and 6. However, it is a bit bulky and heavy, and takes very long (10 hours) to charge fully from empty.
As Jackery no longer offers small power banks but only the giant Jackery Power Station portable chargers now, we instead recommend the excellent and more modern ZMI Powerpack 10000 USB-C from ZMI/Xiaomi for fast-charging the latest iPhone 13/12/11 series from zero to 60% in 30 mins and Samsung S/Note/A series from zero to 50% in 30-40 mins. It charges iPhone 13/12 Pro/Pro Max etc. from 20% to 100% twice and Samsung S/Note/A from 40% to 100% twice.
What We Like
- Price! Good value for money
- Two 2.4 amp smart-charging fast charging ports
- Panasonic Li-Ion cells
- True 12000 mAH capacity
- Attractive eye-catching design
What We Do Not Like
- Bulky and heavy compared to high end power banks
- Takes 10+ hours to charge. No QuickCharge Input or Output feature
Jackery Giant+ 12000 Powerbank is a good value for money 12000 mAH charger good for charging iPhone 8, 7, 6s/6 about 4 times and Samsung Galaxy S10, S9 about 2.5 times.
The reasonable price and solid and reliable build quality with true 12000 battery capacity is the best selling point for this power bank. However, competing power banks from Anker and RAVPower offer features such as QuickCharge Input and dual fast/smart charging ports and this makes this otherwise excellent charger a good option only when you want a reliable 3-4 charge powerbank at lowest price.
Attractive Design
Jackery Giant+ 12000 Powerbank has a solid and eye-catching design that combines with the four attractive color options that make it stand out. The orange option is good for making this powerbank easy to spot among clutter. The powerbank is .8 inches thick and has dimensions of 4.3 inches by 3.1 inches. Outer shell is brushed aluminum and it is easily one of the best looking p[ower banks out there.
The thickness and dimensions are same as other competing powerbanks in this category.
The 10.9 oz weight is a bit on higher side for 12000 mAH charger as 13400 mAH powerbanks of Anker and RAVpower weigh about the same. The powerbank also has a built-in LED flashlight.
Good Overall Charging Performance
Jackery Giant+ 12000 Power bank has two charging ports. Both ports offer 2.4 Amp fast output that will charge smartphones/tablets in half time than standard port. The ports will also charge the iPad at 2 Amp current.
However, this port configuration is equal in speed to the 2.4 + 2.1 Amp dual charging ports offered by the RAVPower 10000 or 2.4 + 2.4 Amp dual charging ports offered by Anker PowerCore 13000. Both these portable chargers are also among our list of best portable chargers that you can buy.
Jackery Giant+ 12000 Powerbank charges an iPhone 8, 7, 6, 6s about 4 times and a Samsung Galaxy S10, S9, S8 about 2.5 times after a full charge.
The powerbank itself gets charged to full charge from zero in about 10 hours by a 2A wall charger and about 16-18 hours by a 1 Amp charger. Lack of QuickCharge or dual smart-charging ports is a big missing thing.

The Competition is Much Ahead
Jackery Giant+ competes with the excellent RAVPower 10000 external battery bank and the QuickCharge 2.0 Input Anker PowerCore 13000 portable charger. Both of them are far superior powerbanks than Jackery Giant+ 12000 as they give higher battery capacity and features.
RAVPower 10000 is our clear recommended powerbank in this range as it offers dual 2.4 + 2.1 Amp smart ports (4.5 Amp total) at an incredible price point. RAVPower 10000 boasts off all the good point of Jackery and then delivers the added benefit of dual smart ports at an unbeatable price point.
Anker PowerCore 13000 is our next favourite powerbank in this range. It offers category best dual 2.4 Amp fast charging ports (total 4.8 Amp) and has the added benefit of Quick charge 2 input which allows you to charge the powerbank in about 5 hours flat using a QuickCharge wall charger. Please note that Anker PowerCore+ 13400 does not come with Quickcharge Output just input. It however has best-in-class dual 2.4 Amp fast charging ports.
Overall, despite being a good quality true-capacity charger, we will not recommend Jackery Giant+ 12000 as RAVPower 10000 and Anker PowerCore 13000 – both deliver better features and battery capacity at same weight.
