Wisdom 3A Plus vs Wisdom 4A: What Is the Difference?
Share
If you are choosing between the Wisdom 3A Plus and the Wisdom 4A, the decision is simple.
The only difference is that the Wisdom 4A includes a power-bank function for charging compatible USB devices. Their lighting performance is otherwise the same.

The one practical difference: power-bank functionality
The Wisdom 4A has a 7,000 mAh lithium-ion battery and a power-bank function that can supply power to compatible USB devices. This can provide a useful backup charging option when working or travelling away from a standard power outlet.
This feature does not give the Wisdom 4A greater light output, beam distance or lighting runtime. Those figures are the same as the Wisdom 3A Plus.
Why choose the Wisdom 3A Plus?
Choose the Wisdom 3A Plus when you want the same lamp performance and do not need USB device charging. It is the straightforward choice for customers who require a cordless cap lamp without the additional power-bank feature.
Why choose the Wisdom 4A?
Choose the Wisdom 4A when you want the same lighting performance plus the flexibility to charge a compatible USB device from the lamp. The 4A is the better choice only when that extra function is useful to you.
Which model is right for you?
Your choice comes down to one question: do you need the power-bank function?
- No: choose the Wisdom 3A Plus.
- Yes: choose the Wisdom 4A.
