If you are a hiker or solo camper, this Jackery Explorer 300 Plus review is exactly what you need. The original Jackery 300 was a legend, but it had an old battery. The new “Plus” version changes everything.
It finally brings LiFePO4 (LFP) technology to the smallest form factor. It fits in a backpack, weighs almost nothing, and promises 10 years of life.
But with faster rivals like EcoFlow, is Jackery still the king of portability? In this 2026 test, we find out.
1. Design & Portability: The “Backpack” Battery
The biggest selling point of this unit is its size. It is incredibly compact.
- Weight: Only 8.27 lbs (3.75 kg).
- Handle: Foldable (unlike the old fixed handle), making it easy to stack.
- Build: Classic rugged Jackery orange/grey, feels solid enough to take a drop.
2. The Major Upgrade: LFP Battery
This is why you buy the “Plus” version.
- Old Jackery 300: Lithium-ion (500 cycles).
- New 300 Plus: LiFePO4 (3000+ cycles).
- Verdict: This unit is an investment. It will last for over a decade of daily use without losing significant capacity.
