Jackery's New Explorer 100D Slips Under Airline Carry-On Limits

Jackery has added its smallest power station yet to the lineup. The Explorer 100D packs a 96 Wh LFP battery into a case roughly the size of a softball, keeping it just under the 100 Wh ceiling most airlines use for carry-on batteries.

That positioning is the whole pitch. It’s bigger than a phone power bank, smaller than a solar generator, and light enough at 1.87 lbs (850 g) to toss in a backpack without thinking twice.

Key Specs: 96 Wh (30,000 mAh) capacity · 158 W max output · 140 W USB-C input · 3,000 full charge cycles · 1.87 lbs

Ports, protocols and what it actually powers

The front panel carries two 140 W USB-C ports and an 18 W USB-A port. One USB-C handles both input and output, and the unit can discharge through the other two ports while it’s recharging — a small thing that turns out to be genuinely useful.

Protocol support covers AVS, PD 3.1 and PPS, which means precise power delivery to Apple hardware in particular. No wall charger ships in the box, just a USB-C cable.

In hands-on testing the 100D ran a Wi-Fi router for a full day with room left over for a phone and tablet. A 5 W personal fan barely registered. On Halloween it kept a Bluetooth speaker going for hours while topping up phones, and still finished the night above 90%.

Solar input tops out at 100 W through the USB-C port, so the folding SolarSaga 100 Air can refill it in under two hours. It also accepts 12 V or 24 V from a car, boat or RV.

LFP chemistry and the long-game math

There are no cooling fans or vents here, unlike Jackery’s bigger units. The lithium iron phosphate cell is rated for 3,000 full charge cycles — roughly eight years of daily use, and a 50% jump over the Explorer 100 Plus it replaces. That headroom matters because most Li-ion power banks tap out after a few hundred cycles.

The new model is also smaller and lighter than the 100 Plus while pushing more output. A cloth handle comes standard, and there’s an optional shoulder strap.

One wrinkle for travellers heading to China: the test unit carried FCC and SGS markings but not the CCC logo, despite meeting the standard. Without that stamp printed on the case, the battery could be confiscated at Chinese checkpoints. Jackery may address this on later production runs.

Price and availability

• Costco bundle: Two units for $179.99, at select warehouse locations from early November 2026
• Walmart single unit: $99, available from November 15

That timing lands neatly ahead of the holiday travel rush.

Jackery was recently named the world’s top solar generator brand by Frost & Sullivan, and the 100D slots into a product range that already stretches from pocket-sized packs to home backup systems. Steven Wang, CEO of Jackery Americas, framed the launch around portability plus compatibility: the company’s argument is that long lifespan and broad device support matter more than raw watt-hours in this size class.

A $99 price for a 3,000-cycle LFP pack is aggressive. Whether it holds up over months of real travel is the open question — and one worth watching.
