Quick answer: the Jackery Explorer 100D is Jackery's smallest power station yet: 96 watt-hours of LFP battery, 158 watts of output, and a body close to the size of a soda can, announced November 2 at $119. It is built for laptops, phones, cameras, and carry-on travel. It is not built for house backup, and if that is what you were hoping for, the numbers below will save you the return shipping.
What the Jackery Explorer 100D actually is
The Explorer 100D sits at the very bottom of Jackery's Explorer line, one notch under the Explorer 100 Plus we covered last year. It is a DC-only battery pack: no AC inverter, no wall outlets, just USB ports in a palm-size shell. The battery is lithium iron phosphate (LFP), which Jackery rates for 3,000 cycles before dropping to 80% capacity and claims an 8-year lifespan. That chemistry is the same long-life type Jackery now uses across the line, and it is the main reason a small pack like this can be a buy-once item instead of a two-year disposable.
The physical specs are the story here. Roughly 1.9 lb (Jackery lists 965 g on its product page, most coverage measured 850 g bare), 4.6 by 3.4 by 3.4 inches. It genuinely fits in one hand and vanishes into a backpack side pocket. For comparison, the Explorer 300 weighs about three times as much and the smallest real backup tier, the Explorer 1000 v2 class, starts near 25 lb.
Ports, charging speed, and the small display
You get two USB-C ports and one USB-A. The C1 port handles up to 140W in either direction, which means it can charge a 16-inch MacBook Pro at full speed and also refill the station itself from a 140W wall adapter. The USB-A port tops out at 18W. All three ports running together draw a combined 158W. There is a small display showing per-port output, battery health, cycle count, and temperature; double-press the button and it goes dark.
Charging works three ways: a 140W wall adapter through C1, a 100W solar panel, or a 100W car socket. Any of the three takes the Explorer 100D from empty to 80% in about 1.7 hours. That is quick for this class, and the solar option means it can top itself off on a camping table while it runs a camera or a drone battery.
Two details worth knowing. The pack supports AVS charging (Adjustable Voltage Supply), which negotiates precise voltages for Apple gear instead of stepped profiles. And a 3-second hold on the display button drops it into low-power mode for earbuds, watches, and other small loads that trick bigger stations into auto-shutdown.
Can you fly with the Explorer 100D?
Yes, with a caveat. US FAA rules and most international equivalents allow lithium batteries up to 100Wh in carry-on baggage, and the Explorer 100D's 96Wh sits just under that line. That placement is deliberate; anything bigger would need airline approval. Keep it in your carry-on, not checked luggage, and check your specific carrier's policy since a few airlines are stricter than the baseline rule.
Where it fits in a house outage plan (and where it does not)
Be clear-eyed about the math. A modern phone takes roughly 15Wh for a full charge, so the 96Wh inside the Explorer 100D is about six phone charges, or a router and a tablet through a long evening. That is genuinely useful during a short blink, and the fact that it holds a charge for months makes it a fair grab-bag item.
What it will not do is run anything with a plug. No AC inverter means no refrigerator, no furnace fan, no sump pump, no CPAP. Those jobs start around the 1,000Wh class, and the honest move is to check your actual loads in our generator size calculator before spending anything. If outages in your state tend to run long, the practical tier jump is straight to the Explorer 1000 v2 class or a gas portable, not stacking small DC packs.

How it compares: 100D, Explorer 100 Plus, and Anker's C200 DC
The closest rival is Anker's Solix C200 DC: 192Wh (twice the capacity) at roughly $30 more. On paper that makes the Anker the better value per watt-hour. The Jackery counters with size and weight; it is meaningfully smaller and lighter, and Jackery's charge-speed edge (1.7 hours to 80%) closes some of the daily-usability gap.
Against its own sibling, the Explorer 100 Plus carries a bit more capacity in a similar pocket format. If you already own any 100-class pack, the 100D is not an upgrade, it is a sidegrade for people who want the newest, smallest option. The full Jackery Explorer lineup compared lays out every current model side by side.
You can check current availability through Amazon search; at announcement the 100D was in a pre-order signup phase on Jackery's own site, so third-party listings may lag by a few weeks.
Who should skip it
Anyone who needs AC outlets. The DC-only design is the whole point of the size, but it also draws a hard line: if your emergency kit needs to run anything with a plug, this is the wrong product. Likewise, if you already own a 100-class power station, there is no functional reason to switch. And heavy users who drain a pack daily might prefer the Anker's doubled capacity over the Jackery's smaller frame.
FAQ
Is the Jackery Explorer 100D allowed on flights? Yes in carry-on. Its 96Wh capacity sits under the 100Wh limit most aviation rules set for lithium batteries without airline approval. Checked baggage is not permitted for spare batteries, so keep it with you in the cabin.
Can it charge a laptop at full speed? Yes. The C1 USB-C port supports up to 140W output with AVS negotiation, enough for a 16-inch MacBook Pro at or near its maximum charging rate.
Can the Explorer 100D run a refrigerator or CPAP during an outage? No. It has no AC inverter and only 96Wh of capacity. Refrigeration and medical gear start in the 1,000Wh class; use a generator sizing calculator before buying anything for those loads.
How long does it take to recharge? About 1.7 hours from empty to 80% using a 140W USB-C adapter, a 100W solar panel, or a 100W car charger.
Bottom line
The Jackery Explorer 100D is a travel-first battery: $119 buys the smallest competent 140W charging brick-plus-battery on the market, an LFP cell that should outlast the devices it charges, and a clean fit under the 100Wh flight line. As a house backup tool it is honest about being tier one, phones and tablets only. Buy it for the carry-on, keep a bigger station or a generator for the outage list, and the two jobs never have to fight over one battery.
