Jackery Explorer 100 Review UK 2026
Quick verdict
Score: 8.3/10
Best for: Phones, laptops and light camping use
Not for: Running fridges or power tools
Bottom line: A practical portable power station with 99Wh capacity and long-life LiFePO4 cells, best matched to the device wattages and runtime you actually need.
The Jackery Explorer 100 (JE-100A) is a small 99Wh power bank for portable charging, with a stated rated output of 128W and up-to 100W solar input. The quick verdict is that it suits travellers needing compact backup power, about 0.96kg in a palm-sized case, and a TFT status screen. It can charge via wall using fast dual PD 3.0, and via solar using a 100W panel, though the actual recharge time depends on sunlight; for many users, it is worth it when weight and quick top-ups matter.

Capacity and What It Powers
With a 99Wh capacity in this portable power station (JE-100A), this portable power bank is built for small electronics rather than heavy appliances. Its maximum rated output is 128W, which suits short, reliable charging bursts for devices such as phones and tablets. Manufacturer claims state it can fully charge a Phone 6 times and a tablet twice. With a limited capacity, higher-draw devices may drain it faster than expected, so lighter loads match its intended use.
Output and Ports
Output and ports on the Jackery (JE-100A) centre on charging rather than powering power-hungry appliances. The rated output reaches 128W, so it is suited to recharging small electronics rather than running larger loads. The unit includes two USB-C ports and one USB-A port, supporting charging three devices at once. It also supports PD, AFC, QC, and PPS protocols, helping compatibility across a wider range of chargers. For sustained use with bigger devices, the output limits are reflected in the portable power station pros and cons.
Recharging and Solar
Recharging the Jackery (JE-100A) is about how quickly its 99Wh battery can refill using either wall power or solar, with the charging speed depending on the chosen method. For the portable power station, wall charging uses 100W dual PD 3.0, supporting up to 70% in 1 hour and a full recharge in 1.8 hours. Solar charging uses the Jackery Explorer 100 solar generator approach, paired with a 1 SolarSaga 100W panel, reaching 0 - 70% in 1 hour and full in 2 hours. Actual charging time can vary with sun strength, clouds, and panel placement.
Battery Type and Lifespan
The Jackery (JE-100A) uses a LiFePO4 lithium iron phosphate battery. This chemistry is selected for long life and durability, and in the portable power station market it is positioned around a cycle-focused lifespan with a typical rating of 3,000+ cycles. The manufacturer also states the battery can retain about 80% capacity after 2,000 cycles, which is relevant for repeated daily use. LiFePO4 cells are generally more tolerant than some alternative lithium chemistries, but actual outcomes depend on charging habits and temperature, so lifespan still hinges on proper charging.
Portability and Build
Portability is central to the expected use of a small power bank, and the Jackery (JE-100A) is built around that goal. At about 0.96 kilograms and palm-sized dimensions (9 x 9 x 13 cm), it is easier to carry than larger units, including on trips and commutes. The manufacturer also says it meets aviation carrying standards, which can help with travel planning. Build is compact and simple on these points. For buyers comparing the portable power station price, weight and size are the clearest portability indicators.
Who Is This Power Station For?
For whom does this portable power station (JE-100A) make the most sense? It suits travellers who want a portable power station for camping, particularly for powering phones, tablets and small devices, thanks to its 99Wh capacity and up to 128W rated output. It is also a practical choice for short trips and light emergency backup, since it supports multiple charging protocols and can charge up to three devices at once. People asking if the Jackery is any good should note it is 0.96 kg, palm-sized, and recharges in about 2 hours via wall or solar.
Where to Buy in the UK
Finding the right place to buy the Jackery Explorer 100 (JE-100A) in the UK mainly comes down to the intended use, since it is built for compact charging rather than running larger equipment for long periods. Many buyers compare Amazon UK listings for clear spec details such as 99Wh capacity and 128W rated output. Shoppers also look at The portable power station "cheapest" options during seasonal discounts, though stock and bundle contents can change. Outside of marketplaces, it may be available from retailers including Currys and Argos, but availability is inconsistent. Before buying, confirm the included cables, the 2-year warranty, and UK plug support (not stated).
Frequently Asked Questions
What can this portable power station power?
With 99Wh capacity and 128W rated output, The Jackery suits phones, laptops, lights and small devices. Match the device wattage to the station's rated output before relying on it.
How long will the portable power station last?
Roughly, runtime = 99Wh minus around 10-15% conversion loss, divided by the device's watts. A 60W device on this station runs for several hours; a high-watt appliance drains it far faster.
Can you recharge the Jackery with solar?
Yes - The portable power station accepts up to 100W solar input from a compatible panel (usually sold separately), which is what makes it a "solar generator" for off-grid and power cuts.
What battery does the Jackery Explorer 100 use and how long will it last?
This portable power station uses a LiFePO4 battery (long lifespan, 3000+ cycles typical). LiFePO4 cells typically keep 80% capacity after 3000+ charge cycles - roughly ten years of regular use - and are safer and more stable than older lithium-ion.
Is the Jackery good for power cuts and camping?
The portable power station is well suited to camping, caravans and as backup during power cuts, and it recharges in about 2 hours. For whole-home backup you would need a far larger unit and proper switchover, so treat it as essentials backup.
Is the Jackery worth it?
If you camp, face power cuts, or want quiet portable power, the portable power station earns its place for its 99Wh capacity. Check the current Amazon UK price, as power stations are heavily discounted around Prime Day and Black Friday.
