Specifications
Last checked on 10 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 288 Wh (22.5 Ah at 12.8 V) |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 (LFP) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | The specification table says 3,000 cycles to 80% or more of capacity. The FAQ on the same page says it is rated for 1,500 full charge cycles to about 80%. |
| ExpansionExtra battery units that add storage to the same system. | Not stated for this model |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | 300 W rated, 1 AC outlet, 230 V, 50 Hz |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | 600 W peak |
| USB-APorts for phones, tablets and small devices. | 1 port, 15 W maximum |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 1 port, 100 W maximum |
| Car outletA 12 V socket like the one in a car, for car accessories. | 1 DC 12 V port, 10 A maximum |
| Pass-through chargingWhether it can power devices while it is itself being charged. | A bypass mode passes mains power through to the AC outlet, up to 300 W |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 220 to 240 V, 50 Hz, 10 A maximum. Charging wattage not stated. |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | 2 hours |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 100 W maximum, 12 to 27 V, 5 A |
| Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names. | 9.5 hours with one SolarSaga 40 W panel (specification table). The feature text says 4 hours with one SolarSaga 100 W and, in another line, with a 200 W panel. |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | 5.5 hours |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | Not stated |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 23 × 15.5 × 16.7 cm, as listed (the page does not say which side is which) |
| WeightMatters for lifting, wall mounting and moving it. | 3.75 kg |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Supplies power from -10 to 40 °C (solar panels -10 to 65 °C). Charging range not stated. |
| Noise levelFan noise while working. | Described as whisper quiet; no decibel figure stated |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 3 years standard plus 2 years extended (the page also advertises a 5-year warranty) |
How long will it run your devices?
Choose how many of each device you want to run at the same time. The wattages are typical figures, so check the label on your own devices.

The estimate assumes 85% of the rated capacity is usable after conversion losses. Jackery does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.

Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. Connecting one to your home circuits to power the house is different, and the rules for that vary by country. See our country guides for the rules, incentives and prices where you live.

Where this information comes from
We have not tested the Explorer 300 Plus. Every figure above comes from Jackery's UK product page, including its specification table and FAQ, last checked on 10 November 2026. The page gives different figures for cycle life and solar charging time in different places; we show both. A value the page does not state is shown as not stated.
We do not show prices, because they change often and differ between sellers.

Common questions about Jackery Explorer 300 Plus
Can the Explorer 300 Plus run a fridge?
Only a small one for a short time. Jackery's own example is a 90 W mini fridge for about 2.5 hours. Divide 288 Wh by the fridge's average draw for a rough running time, which will be lower in practice.
How long does the Explorer 300 Plus take to charge?
Jackery lists 2 hours from the mains, 5.5 hours from a car socket and 4 hours through USB-C. Solar charging time depends on the panel: the specification table gives 9.5 hours with a 40 W panel.
Is the Explorer 300 Plus the same as a home battery?
No. It is a small portable power station that you plug devices into. An installed home battery is wired into your electrics by an electrician. See our guide to plug-in and installed home batteries.
