Charging Speed
How fast does the EcoFlow Delta 2 charge from mains?
EcoFlow's X-Stream technology pushes the Delta 2 from flat to full in around 80 minutes using a standard UK mains socket. That is genuinely fast for a 1kWh-class unit. The charger draws approximately 1,200W, which means a single 13A socket handles it without any fuss. You can also combine mains and solar simultaneously to shorten charge time further when on a pitch with panels out.
How fast does the Jackery Explorer 1000 v2 charge from mains?
The Jackery Explorer 1000 v2 charges in around 1.8 hours — roughly double the time of the Delta 2. That is still reasonable for a 1kWh battery, and for most leisure users who plug in overnight or between weekend trips it will never feel slow. However, if you rely on short daytime charges — for example between sessions on a campsite with metered electric hookup — the extra time could matter.
The EcoFlow Delta 2 wins on charging speed by a clear margin. For users who value fast turnaround the 80-minute mains charge is one of its standout selling points in the 1kWh class.
Weight and Portability
At 14kg the EcoFlow Delta 2 is manageable but not light. For van life, motorhome, or static campsite use where it stays put most of the time, the weight is rarely an issue. If you are carrying it across a field or up steps to a flat, the extra 3kg over the Jackery does become noticeable.
The Jackery Explorer 1000 v2 weighs 11kg and is genuinely easier to carry one-handed for short distances. For festival camping, boat use, or any situation where you carry the unit frequently, 3kg less makes a tangible difference over the course of a weekend.
The Jackery Explorer 1000 v2 wins on portability. If carrying weight matters in your use case, it is the more practical choice. If the unit will mostly stay in one place, the weight difference is largely irrelevant.
Noise Levels
Jackery rates the Explorer 1000 v2 at sub-22dB during normal operation. To put that in context, a quiet library is around 30dB. Sub-22dB is extremely quiet — you would need to be close to it in a silent room to hear the fan at all under light loads. This makes it one of the quietest units in its capacity class, and a strong option for bedroom use during a power cut, overnight camping, or running alongside a baby monitor.
EcoFlow does not publish a decibel rating for the Delta 2. Under sustained high-wattage output the fan ramps up audibly. It is not loud enough to cause real nuisance in a van or living room, but it is noticeably present in a way the Jackery is not.
The Jackery Explorer 1000 v2 wins on noise. Its sub-22dB rating is class-leading. EcoFlow's silence under light load is adequate, but it cannot match Jackery's published figure.
Solar Charging
The EcoFlow Delta 2 accepts up to 500W of solar input. In the UK, where peak solar irradiance is lower than in southern Europe, a higher input ceiling is particularly valuable because it helps compensate for reduced panel efficiency on cloudy or overcast days. With two EcoFlow 220W panels connected you can push close to the input limit on a bright summer day, potentially recharging from flat in under 3 hours in good conditions.
The Jackery Explorer 1000 v2 accepts up to 400W of solar input. A pair of SolarSaga 200W panels running at 80% efficiency on a clear summer day would deliver around 320W, giving a full charge in roughly 3.5 to 4 hours.
The EcoFlow Delta 2 has the higher solar ceiling at 500W vs 400W. For UK buyers relying on solar as a primary source, particularly in Scotland or on trips in spring and autumn, that extra 100W of input headroom is worth having.
UPS and Home Backup
The EcoFlow Delta 2 includes a UPS mode that detects a mains failure and switches to battery in under 30 milliseconds. Most sensitive electronics — routers, NAS drives, medical devices, desktop computers — require a switchover of 20ms or less to avoid restarting. The Delta 2's 30ms figure is borderline for some equipment but works reliably for the majority of home electronics.
The Jackery Explorer 1000 v2 does not include a UPS mode. It can provide power during a cut if you manually plug devices into it, but there is no automatic switchover. For users who want automatic backup protection for sensitive equipment, the absence of UPS mode is a significant limitation.
The EcoFlow Delta 2 wins clearly on home backup capability. Its UPS mode is a feature the Jackery Explorer 1000 v2 simply does not offer.
Warranty and Value
Both EcoFlow and Jackery offer a 5-year warranty on their flagship power stations when purchased through authorised UK retailers. This is among the best coverage in the portable power category. Both brands have UK-based customer support and honour warranty claims without requiring international returns.
The EcoFlow Delta 2 typically retails between £399 and £499 in the UK, while the Jackery Explorer 1000 v2 is priced around £599. For the £100–£200 premium you pay for the Jackery you receive 3kg less weight, lower published noise, and marginally more capacity. You give up UPS mode, X-Boost, higher solar input, faster charging, and one extra AC outlet.
- Fastest mains charge — 80 minutes
- UPS mode — automatic switchover under 30ms
- X-Boost to 2,200W for high-draw appliances
- Higher solar input — 500W vs 400W
- 4 AC outlets vs 3
- Better value — typically £100–£200 less
- Heavier — 14kg vs 11kg
- No published noise rating
- Audibly louder under heavy load
For most UK buyers the EcoFlow Delta 2 is the stronger choice at this capacity level. It charges in 80 minutes, handles appliances up to 2,200W via X-Boost, accepts 500W of solar, includes UPS mode for power cut protection, and costs significantly less than the Jackery. The feature set it delivers for £399–£499 is difficult to match in its class.
The Jackery Explorer 1000 v2 earns its place for buyers who carry their power station frequently on foot, prioritise low noise for sleeping areas, or simply prefer the Jackery ecosystem. Its 11kg weight and sub-22dB noise rating are real, measurable advantages — they just come at a cost premium and with meaningful feature trade-offs.
