Best lightweight in power stations and solar
About 1 kWh of LFP in a 23.8 lb box with 10 ms UPS switching; the light, simple choice, but it can't take an extra battery or charge below freezing.

Is it right for you?
Pros
- 1,070 Wh LFP, rated 4,000 cycles to 70% or more
- About 23.8 lb: the lightest 1 kWh station we list
- 1,500 W AC with a 3,000 W surge peak
- Switches to battery within 10 ms in UPS mode
Cons
- Not expandable: no extra battery
- Only three AC outlets, all 120 V
- Charges only between 0 and 45 °C, per Jackery's manual
- Last two warranty years need online registration (3+2)
- Best for
- Apartments and smaller homes that want one light, quiet box for phones, lights, a modem, a CPAP or a small fridge through an overnight outage.
- Not for
- Multi-day outages without solar, sump pumps with high start loads, anything 240 V, or storage in an unheated garage.
Our verdict
The Explorer 1000 v2 is the one to pick if weight matters. Jackery fits 1,070 Wh of LFP into about 23.8 lb, the lightest 1 kWh box we list, rated for 4,000 cycles to 70% or more. Three 120 V outlets share 1,500 W with a 3,000 W surge peak, and two USB-C ports (30 W and 100 W) handle phones and a laptop without the inverter.
In UPS mode its manual says it switches to battery within 10 ms, which suits a modem, lamp or CPAP; Jackery warns it isn’t for equipment that needs 0 ms switching, such as servers. Jackery quotes about 1.6 hours to recharge from the wall. The same model is sold in Jackery’s Canadian store.
What you give up: it can’t take an extra battery, so 1,070 Wh is all you get between charges, and three AC outlets fill up fast. The warranty is 3+2 years, with the last two only after online registration.
Setup and safety
Indoors, and not in a cold garage. A battery makes no exhaust, so it belongs inside. Jackery’s manual gives charging between 0 and 45 °C and discharging between -10 and 45 °C, with charging and output limited outside that range, so don’t store it in an unheated garage or shed over winter and expect it to recharge there. Plug appliances straight into it; never feed a wall outlet from it with a male-to-male cord, which backfeeds the house wiring (how a transfer switch or interlock prevents it).
What 1 kWh runs. Forum threads about power stations repeat one lesson: buyers expected “whole home” and found that a 1 to 2 kWh station covers a fridge or a CPAP for hours, not a sump pump for days. A sump pump’s start-up surge can also trip a 1,500 W inverter, so check your pump’s starting watts first.
Solar and storage. Two DC8020 inputs take Jackery solar panels; the manual asks you to use the same model and number of panels on both, and at most two per input. Jackery quotes about 7.5 hours of sun with a SolarSaga 200W. For storage, recharge every three months and run a full charge and discharge every 6 to 12 months, ideally kept at 0 to 25 °C.

Explorer 1000 v2 questions
Can I add an extra battery to the Explorer 1000 v2?
No. It isn’t expandable, so its 1,070 Wh is the whole store of energy. If you think you’ll want more later, the EcoFlow DELTA 3 Plus is a similar size and takes an extra battery. Otherwise plan on solar panels or a generator to recharge it during a long outage.
Will it charge in a cold garage?
Not reliably below freezing. Jackery’s manual gives a charging range of 0 to 45 °C, with charging limited outside it, and a discharging range of -10 to 45 °C. Keep it indoors through winter and bring it into a heated room to recharge after use.
Is the UPS mode good enough for a computer?
For most home computers and routers, a 10 ms switchover is enough, though Jackery itself says it is not for equipment that needs 0 ms switching, such as servers. If a desktop restarts when the power blips, a dedicated UPS is the safer choice for that one machine.
How do I get the full five-year warranty?
Register it. Jackery describes the warranty as 3+2 years: three years standard, plus two more once you register the unit online. Do it when you unpack it, and keep the receipt.
