Jackery 1500 New Review | The Power of a Portable Power Station with LFP and 6,000 Charge Cycles

“How many years until I need to replace a portable power station?”

This is actually a question you should confirm properly before purchasing. With cheaper models, the battery often degrades within a few years, and you might find the capacity has dropped to less than half before you know it.

The product we are covering this time, the “Jackery Portable Power Station 1500 New”, is the latest 1500Wh class model from Jackery, released on November 10, 2025.

Its main features are its long-life design with 6,000 charge/discharge cycles and over 10 years of use thanks to the adoption of Lithium Iron Phosphate (LFP) batteries, and a UPS function that switches within 0.01 seconds (10ms) during a power outage.

It is a unit well-suited for remote workers and freelancers looking to create a “power environment that never stops work.”

First, let's organize the differences from the old model (1500 Pro)

The 1500 New is a legitimate evolution of the old “1500 Pro” model. The main changes are as follows.

• Battery: Changed from Ternary Lithium-ion to Lithium Iron Phosphate (LFP)

• Charge/Discharge Cycles: Significantly extended from 1,000–2,000 to 6,000

• Rated Output: Increased from 1,800W to 2,000W

• Size: Approximately 44% more compact, weight reduced from 17kg to 14.5kg

• UPS Function: Newly equipped (switches within 0.01 seconds/10ms)

• Fast Charging: 2 hours to as fast as approx. 1.5 hours (1.3 hours in emergency charging mode)

• Operating Temperature: Expanded from -10℃–40℃ to -20℃–45℃

• Self-discharge rate: Only about 5% capacity loss even after 1 year of storage

While maintaining a capacity of 1,536Wh, which is almost the same as the old model, almost all specifications have been improved.

Why LFP batteries are close to “no replacement needed”

The 1500 New has a charge/discharge cycle life of 6,000 times. Calculated theoretically, it lasts over 16 years even with full daily charging and discharging, which is why Jackery markets it as having a "10-year long life."

For comparison, older ternary lithium-ion models typically last 1,000 to 2,000 cycles, and many competing LFP models offer 3,000 to 4,000 cycles, making the 1500 New's 6,000 cycles top-tier for its class.

It is designed to maintain 70% of its battery capacity even after 6,000 cycles, offering high investment efficiency in terms of long-term asset value.

Furthermore, it has a low self-discharge rate, losing only about 5% of its charge even if left for a year when fully charged. Preventing the situation where you find it at zero charge during a power outage is a crucial point for disaster preparedness.

UPS Function and Pass-Through: Benefits Directly Relevant to Remote Workers

For remote workers and freelancers, the biggest fear is a sudden power outage while working. This carries the risk of losing unsaved data or damaging files if the power cuts out while writing to an external HDD.

The 1500 New is equipped with a UPS function that switches within 0.01 seconds (10ms). Because it automatically switches to the internal battery the moment a power outage occurs, connected devices remain powered without ever "noticing" the outage.

It also features a pass-through function, allowing you to charge the 1500 New while simultaneously powering connected devices. You can keep your desktop PC or NAS plugged in and running daily.

However, the UPS function is different from industrial UPS units designed for precision medical equipment or high-precision servers. While sufficient for backing up general PCs and peripherals, please check with the manufacturer before using it with medical equipment.

Specs Summary: What Can It Actually Be Used For?

Main Specifications

• Battery Capacity: 1,536Wh

• Rated Output: 2,000W (4,000W surge peak)

• Charge/Discharge Cycles: 6,000 cycles (until 70% capacity remains)

• Weight: 14.5kg

• Dimensions: 242×330×221mm

• Charging Time: As fast as approx. 1.5 hours with AC fast charging (1.3 hours in emergency charging mode)

• Operating temperature: -20°C to 45°C

• UPS switching: within 0.01 seconds (10ms)

• Self-discharge: drops by only about 5% after 1 year of storage

• Output ports: AC x3, USB-C x2 (30W/100W), USB-A x1, car outlet x1

Usage scenario for remote work

• For a desktop PC (200W), it runs for about 6 hours

• For a laptop (30W), it provides about 40 charges

• For a router + NAS + monitor setup, it can provide several days of backup power

Three ways to charge: Solar is also supported

There are three ways to charge the 1500 New: AC wall outlet, solar panels, and car outlet.

AC fast charging is quite quick, taking as little as 1.5 hours, which is fast enough to recover before leaving in the morning even if you forgot to charge it the night before.

Using Jackery SolarSaga series panels is recommended, and by connecting multiple 100W panels, you can supplement charging even in environments where commercial power is cut off.

Points of concern / Who this is not for

To be honest, the list price of 149,800 yen is not cheap. It is often heavily discounted during sales, so checking the official Jackery site or Amazon sale timings is the smart way to buy.

Also, although the 14.5kg weight has been reduced, it is not suitable for frequent carrying. It is basically a model for indoor use.

Who this is for

• Those who want to eliminate the risk of power outages during remote work or telework

• Those who want a power source that does not easily degrade even when stored long-term as disaster preparedness

• Those who want to secure 1 to 3 days of power for camping or car camping

• Those who want to invest in equipment that can be used for over 10 years

Who it is not for

• Those who carry it around frequently (a lighter model would be more appropriate)

• Those who want to keep the budget down (do not want to spend over 100,000 yen on a 1500 Wh class unit)

How long can you use a refrigerator for camping or car camping?

If you connect a car refrigerator (around 50W), a capacity of 1,536Wh allows for approximately 30 hours or more of continuous operation. For a 1-night, 2-day camping trip or car camping, you can run the refrigerator without worry, which almost eliminates the stress of food management. With an electric blanket (50W), you can similarly use it for over 30 hours, and even an electric kettle (1,000W) can be used for over an hour.
