Inergy Flex 1500 Review (2023): Should You Get It?

Are you in need of a portable power station that you can rely on when there is no power? If yes, you should consider Inergy flex 1500.

Inergy is a popular company known for making quality products. This company sounded familiar to me since I have a friend that uses the Kodiak solar generator from Inergy. Since I wanted to take my family for our first camping trip, I was searching for a good power station, and Inergy came to mind.

I decided to get Inergy flex 1500 since it was lightweight and could help me power most of our devices during the trip. I later created this post to help you learn everything you need to know regarding this portable power station. Read on!

Inergy flex 1500 review and breakdown

This model is the successor to the Inergy Apex power station. Inergy Flex 1500 comes with an expandable 12V lithium-ion battery. You can use it to power different items such as your fridge, smartphone, and lights.

Though some people assume that this power station can support 1500 watt-hours, it runs at 1100 watt-hours with a 3000- watt pure sine surge.

The outputs of this solar generator include 2 USB-C ports, 2 USB-A ports, 2 x 13.8V DC ports, 6 x 110V wall outlet plugs, and 2 x 5.5 mm DC outputs. You, therefore, have numerous options to charge different devices if you don’t have power.

This portable power station can power through a wall charger, car charger, and solar panels. Inergy flex 1500 is a modular system made up of a lithium-ion battery, power console, and MPPT supercharger. It also runs on sleek technology, making it convenient to handle, and comes with a handy LCD screen.

You can use this power station indoors or outdoors. It is easy to use since it is designed to be plug-and-play. Another thing that I like about this power station is that it works silently and does not emit fumes. Since it weighs 30 lbs, it is easy to move around.

The manufacturer also includes a carry handle that enhances portability. Once you purchase this model, you will get a two-year warranty for it.

Inergy flex 1500 Features

Battery capacity

Inergy flex 1500 makes use of a 1069 Wh 12V lithium-ion battery. What makes this model stand out is that its battery capacity is expandable.

It can accept a maximum of 96 flex batteries. Since the battery is detachable, you can easily replace it with a new one when it wears out. This portable power station is plug-and-play. It is, therefore, easy to use and allows multiple connections.


This portable power station is a modular system that is made up of three parts, the MPPT supercharger, the lithium-ion battery, and the power console. The console includes a 13.8 V of DC power and a 1500W pure sine wave continuous inverter with a surge capacity of 3,000W.


Since this power station is light and compact, you can easily bring it with you when camping or boating. It weighs around 29 lbs and has compact dimensions that ensure it does not occupy much floor space.


You don’t have to depend on fossil fuel power to utilize this power station since you can charge it through solar panels. Charging it with solar panels is convenient since the battery can charge in less than 6 hours. This model is capable of handling 600 W solar input.

Apart from solar power charging, you can also power this power station with a car charger or an AC wall outlet. If you utilize a wall charger or car charger, it may take longer than using solar panels. Some people find the charge speed of either of these options to be slow since it can take up to 11 hours.


Before investing in one, you should assess the number of ports that a power station comes with. Inergy flex 1500 does not disappoint since it has many of them.

They include 2 USB C ports, 2 USB A ports, 2 DC ports, and 6 120/110 V wall outlet plugs. The problem with this model is that its wall outlet plugs are very close, making some hard to use.

Are there alternatives to Inergy flex 1500

Yes. Some of them include Yeti 3000X, Yeti 6000X, and Inergy Apex. You should take the time to compare these power stations’ features before picking one.
