How Long Does the Bluetti EB150 Last?

Do you own a Bluetti EB150 solar generator or are you thinking about buying one and are wondering how long it lasts?

You’ve come to the right place. 

In this post, we talk about the battery life and the lifespan (life cycles) of the Bluetti EB150. 

We have a separate in-depth review of the Bluetti EB150. Here, we focus on how long it can power different appliances and devices, and how many years you can expect it to last. 

Bluetti EB150: Quick Overview

If you don't have the time to read our full review of the Bluetti EB150, here’s a quick overview. 

The Bluetti EB150 solar generator has a capacity of 1500Wh. It’s equipped with a pure sine wave inverter with a continuous output of 1000W and a surge output of 1200W. 

You can power appliances and devices via its multiple outlets including two AC ports, five USB ports (including USB-C PD) and one 12V car port. 

You can recharge it via solar (max 500W) or an AC outlet. 

The Bluetti EB150 is an ideal solar power station for camping, RVs, road trips, camper vans and home backup of devices and small appliances.

Let’s start by talking about the EB150’s battery life. The 1500Wh capacity is big enough to provide hours of runtime for small and medium size appliances. 

You can also recharge devices dozens of times before the battery dies. 

Here’s a table showing the estimated runtime of various appliances and devices.

Laptop (60Wh)

21 recharges

Smartphone (10Wh/2600mAh)

127 recharges

CPAP (60W)


Mini fridge (40W)


TV (100W)


Drone (40Wh)

31 recharges

Drill (800W)


Mobility scooter battery (460Wh/36Ah)

2-3 recharges

You can calculate the runtime of any device or appliance using the following formula. 

Runtime = (1500Wh x 0.85)/Appliance wattage

If it’s a device that you want to recharge, replace wattage with the device’s battery capacity (in Wh). If capacity is given in Ah, multiply that by the battery voltage to get watt-hours. 

Note: In real life conditions, battery life will be less than indicated since most people plug in multiple appliances and devices. The above table is just to give you an idea of how useful the solar generator is for your particular situation.

As you can see in the formula, we are assuming that only 85% of the capacity is usable. This takes into account the battery’s depth of discharge as well as inverter losses. 

Generally, the Bluetti EB150 is best suited to running small and medium size appliances, in addition to recharging devices. 

It ensures you stay under the 1000W load limit and increases battery life. 

I wouldn’t recommend running a 750W heater or an 800W refrigerator with the EB150. While it’ll power these appliances, they’ll drain the battery fast. 

How To Increase Bluetti EB150 Battery Life

Here are some tips for squeezing more hours out of the Bluetti EB150. 

  • Whenever you can, power appliances and devices via the USB outlets and DC car port. This bypasses the inverter, which reduces energy losses. Inverters are not 100% efficient and lose some of the power that passes through them.
  • Turn off the AC switch whenever you are not using any of the AC outlets. This turns off the inverter and prevents idle power losses.
  • Use low wattage appliances that draw less power from the battery.
  • Switch to higher efficiency appliances and electronics that use less power. For instance, LED lights instead of incandescent or replacing your old mini fridge with a newer and more efficient one.
  • Store and use the solar generator in cool temperatures. Too much heat or cold will reduce battery life. They reduce battery capacity and can make the battery discharge quicker. 

What’s The Lifespan of the Bluetti EB150 Solar Generator?

How long a solar generator lasts depends mostly on how long the battery lasts. The battery is the most important and expensive part of a solar generator. 

So once it dies, the only option is getting a new solar generator. We don’t yet know of any company that sells a portable solar generator with replaceable batteries. 

Battery lifespan, on the other hand, depends on its chemistry, how often it’s charged and discharged, and how well it’s taken care of. 

Lithium batteries last longer than lead acid batteries. But even among lithium-ion batteries, there’s a big difference in longevity. 

The Bluetti EB150 contains a lithium polymer battery, which has one of the shortest lifespans among lithium batteries. 

You can expect a lifespan of 500 cycles to 80% capacity. That is, after charging and discharging the battery 500 times, capacity will reduce to 80%, which is 1200Wh. 

Battery capacity will keep going down after that. Bluetti says the total lifespan of the EB150 is 2500 cycles. 

In contrast NMC and LCO lithium-ion batteries can last for between 3000 and 5000 total cycles (500-800 cycles to 80% capacity) and LiFePO4 batteries last 5000-10000 total cycles (2000-4500 cycles to 80% capacity). 

Generally, LiPo batteries last about 3-5 years, so that’s roughly how long the Bluetti EB150 will last. 

How To Increase The Lifespan Of The Bluetti EB150

Here are some tips to increase the longevity of the Bluetti EB150. 

  • Try to cycle the battery no more than once a day. Only charge the solar generator once each day. The more you charge and discharge the battery, the shorter its lifespan.
  • Store and use the solar generator in cool temperatures. Both extreme heat and cold are bad for its longevity and performance.
  • Protect the solar generator from the elements. Do not expose it to rain, snow, wind, or direct sunshine (keep it in a shade or inside when charging with solar).
  • Don't bang it around too much especially if you travel often with the solar generator. 

Longer Lasting Alternatives 

If you want a solar generator that will last longer than the EB150, we recommend the two new models from Bluetti — the AC200P and AC200MAX solar generators. 

These have lithium phosphate (LiFePO4) batteries that can last as long as 10 years with good care. 

They are a bit more expensive than the EB150, but you get better value for your money thanks to their longer lifespan, larger capacity, and higher output.
