EcoFlow Delta Pro vs Bluetti AC300: Which Is Better?

by Hunter Kissam August 29, 2022 3 min read

When it comes to any new technology, you have to do some research to find the diamond in the rough. Fortunately, we can help with that. If you’re looking for a portable solar generator, then let’s compare two of the most powerful ones on the market: the EcoFlow Delta Pro vs Bluetti AC300!

Bluetti AC300 Performance

Bluetti AC300 is one of the most popular solar generators on the market. Here are some reasons why!

AC300 Charging Capabilities

With the right mix of solar and AC input, the AC300 can charge in an impressive 1.5 hours. With maximum solar input (2400W), it can still charge in under 2 hours.

AC300 Battery Performance

The AC300 has an impressive lithium-ion battery, with a capacity of 3072Wh and up to 3000W of output, allowing you to power most home appliances for a period. The battery is also fairly long-lasting, allowing for up to 3500 lifecycles before dropping 20% from its original capacity. For context, most lead-acid batteries only allow for 500 to 800 lifecycles before dropping 40%.

AC300 Special Features

The AC300 allows for EV fast charging, up to 5400W of total input at a time, and wind turbine compatibility. These are some unique features compared to other portable solar generators.

EcoFlow Delta Pro Performance

Now that you know what the AC300 is capable of, it’s time to talk about the EcoFlow Delta Pro, which broke the Kickstarter world record in 2021! For more information, read our full review!

Delta Pro Charging Capabilities

The EcoFlow Delta Pro allows for solar charging, AC charging, car charging, and even fast EV charging. For such a high-capacity battery, you’ll be surprised to learn that you can bring it to a full charge in less than 2 hours with EV fast charging or a combination of charging options. With solar panels alone (3x200W panels), the system should charge in around 5 hours.

However, the system can handle up to 1600W of input from solar panels at once, which could allow for much faster charging.

Delta Pro Battery Performance

The lithium-iron-phosphate (LFP) battery in the Delta Pro allows for an incredible 3.6 kWh capacity. One single Delta Pro unit is enough to power heavy-duty devices like dryer for a full cycle, power tools for a full workday, or a large refrigerator for over 24 hours. With up to 1600W of solar charging input and up to 7200W surge output, you can power most appliances in your home indefinitely in the right conditions.

Also, the system will last for over 6500 lifecycles before dropping 20% from its original capacity. That means that it will last for over 10 years with regular use before noticing a difference.

While they both use lithium-ion batteries, the LFP battery in the EcoFlow Delta Pro is long-lasting, set for 6,500 lifecycles before dropping 20% from its original capacity. That’s unprecedented for portable batteries, arguably making the Delta Pro the gold standard for solar generators.

Delta Pro Special Features

The EcoFlow Delta Pro can compound with up to two other Smart Batteries and attach to your home’s energy system. Using the Smart Home Panel will also allow you to attach to your home circuits to offset your energy during peak times and switch over instantly during an outage. This makes the Delta Pro the only portable power station capable of secure and instantaneous home backup.

These smart generators also has more options for charging, whether you need an AC outlet, USB, DC5521, or anything else.
