The EcoFlow Delta 1300 is a unique solar generator well-known for its battery management system and its AC charging platform. The overall features of this generator make it great for camping, workshops, and mobile usage. This device comes with specifications that make it an excellent choice for fast charging.

One of the exciting features of this device is its built-in MPPT charge controller, which plays a role in its fast charging. The MPPTcontroller helps regulate the battery charging process to ensure that the battery is charging appropriately.

There are three ways to charge the Delta 1300. You can plug it directly into your solar panel, AC wall outlet, and car outlet.

  • When plugged into a solar panel setup (rated up to 400W of total output), it takes four hours for a complete charge.
  • With an AC outlet, it takes two hours.
  • If you use your car, then you may wait as long as 18 hours for a full charge.

Even though you can charge this generator through a solar panel, AC wall socket, or a car outlet, there’s one minor limitation. Unlike some other generators on the market, you can’t charge the Delta 1300 by combining multiple inputs. In other words, you can’t charge it by your solar panel, wall socket, and car altogether. You need to choose one.

Features of the EcoFlow Delta 1300

The Point Zero Energy Titan

The Point Zero Energy Titan is known to be a dependable and versatile solar generator. It’s made up of very efficient and durable components that result in an incredible user experience. The capacity of one battery pack with the Titan is 2,000Wh, and it’s a lithium-ion cell type.

One of the enjoyable features of the Titan is its removable and expandable battery, which can also be charged rapidly. Like the other power stations already mentioned, you can charge the solar generator via a wall outlet, a car charger, and solar panels.

  • With 1,000 watts of solar panels, the power station takes 2-4 hours for a full charge with one battery.
  • The AC charger can charge the battery pack of the Titan in around 3.5-4 hours.
  • Impressively, you can also charge via an AC wall charger, solar panels, and a car charger simultaneously.

Note that the Titan can also use two wall chargers at the same time for a fast-charging experience. However, this requires you to use two batteries. The Titan can also charge with up to 2,000W of solar panels with two batteries.

With the no-load power, the generator has an impressive efficiency score of up to 92%. Usually, the larger inverter needs a higher amount of power, while the smaller ones don’t need much power to operate.
