EcoFlow 110 Review

The EcoFlow 110 is a high-performing and extremely portable solar panel — and one of the only fully waterproof models we've tested.

Direct Solar Charging Speed

If a solar panel doesn't work well in direct sunlight, it's not worth buying. The EcoFlow 110 put out decent power during direct sunlight hours, particularly when angled toward the sun.

The EcoFlow 110 uses monocrystalline solar cells with a 23% conversion rate. When it was new, it put out more charge than any other model in our direct solar charging test. After a few years of use, that output has dropped noticeably, though it's still about average within our test group.

On a hot, sunny day in Colorado at 5,000 feet, the EcoFlow 110 generated 43.5 watt-hours of charge in one hour. This is nearly 20% of the total capacity of a 240-watt-hour battery — just about average for solar panels of this size. Each panel's watt output was also monitored during direct solar charging speed testing. The EcoFlow 110 consistently put out an average of 38.3 watts during peak sun. While it used to perform well above average, it now sits right about average in terms of output.

When we hooked the EcoFlow's MC4 cables to a voltmeter, it measured 23.4 volts. This is one of the higher voltage panels. However, we found the output varied consistently as atmospheric conditions shifted. The watt output would change when we changed the panel's angle, but even when we didn't move the panel, it would fluctuate on every panel. Either way, this is still a fairly efficient solar panel in direct sunlight.

Indirect Solar Charging Speed

The best solar panels create energy when the sun isn't shining as bright, and these are the panels we think you should consider. We simulated a cloudy day using a large white sheet and tested every panel simultaneously.

The EcoFlow 110 performed similarly in our indirect solar charging test as it did in direct sunlight. That is, formerly impressive, now about average among similarly-sized panels.

Many panels in our Big White Sheet indirect solar charging test saw a significant drop in power output under the white sheet. The EcoFlow 110 did as well, once again performing about average for a panel of this size. Under the white sheet test, it generated 13.5 watt-hours of charge in an hour. This is just shy of average charging in indirect sunlight.

The EcoFlow 110 saw less of a decrease in charge output than most other models during this test. Some panels generated more power, but the EcoFlow was consistently a top performer.

In previous years, the EcoFlow performed the best on average across both direct and indirect solar charging speed tests. In our most recent testing, it didn't perform the best, but it still generated a lot of power under our Big White Sheet.

Portability

The EcoFlow 110 is very portable and one of the lightest in this large-panel lineup, weighing a mere 8.8 pounds.

Impressively, it folds to just 1.5 inches thick. Its included carrying case makes storing cables and other accessories easier than most because the carrying case is larger than the average zippered pocket found on many other panels we tested.

The EcoFlow 110 folds down from four panels into a thin stack that easily fits inside the carrying case. Its carrying case zips closed and has a comfortable webbing handle that feels more comfortable and sturdy than the many thin, sharp plastic handles on other panels.

Functionality

The EcoFlow 110 is pretty functional overall. It has MC4 universal solar cable connectors with a single charging output. This means it can only charge one device at once, but you can chain this kind of panel together to send more power to your power station.

The carrying case of the EcoFlow 110 also functions as a handy way to angle the panel. This allows you to point the panel at the sun to increase solar output. While the case works to do this, it doesn't work as well as some other models with dedicated kickstand legs for this purpose. We appreciate the design because it saves weight, but it isn't perfect.

Also, since it uses MC4 connectors, you'll likely need to buy an extra cable or adaptor to hook the EcoFlow 110 to your portable power station. It would be nice if everything you need to start using your panel were included with the panel, but the connector cable you need for your power station can vary. So, we get it, but we'd still like it if the EcoFlow 110 came with everything to use it.

Should You Buy the EcoFlow 110?

The EcoFlow 110 is an all-around great-performing solar panel. It's one of the more powerful models we tested and is also waterproof. Furthermore, this 110-watt panel is often on sale, and it's an excellent price if you do get it at a discount. When discounted, it costs about the same amount as most of the best solar panels we tested. Overall, the EcoFlow 110 is an excellent choice for a solar setup for your next camping trip.
