RedditProduct-line7.0 out of 10

One r/solar owner running Renogy's 200 W N-type E.Flex with a power station reports about 145 W at midday and about 190 W at the best angle, and rates it the best output per dollar of the portable panels they have owned. The same owner puts its weight at 14 to 17 lb and measured about 45 W from its USB-C port.

GoogleProduct-line7.0 out of 10

OutdoorGearLab, which buys the panels it tests and earns a commission through its Amazon links, measured Renogy's 200 W N-type E.Flex at 177 W over a one-hour test, 88 percent of its rating, and ranked it first of 12 portable panels with an Editors' Choice award. The same review marks it down for its 14.8 lb measured weight, kickstand legs that adjust less easily than rivals' and an IP65 rating below the IP67 and IP68 of other panels tested.

YouTubeBrand-level6.0 out of 10

Both channels found carry a tie to the panels they review. Freedom in a Can, which passes on a 10 percent Renogy code through Renogy's affiliate link, found no delamination on two 100 W flexible panels after 9 months and 9,000 miles. Johnny's Weekends, which earns Amazon commission on the panels it links, found Renogy's 200 W flexible panel performed well but trailed a CIGS panel under shade (2023, about 128,000 views).

AmazonProduct-line9.0 out of 10

Renogy's 100 W and 200 W N-type portable panels share one Amazon variation family, rated 4.5 from 963 ratings with 78 percent five-star and 6 percent one-star. Amazon's review summary reports power output as mixed and notes that no cables or station adapters come in the box.

Description

The Renogy E.Flex 100W is a four-fold portable panel with N-type cells, rated 100 W at STC with a 21.6 V open-circuit voltage and a 5.66 A short-circuit current on Renogy's Amazon listing. It unfolds to 45.08 x 22.99 x 0.12 in (1,145 x 584 mm), folds to 22.99 x 22.54 x 1.57 in and weighs 7.28 lb by the same listing. Renogy advertises 25 percent cell efficiency; the rated 100 W over the unfolded area works out to 15.0 percent for the whole panel. Besides its MC4 leads it carries a 45 W USB-C PD port and two USB-A ports rated 18 W and 15 W, so phones and cameras charge straight from the panel. Four kickstands set it at 40, 50 or 60 degrees, and a magnetic closure holds it folded. Renogy rates it IP65 on renogy.com, lists an ETFE coating on Amazon, and sells the MC4-to-station adapter cable separately. Renogy gives it a 2-year warranty and publishes no power-output warranty or temperature coefficient for it.
