Renogy E.Flex 30W Portable Solar Panel

The Renogy E.Flex 30W Portable Solar Panel is a foldable, lightweight solar charger designed for camping, hiking, and other off-grid activities where keeping phones, tablets, and other low-power devices charged matters. Weighing 1.23 lbs and folding to 10.55 x 8.86 x 0.71 in, it fits in or attaches to a backpack and deploys in seconds. It charges two devices at once through a USB-C PD3.0 port (20W max) and a USB-A QC3.0 port (18W max), plus a DC output port for additional device types.

Compact Enough to Carry Every Day

At 1.23 lbs and folded to roughly the footprint of a small laptop, the E.Flex 30W goes where rigid panels cannot. Four included carabiners clip directly to a pack, a tent line, or a branch, so the panel can harvest sun while you move through camp or rest on the trail. Six metal hanging holes give additional attachment options when carabiners are not the right tool. The result is a charging solution that does not require a dedicated bag or a flat surface to be useful.

23% Cell Efficiency in a Shade-Tolerant Design

The E.Flex 30W achieves a cell efficiency of at least 22.4% and is rated for a maximum power output of 30W at standard test conditions. The panel uses a fully parallel cell design that reduces power-generation losses when part of the panel is shaded, which matters on a trail where tree cover is intermittent. Optimum operating voltage is 15.96V at 1.88A. The panel operates across a temperature range of 14°F to 149°F (-10°C to +65°C), covering most conditions from cold-morning starts to hot desert afternoons.

Dual Fast-Charge Ports for Two Devices at Once

The USB-C port supports PD3.0 at up to 20W, and the USB-A port supports QC3.0 at up to 18W, so a phone and a tablet, or two phones, can charge simultaneously without splitting a single slow port. A DC output port extends compatibility to device types that do not use USB. Charging speed depends on available sunlight; for best results, orient the panel toward direct outdoor sun rather than placing it near a window.

Specifications

Who This Is For and Isn't

The E.Flex 30W suits hikers, backpackers, and car campers who need to keep phones, tablets, and similarly sized low-power devices charged without carrying a heavy rigid panel. The carabiner attachment system makes it practical for anyone who wants to charge while moving or hanging the panel from camp gear rather than propping it on a flat surface.

The E.Flex 30W is designed for low-power consumer electronics and is not intended to charge a house battery bank or feed a solar charge controller. It does not include a charge controller, battery, or mounting hardware for a fixed vehicle or rooftop installation.

Common Questions

What devices can the E.Flex 30W charge?

The Renogy E.Flex 30W Portable Solar Panel is designed for low-power consumer electronics such as mobile phones and tablets. The USB-C PD3.0 port delivers up to 20W and the USB-A QC3.0 port delivers up to 18W, and a DC output port is also available for compatible devices.

How do I attach the panel to my backpack or camp setup?

The E.Flex 30W includes four carabiners and has six metal hanging holes, so it can clip directly to a backpack, a tent line, or a tree branch. No tools or additional hardware are required to hang or carry the panel during outdoor activities.

Will the panel work if part of it is in shade?

The E.Flex 30W uses a fully parallel cell design that reduces power-generation losses when part of the panel is shaded. Output will still decrease under partial shade, but the parallel layout limits how much a shaded section affects the rest of the panel compared to a series-wired design.

Can the panel charge through a window?

The E.Flex 30W can produce some output through a window, but output will be low due to reduced sunlight intensity indoors. For best results, the panel should be used outdoors in direct sunlight.
