FlexSolar vs TWELSEAVAN Specs
Rated Power Output
The FlexSolar 60W model provides a steady 60 watts under direct sunlight, dropping to 30-40 watts in cloudy conditions. It is designed for small-to-medium devices up to 300Wh. The TWELSEAVAN 120W model doubles that output, offering significantly more energy harvest. This higher wattage allows you to charge larger power stations or multiple devices faster. If you need more power for extended trips, the TWELSEAVAN has the clear advantage. The FlexSolar is better for lighter loads or quick phone top-ups where portability is key.
Conversion Efficiency
Efficiency determines how much sunlight becomes usable electricity. The FlexSolar uses A+ monocrystalline cells with a 24% conversion rate. The TWELSEAVAN utilizes upgraded HPBC cells, achieving up to 25.8% efficiency. This higher percentage means the TWELSEAVAN captures more energy from the same amount of sun. Both panels use ETFE coatings for durability and light transmittance. The TWELSEAVAN’s superior efficiency makes it the better choice for maximizing output in limited sunlight or compact spaces. The FlexSolar remains efficient but trails slightly in raw conversion capability.
Portability and Weight
Weight and folded size matter for hiking or camping. The FlexSolar weighs 6.4 lbs and folds to 13.8×9.1 inches. The TWELSEAVAN weighs 7.05 lbs and folds to 16.6×15.7 inches. The FlexSolar is lighter and more compact when folded, making it easier to carry in a backpack. The TWELSEAVAN is slightly heavier and bulkier, comparable to a gaming laptop. If every ounce counts, the FlexSolar wins. However, the TWELSEAVAN includes a magnetic handle and angle guide for easier setup, which may offset the slight weight difference for some users.
USB Charging Ports
Direct device charging is a major convenience. The FlexSolar offers three USB ports: QC2.0 (15W), QC3.0 (18W), and PD3.0 USB-C (60W). It also includes a DC port. The TWELSEAVAN provides a USB-C port (60W max), a USB QC3.0 port (18W max), and a standard USB port (5V/3A). Both support simultaneous charging with intelligent chips to adjust current. The FlexSolar offers an extra USB port, giving you one more connection point for devices. Both deliver the same 60W PD output on their primary USB-C ports. The FlexSolar has a slight edge in total port count.
Power Station Compatibility
Connecting to a portable power station requires the right cables. The TWELSEAVAN includes an MC4 5-in-1 cable with adapters for Anderson, XT60i, 8020, 7909, and 5521 connectors. It also provides three DC adapters, ensuring compatibility with 99% of major brands like Jackery, EcoFlow, and Bluetti. The FlexSolar lists a DC port (20-28V) but does not mention included adapters or specific power station compatibility. You may need to buy separate cables for the FlexSolar. The TWELSEAVAN’s inclusive cable kit makes it much easier to connect to most power stations out of the box.

Yes, both panels are built to withstand rain. Each unit carries an IP65 waterproof rating, ensuring protection against water jets from any direction. This makes them suitable for outdoor camping or emergency use where sudden weather changes occur. You can rely on them to continue functioning during light to moderate rainfall.
How do the folded sizes compare?
The FlexSolar 60W folds to 28.1 by 33.8 inches with a thickness of 0.2 inches. The TWELSEAVAN 120W folds to 14.4 by 20.5 inches but is thicker at 1.6 inches. The FlexSolar is larger in surface area when closed, while the TWELSEAVAN is more compact in footprint but bulkier in profile.
What ports are available on the TWELSEAVAN panel?
The TWELSEAVAN 120W panel features both USB-C and MC4 output ports. The USB-C port allows for direct charging of modern devices like laptops and phones. The MC4 connectors enable you to link the panel to a solar charge controller or power station for more flexible power management setups.
Is the FlexSolar panel suitable for RV camping?
The FlexSolar 60W is suitable for light RV use, particularly for topping up small devices. However, it lacks the dedicated RV application label found on the TWELSEAVAN model. If you need higher wattage for RV systems, the TWELSEAVAN 120W is a more robust option designed specifically for camping and RV environments.
