Mesuvida 30 W folding panel, five outputs including MC4 and DC, 1.1 kg stated review
The largest port count of the nine — MC4, DC, two USB-A and a USB-C — on a 30 W panel that fills eight of the eleven columns this hub compares, matched only by the VTOMAN.
The bottom line The most connectable panel on this shelf, and still silent about the regulator a battery would want.
What this listing puts on record
A 30 W folding panel with five outputs — MC4, DC, two USB-A and one USB-C — monocrystalline cells at a stated 23.5 %, PD 18 W on the USB-C, an IPX4 rating, 30 × 23 cm folded, 1.1 kg, an adjustable stand, a 1.5 m DC lead, three DC adapters and two carabiners.
Five outputs is the whole argument
Most panels here offer two sockets and stop. This one offers five, and the two that matter are the ones a phone cannot use: MC4 and DC. That is what turns a panel from a phone charger into something that can be pointed at a power station, and the listing goes further — it describes wiring several panels in parallel or in series, and states that the parallel lead is not supplied. Saying what is missing from the box is rarer than it should be.
Where the 18 W stops
PD 18 W is printed for the USB-C, and nothing else. No 5 V step, no 9 V step, no current at either. Two panels on this shelf name Power Delivery at all; this is the one that names it without its figures. QC 3.0 is claimed for the USB sockets in the same breath, again without numbers.
The stand, and the dimension that is missing
An adjustable stand is listed, and the maker explains what it is for: setting the angle to the sun. That is one of only two listings here to describe how the panel is stood up at all. What is not here is a folded thickness to go with the 30 × 23 cm, or any unfolded size — so the area those cells cover, which is the thing the stand is angling, is left blank.

What it does well, and where it gives way
Strengths
Five outputs including MC4 and DC — the largest port count of the nine, and what lets it reach a power station rather than only a phone
Names monocrystalline cells and a 23.5 % conversion rate, and lists a DC lead, three DC adapters, two carabiners and an adjustable stand as supplied
States that panels can be wired in parallel or in series, and says outright that the parallel lead is not in the box
Compromises
PD 18 W is named with no voltage or current steps behind it
The folded size is 30 × 23 cm with no thickness, and the unfolded size is absent altogether
No charge controller named, on the panel here most obviously aimed at feeding a battery

What people ask before buying
Does the MC4 lead make this a charging system?
It makes it connectable. The listing describes a built-in MC4 cable, three DC adapters and the option of wiring panels in parallel or in series, and it names no regulator anywhere. A panel wired to a battery still needs the regulation to come from somewhere, and on this listing that somewhere is not stated.
How big is it folded?
30 × 23 cm is stated. The thickness is not — and on a panel that carries a stand and a built-in lead, thickness is the dimension that decides whether it lies flat in a pannier. The unfolded size is missing entirely, which is true of all nine panels here.
SOLIX PS30 folding solar panel · 30 W stated · USB-A and USB-C · IP65 · two carabiners and an 18-month warranty · no size, mass or efficiency published
The emptiest specification of the nine: a 30 W folding panel with USB-A, USB-C and an IP65 rating, and no mass, no size, no cell type and no efficiency figure anywhere on the page.
Best for: A buyer choosing on the brand and the IP65, who does not need the panel compared with anything.
40 W folding solar module · XT60, USB-A and USB-C · 23 % efficiency stated · IPX4 · fold-out feet and a carry handle · XT60 and USB-C leads supplied · no size or mass published
A 40 W module sold first as an accessory to the maker's own battery power station, with an XT60 lead in the box, fold-out feet to aim it at the sun, and no dimension or mass published anywhere.
Best for: An owner of the maker's own battery power station, for whom the XT60 lead in the box settles the question.
15 W folding solar panel · three rubber-covered connectors · up to 24 % conversion stated · IP67 · 19.8 × 22.4 × 1.8 cm folded · 0.45 kg — the lightest published weight of the nine
The lightest and smallest panel of the nine at 0.45 kg and 19.8 × 22.4 × 1.8 cm folded, and also the lowest peak figure here at 15 W — the trade is written on the label.
Best for: A day pack where the panel has to disappear between uses and a phone is the only thing being charged.
