Detailed overview: Blavor PN-W12 Pro 20,000 mAh 4-panel solar power bank
The Blavor PN-W12 Pro is a 20,000 mAh power bank designed for the outdoors, from a brand that has specialised in solar chargers for over ten years (and is regularly tested by the English-language press). Where a classic power bank stays tucked in a pocket, the PN-W12 Pro embraces outdoor use: rubberised reinforced casing, resistance to shocks, water splashes and dust (IPX5 rating), compass and carabiner to clip onto a backpack.
Its distinctive feature over basic solar packs is its four foldable solar panels. Folded, they protect the front; unfolded in the sun, they offer a far larger collecting surface than a single built-in panel: Blavor claims up to 1.2 A (4 x 300 mA under 25,000 lux), about seven times the yield of a single panel. It remains a top-up, but a much more serious one than on most solar packs on the market.
On the wired side, it offers a bidirectional 18 W USB-C Power Delivery output (which also recharges the pack) and two USB-A ports, i.e. up to three devices powered at once. It also carries a multi-mode camping light (including SOS) and a flashlight, very useful at camp or for a night-time fix. The battery uses lithium-polymer chemistry, and the whole is IPX5 certified.
Let us be clear despite its four panels: refilling 20,000 mAh from the sun alone takes many hours of full sunshine; the solar is a safety net on an expedition, not a substitute for USB-C charging (count about 6 hours for a full mains charge). With its 20,000 mAh (about 74 Wh), the PN-W12 Pro recharges most smartphones about four times and stays under the 100 Wh airline cabin limit. Rugged, complete and generous in capacity, it is aimed at those who want a reliable pack with a genuine foldable solar backup and a light, to head far and for longer with peace of mind.

Comparison
Around 35 to 45 euros, the Blavor PN-W12 Pro compares to the most sought-after high-capacity (20,000 mAh and up) foldable-panel solar power banks for the outdoors, via searches like "4 panel solar power bank" or "foldable solar power bank hiking". Here is how it stands against three alternatives: the Hiluckey 25000, the ADDTOP 25000 and the QTshine 26800.
| Criterion | Blavor PN-W12 Pro | Hiluckey 25000 | ADDTOP 25000 | QTshine 26800 |
|---|---|---|---|---|
| Capacity | 20,000 mAh | 25,000 mAh | 25,000 mAh | 26,800 mAh |
| Power | 18 W (USB-C PD) | ≈ 15 W | ≈ 15 W | ≈ 10 W |
| Solar panels | 4 foldable | 4 foldable | 4 foldable | 1 built-in |
| Lighting | Camping light + flashlight | Flashlight | Flashlight | Flashlight |
| Observed price | ≈ 40 € | ≈ 40 € | ≈ 40 € | ≈ 30 € |
In short, the Blavor PN-W12 Pro stands out with its 18 W USB-C output (the highest of the group) and its multi-mode camping light, on top of the four foldable panels it shares with the Hiluckey and ADDTOP (slightly higher capacity at 25,000 mAh). The cheaper QTshine makes do with a single panel and more modest power. As with all these packs, even with four panels the solar remains a top-up rather than a real charging source: the PN-W12 Pro is to be chosen above all for its USB-C power, its ruggedness, its camping light and its value.
Our tester's review: Guillaume Hoarau
We tested the Blavor PN-W12 Pro as an adventurer's power bank, and that is exactly where it makes sense. The rubberised casing inspires confidence: it takes knocks, resists water splashes (IPX5) and dust, and the supplied compass and carabiner let you clip it to a bag. Its real signature is the four foldable solar panels: unfolded, they capture far more sun than a single built-in panel (Blavor claims up to 1.2 A, about seven times a single panel). On the wired side, the 18 W USB-C Power Delivery output charges a smartphone at a good speed, and you can power three devices at once (USB-C, 2 USB-A). The multi-mode camping light and the flashlight are handy at camp. Its 20,000 mAh (about 74 Wh) provide roughly four full phone charges and stay under the 100 Wh airline cabin limit. Let us stay honest about the solar, as with all these packs: even with four panels, it takes many hours of full sun for a meaningful top-up, not enough to refill 20,000 mAh in a day (use the USB-C charge, about 6 hours, for a full refill). Seen for what it is, a rugged, generous outdoor pack whose four-panel solar is a serious backup but still a top-up, the Blavor PN-W12 Pro is a reassuring, complete and affordable outdoor companion.

They capture far more than a single panel (Blavor claims up to 1.2 A, about seven times a single panel), but it remains a top-up: refilling 20,000 mAh from the sun alone takes many hours of full sunshine. For a full charge, the USB-C input is better (about 6 hours).
Its 20,000 mAh (about 74 Wh) recharge most smartphones roughly four times, depending on their battery size. Enough to last several days of hiking without a socket.
Up to three: one on the USB-C port (18 W Power Delivery) and two on the USB-A ports. The USB-C port is bidirectional and also recharges the pack itself.
It resists water splashes (IPX5), dust and shocks, with a rubberised casing built for the outdoors. It is not, however, designed to be submerged.
Yes. At about 74 Wh, it stays under the 100 Wh cabin limit set by most airlines, with no special authorisation needed.
