How to choose Solar Panels, Chargers & Cables
These six listings are accessories that ALLWEI sells for its own power stations, so the first check is fit: which station does the listing name, and does your model match? The XY-100 panel names the PPS300 and PPS600, the 400W panel and the car charging cable name the PPS1200 and PPS2400, and the two AC adapters carry the codes SGR-PPS1200-2 and SGR-PPS2000-2, which do not match the station names on the other pages. The 12V 60A DC-DC charger names no station at all. Prices as listed on October 23, 2026 were $29.99 for the cable, $59.99 and $65 for the adapters, $159 for the 100W panel, $239 for the charger and from $429 for the 400W panel, or $839 for two.
For a solar panel, watts (W) are its rated peak output: 100W for the XY-100 and 400W for the larger panel. Only the XY-100 page gives the rest: 18V and 5.6A at maximum power, a 23.4V open-circuit voltage (the reading with nothing connected), a 6.27A short-circuit current, 23% cell efficiency, a DC5.5 x 2.1MM connector, and 7.9 lb folded to 615 x 560 x 35mm. Check those against the solar input limit on your station's own page. The 400W page gives no panel voltage, current, size or weight, because its spec block describes a LiFePO4 (lithium iron phosphate) battery. The charger page's lower sections describe a different product, so its 60A and 800W claims rest on seven feature bullets. The cable and adapter pages give no length, connectors or wattage.
All six are sold by ALLWEI at allweipower.com, which says it is run by ALLWEI Trading Inc. Shipping is free by ground carrier in the contiguous US, and a multi-item order may arrive in separate packages from different warehouses. Returns run 30 days from receipt for an unused item in its original packaging, with an RMA number from support; you pay return shipping unless it is a quality issue. Warranty terms differ. The cable and adapters carry 1 year when bought alone and share a main product's cover when ordered with one. The XY-100 is listed at 2 years plus 1 with registration, and the table labels that extra year 'Paid'. The warranty page does not name the charger or the 400W panel, so ask support.
Look elsewhere if you need a page that confirms compatibility or specs. Three pages are empty below the price, one carries a battery's spec block and one another product's, and the 400W page's FAQ mixes answers about a 100W panel and a '20ow' panel. The crossed-out prices on five of the six pages are the store's own comparison figures, with no source or date. We found no independent lab test of any ALLWEI product, and Trustpilot shows one review on an unclaimed profile.

Questions before you buy
How do I know which solar panel or charger fits my power station?
Start from the station names on the listing. The XY-100 names the PPS300 and PPS600 (its FAQ says 300W and 500W stations); the 400W panel names the PPS1200 and PPS2400 (FAQ: 1200W and 2000W stations); the car cable names the PPS1200 and PPS2400. The adapters carry the codes SGR-PPS1200-2 and SGR-PPS2000-2 and neither page says which station it fits. No page gives a compatibility table, so ask ALLWEI to confirm your model in writing.
What do the watts, volts and amps on a solar panel listing mean?
Watts (W) are the rated peak power: 100W for the XY-100, 400W for the other panel. Volts and amps describe that power. The XY-100 lists 18V and 5.6A at maximum power, a 23.4V open-circuit voltage and a 6.27A short-circuit current, with 23% cell efficiency. The 400W page lists none of these because its spec block describes a battery. Compare the figures with the solar input limit on your station's page.
What does a DC-DC battery charger with MPPT do?
ALLWEI's 12V 60A charger is described as moving power from a vehicle alternator or solar panels into a 12V battery, up to 60A and 800W input, with a built-in MPPT (maximum power point tracking) controller. The 99.5% tracking and 97% peak conversion figures are the page's own bullet claims. The page has no spec table or input voltage range, and its title names battery types LFP (lithium iron phosphate), AGM, GEL and FLA.
Are these solar panels waterproof?
The pages are not clear. The XY-100 page calls the panel IP68 water-resistant against splashing yet says not to place it in rain or soak it for long, and to keep the junction box dry. The 400W page makes an IP68 water-resistance statement that names no wattage. We found no rating document for either panel.
What are the shipping, return and warranty terms for ALLWEI accessories?
Ground shipping is free in the contiguous US, 3 to 7 business days after 1 to 2 days to ship. Returns run 30 days from receipt, unused and in the original packaging, with an RMA number; you pay return shipping unless it is a quality issue. The cable and adapters carry 1 year when bought alone, the XY-100 is listed at 2 years plus 1 with registration, and the charger and 400W panel are not named on the warranty page.
