It is a genuine second path alongside the mains, most useful for travel and for emergency top-ups.<\/p>\nWhat sets the recharge time?<\/h3>\n The charging power, the usable capacity, and the taper at the end of the charge.<\/strong> A lithium pack accepts full current only up to roughly 80% state of charge, so comparing two stations by peak charging wattage alone is misleading \u2014 and a charger that cannot sustain its rating lengthens the number you quoted.<\/p>\nWhich DC connector should a station use?<\/h3>\n It depends on the current and the product, but the important thing is to specify it by part number, current rating and polarity.<\/strong> Common options include the 7.4 x 5.0 mm barrel, 5.5 x 2.1 mm barrel, XT60 and Anderson-style connectors, and two similar-looking types can mate badly.<\/p>\nIs solar charging the same as a power supply?<\/h3>\n No \u2014 a solar input needs a maximum power point tracker, which is a converter with a tracking algorithm operating from a variable DC source.<\/strong> That is a different product from an AC-DC adapter and normally a different supplier.<\/p>\nWhy is car charging so much slower?<\/h3>\n Because a vehicle socket cannot deliver the power a mains input can, and the cable and socket are often the limit.<\/strong> It is a top-up path rather than a fast charge, and describing it that way in the manual prevents disappointed reviews.<\/p>\nDo you make the built-in chargers fitted to larger stations?<\/h3>\n Yes, but they are scoped differently.<\/strong> Our standard external range covers 5W to 240W, which includes the adapter class and the high-power USB-C path. A built-in charger in the several-hundred-watt class is a different architecture with its own certification and thermal validation, so it is engineered and quoted per project rather than priced from a catalogue. Tell us the pack voltage, the charge current and the target charge time, and we will confirm which of the two your requirement is.<\/p>\nWhat MOQ and lead time apply for station chargers?<\/h3>\n From 200 pcs per model at Paiyi Power, with samples in about a week and first production 5\u20136 weeks after sample approval.<\/strong> We design to the PD 3.2 specification including SPR AVS and do not claim USB-IF certification or a TID; certification status varies by SKU and batch.<\/p>\n
