静音 350 ワット ポータブル電源 288Wh リン酸鉄リチウムイオンバッテリー マーケットスタンド用電源 ピーク出力600W

A stall needs three things that a generator handles badly and a power bank handles well: quiet operation next to customers, no fumes under an awning, and enough outlets for lighting, a card terminal and a phone or tablet at the same time. PL350 supplies 350W continuously with 600W of peak headroom, weighs 4.15kg so it can be carried in with the stock, and recharges overnight from a 200W AC input in a little over two hours.

Built around a trading day

1. Lighting that lasts the whole session. LED strip and bulb loads in the 20W to 60W range draw a small fraction of the 288Wh bank, leaving capacity for the till and the card reader through a full market day.

2. Peak headroom for switching loads. Coffee grinders, small printers and refrigeration compressors pull a surge at start-up; the 600W peak window absorbs it without shutting the inverter down.

3. Silent, and safe under cover. No exhaust and no fuel means the unit can sit behind the counter inside a marquee, which most markets require and generators cannot satisfy.

Counters that need more than one outlet

Two USB-C ports, one of them 140W, keep a tablet-based POS system and a phone charged while the AC side runs lighting, and the 12.8V 10A DC socket can feed a small cooler or a display fridge directly. With 200W of AC charging the unit is back to full in roughly two and a half hours, which fits an overnight stop between market days, and a 240W solar panel covers multi-day events without mains access.

PL350 is packed in a colour box with foam inserts and an export carton, backed by a 3 year warranty, and available with private label branding for retail and rental fleets.

Factory and quality behind each PL350

PL350 is assembled at the SOUOP plant in Guangdong, where cell sorting, pack welding, BMS programming, inverter assembly and ageing tests are all handled on site rather than outsourced. The facility runs ISO 9001 quality management and BSCI social compliance audits and employs a dedicated reliability lab for drop, vibration and thermal cycling tests.

Every unit is cycled through charge, discharge, load and insulation checks before packing, and each pack carries a serial number tied to its cell batch, so a distributor can trace a warranty claim back to the production run. Certificates for CE, FCC, RoHS, PSE and UN38.3 transport testing are held on file and can be supplied with each order.

For buyers who need their own version, the outlet block, enclosure colour, silkscreen, manual language and packaging artwork can all be changed, and the BMS parameters can be re-tuned for a specific market. Standard production runs take 10 to 20 working days after payment, with samples available before an order is placed.
