What does the UN38.3 1.2m drop test verify for the X5PRO?

The 1.2m drop test confirms that the outer packaging of the X5PRO Jump Starter with Air Compressor can withstand a free-fall impact from 1.2 metres in six orientations (top, bottom, side, front, edge, and corner) without damaging the internal lithium battery cells, without allowing battery-to-battery contact or short-circuit, and without releasing any contents from the package.

Why is UN38.3 compliance required for shipping the X5PRO?

The X5PRO contains a lithium battery (14.8V, 1500mAh, 22.2Wh), which is classified as a dangerous good under international transport regulations. UN38.3 compliance is mandatory for air freight (IATA), sea freight (IMDG Code), and road/rail transport to ensure safe handling and protect against fire or chemical hazard risks during transit.

Who conducted the drop test and is Waltek an accredited laboratory?

The test was conducted by Waltek Testing Group Co., Ltd., based in Dongguan, Guangdong, China. Report No. WTH25D12334288B002 is signed by the tester Jason Zhen, reviewer Jack Chen, and approving authority Deval Qin, and is valid only when bearing the official company seal and accreditation recognition stamp.

How many units were packed per carton and what were the packaging dimensions tested?

Each outer A=A carton contained 10 units of the X5PRO. The carton dimensions were 435 × 220 × 430 mm with a gross weight of 14.8 kg. The total net battery weight per carton was 8.25 kg. Each unit was individually packed in an inner cardboard box before being placed in the outer carton.
