Warranty ignored – product failed and support stopped responding
I bought a UTRAI JS-5 jump starter because it advertised a 2-year warranty, long standby time, and the ability to reliably boost a vehicle. The unit I received is essentially unusable. It shows fully charged, but after inflating a tire only 3–5 PSI, the battery drops to one bar and it no longer has enough power to jump start anything. It also loses charge extremely fast even when stored indoors, sometimes showing low battery after only 1–2 weeks unused. I contacted support and requested a warranty replacement. I received one reply asking for photos/video, but after clearly requesting a replacement under the advertised warranty, they stopped responding entirely. In my experience, the warranty advertised on the product listing was not honored. I would not recommend relying on this company for an emergency device.
