I hadly used my Zendure super pro base 2000 and it broke. When i sended it back it took months before they replaced the product. When i needed the replaced one for the firts time it didnt work or charge. So they have sended me a broken product and now they say its out of warranty time. No replacement or repair service is offerd even at my cost. Its the worst thin i ever bought, a robery of money. The company should be sued!
