EBL Portable Power Station 500W

its great but I should of bought another 1000 watt, can I use it as a trade in and get a little toward a 1000 watt?

Not very powerful and the fact you sell 200w solar with a machine that can only take in 105w

Customer service is terrible to deal with and the up sale you on the 200w solar and the eb500 can only take in 105w max
