Eb 55 Absolutely rubbish
Power bank not as stated 2500 cycles lifepo4 cells . After a year capacity drop 40% after 2 years can charge only up to 60%. Avoid no matter how desperate you are to have power bank. think twice before buy. Got eb55 . Contacted customer service regarding my thoughts about capacity of power bank. Advised reset it . Doesn't help at all. I believe is better have car battery or rather this power bank. On campsite eb55 not able run over night small 40w cooler. Overpriced device and now capacity is half . Shocking ... Just done only about 800 charging cycles. They claim 2500 cycles
