Review on MEGAWISE Car Battery Jump Starter - 1500A Peak 16800MAh Portable Power Pack For Up To 7L Gas Or 5L Diesel Engines, Dual USB Outputs, Auto Battery Booster [2021 Upgraded Model] by Ali Lariosa

Bought this over a year ago. This megawise worked very well, and helped many times to start my Jag XK. I had not used it for around 6 months, and when i took it out to use, realized that it did not work. I called their customer service, and they explained i needed to turn it on at least very month or so, however they would be delighted to replace it. 2 days later a new one came in the mail. HIGHLY RECOMMEND! Thanks guys.
