The Shargeek 140 is the latest in Sharge's line of high-tech, high-speed power banks. The 20,000mAh accessory debuted as a crowdfunding campaign reward, and also as a hybrid of two of its OEM's earlier creations. Is the 140 more than the sum of its cyberpunk parts?https://www.notebookcheck.net/Sharge-Shargeek-140-power-bank-hands-on-review-Matte-black-endurance.849928.0.html
lots of complains about shargeek charging issues. Not recommended to buy.
I bought a sharge charger which didn't work from the start. they will not refund or replace. their website recommends asking your credit card company or bank for a refund. check online review before buying - some have been told to return faulty goods they must use a postal service that costs twice what the goods cost. they are a scam.
