I generally avoid anything that doesn&#x27;t have legitimate safety certifications: UL, ETL, TUV, etc.  (&quot;CE&quot; as printed on random imported crap seems to mean nothing in particular.)<p>Also, you can usually count on actual, non-counterfeit chargers from well-respected phone and tablet vendors being just fine.  I&#x27;ve never thrown out an old USB charger from an iphone, samsung, motorola, asus, just put them in a box for possible later use :)
