“Does the trick. Not taken it apart to see what voltage regulation hardware it's sporting, or done tests regarding the following to ascertain impact to output voltage but it seems to carry a warning label suggesting to avoid greater than 500mA/h input - which makes it unsuitable to pair with. say, my 2.0A/2.4A/3A USB3 battery bank. Will work in older generation USB sockets, which are more numerous - but most wall warts et al come in at least 1A and have done for some time. Packaging markings suggest there's an option that is rated for 1A input, that might be a more viable purchase.”
“Handy to put in your bag, ideal for using to charge my spinner11, happy with purchase can be used to charge on tv or computer also with a plug if required”
