I bought these tips to replace previous ones that were showing some wear. I used the same cables I already had that worked with the tips I replaced. When I tried to charge my phone using these tips (I've tried quite a few of them) and my cables that I already had, I couldn't get more than 300mA charging speed as measured by an Android app called Ampere. It's very slow and the loading icon in my notifications doesn't even light up. I know they are rated for 2.4A and 5 volts, but I'm nowhere near that speed.
