Not used to charge phone fully yet, as bought as a standby. Will not adhere to a Samsung clearview case, needs to be a smooth non-textile surface, as indicated in description. Like the fact that it doesn't _feel_ sticky, yet adheres very soundly to back of phone. Simple to remove, no residue. Two issues. Why would manufacturer not supply a small (maybe silicone?) pouch for storage? Secondly, can extra sticky pads be purchased if required at a later date? Had a pouch and extra pad been supplied i would be over the moon with the product so far! Tip.... put a fresh piece of wide, clear parcel tape on when you are not using. Then when you peel it off to use, the pad is sticky again. Still wish it had a storage pouch...........

Unfortunately I had no idea it would shatter the back of my phone when trying to remove. Theoretically it's a good idea but realistically I'm super disappointed. Warnings should come with this I think as once it's on, it has to stay on. Therefore, couldn't fit the phone anywhere, not back in its case or in the holder in my car.

It will only give you a quarter of a full charge. It can be useful if you need that little bit extra charge to cover you for the day but honestly, you would be better buying a full on power bank than this.

After adjusting it to find the right spot to charge my Galaxy S9 it covered my fingerprint reader (located on the back), this makes unlocking the phone a little slower.It sticks very strongly to the phone so taking it off is a bit difficult, I hope this will improve as the sticky pad wears a little.Other than that it does exactly what it said it would do.

I fully charged the charger and then used it on my s10 which was on 22%Whilst using the phone scrolling through amazon and messaging a friend it took just under two hours to reach 49% before i became too concerned over how hot the charger and the phone were. The charger was on one light at this point.I wasnt too bothered with how fast it was charging especially since i was on the phone but i dont like how hot the charger got and before i took it off, my entire phone was hot - so much so the screen was uncomfortable to touch!!!Also when i managed to get the charger off, the sticky pad was torn in the middle. Torn or heat damaged. I dont know. it DID charge the phone and i bought it to use it as quick fix charge for the commute home before i leave work, with the convenience of not having to leave it plugged in.However i cannot recommend this product and would urge prospective buyers to spend a little more and buy from a reputable brand.

Charges quickly but will only give you 15-20% on an samsung s10+.Gets really hot and then bends out if shape

it worked but just got stuck and was hard to get off

It's okay but you will only get about 35 to 40% charge out of it on samsung s10 plus. It's okay as a emergency charger.
