I bought these last time they were up. They’re kinda… not good. For my phone at least, they only charge for about 10 minutes at a time, so you have to keep turning the battery pack back on, which means they’re worthless if you have a job which makes you leave your phone in a locker during your shift
Reviews on Amazon say the built in cords have a thick plastic portion around the plug which kept them from working with many popular phone cases. Just something to think about depending on your phone case.
When these were up I bought them and so far have been pretty great. It’s not a lot but it’s small. I like having the built in cable and they are cheap. One of them squeeks which is my complaint. Probably will toss that one.
ok, can someone explain what these are to me. Are they power banks that only charge for a few minutes or something? And 2 are the android phone types and only one works with my iPhone? Am I understanding?
I bought a stack last time, and although they don’t hold much, they deliver that charge as fast as the wall charger. When my S5 is about out, one of these skinny little power banks brings it to 60%. Two of them will bring it to full charge in about 30 minutes. And they have a tiny flashlight built in. I’m glad I bought them.
Bought a bunch last time…both lightning and micro. They take up no space and are great for travel. Give them away as gifts. People love them. Have a larger version from the same company that I keep in my luggage.
I got the 10 stack last time in MicroUSB because I have lightning and micro devices so itll be nice to have 1 lightning so I dont have to carry an adapter. Theyre not bad especially if you just need a little boost while you head out of the house at night. V thin so its easy to just plop into your pocket
I put all six that I bought into a single stack and measured the charging current. It was 1.0 amps while several were charging and dropped to cycling between 45 and 70 milliamps shortly after the blinking stopped. This is characteristic of some lithium battery chargers when they are at the tail end of the constant voltage part of the charging curve.
Eventually it became a steady 45milliamps. This is probably just the load from the LEDs. My set includes 3 with comparatively bright LEDs and 3 with dim LEDs. A single dim LED model draws 4 milliamps, while a bright one draws 12 milliamps.
3 out of 4 of my MicroUSB chargers have the annoying LEDs that are too bright for a bedroom.
