Bawofu 5V 2000mA Micro USB Power Supply Wall Charger AC/DC Adapter Universal Power Adapter

Works great for rechargeable batteries with 5v 2000ma input.

I can't speak of it in terms of longevity since it hasn't been long since I got it. But, that said, I am very pleased with this charger on several levels.MICRO-USB FIT: Often times I get chargers that have microUSBs that either are too short or too long or wobble in the ports. This one is just perfect. Fits snugly, and feels like this would be the original charger to my Samsung Galaxy cell phone.CHARGING SPEED: Fast. That's all I can say. It charges really fast.UTILITY: So far this has been a perfect fit for my Samsung phone, my Nokia Lumia phones, and my Amazon Kindle.This may be a generic charger, but it does as well as any brand name I've used. Will further update this when I've used it for a more extended period. But for now ...... a definite recommend.Hope this review was helpful.

did not work on the power pack, can use it for a replacement for a tablet.

I had to replace some old dying cords on a Bluetooth speaker and a disco light, and this cord charged the old oontz speaker better than the original cord

Not the longest cord, but it works very well for my purposes.

This is third adapterYou know.....usual Chinese device...low quality product. Previous two was not working at all!!!Update" They contacted me (Josephine) and offered me a bribe in forms of full refund if I remove my review above. I decided to give them a second chance, so I told them to send me another unit, free of charge for fair testing. They decide and tried to pry my phone number. I did not gave them my number, because they refuse to told me why they needed. After that, they told me phone number is needed for sending me replacement. That was pure lie, because item arrived anyway. I told them I do not like company who trying to lie to me. Then they start to be arrogant and threaten to report me to Amazon. I tested their new device and result is exact same as before. This adapter should deliver 5V DC, 2A on output. I'm using it to power Amazon Firestick 4k, and with my experience with all kind of adapters if output is lower that 6V DC 2A, Firestick 4k constantly rebooting itself. That's what is going exactly with this device. I will not buy anything from this company ever. This product is low quality junk. Do not buy it!!!

I do want to add that they replaced the original product very quickly. It came a day ahead of schedule. For this I give them a lot of credit. Unfortunately I can't use it for my headphones and I am leery of using it at all.
