Customer Ratings & Reviews

I use it for work so I need to depend on it's performance. Yes, it is a bit smaller on remaining power compared to conventional batteries due to the charger USB end, but still much more convenient to charge on the road. Charging speed is quite good, only a couple of hours.

I purchased a pack of AAA and AA batteries, and I would recommend this item. Easy charge via USB. I'd rather use this than the rechargeable type batteries.

The output is 1.5VDC. Easy to charge using a USB port. I will start using this battery for all my employees.

It's been 2 month now and still 100% satisfied with the purchase. Use to power wireless keyboard and mouse on my Mac instead of regular batteries.

Charged quickly for the 1st time use. Works fine. Good price. I like charging it from an USB port. I think I will get another pack when it is on sale.

Though I have just begun using these they seem to work fine. Hold a good charge. I bought these at BB deal of day. Keep a watch and buy them on sale.

Had little hope for these batteries but at full charge they lasted in my xbox one controller for about 3 weeks of semi heavy use. Super happy with purchase and would recommend these to anyone

we haven't seen how long they last yet, but the idea of charging them in the usb is great and the charge didn't take very long at all.

great idea. recharge your battery while playing on laptop or computer. would recommend getting a surge protector with usb charging option.

I have bough big name batteries that lasted only a couple months, these are still in use years later.

it is great for handheld games so while one set of rechargeable batteries are in the game ther other set is charging

Never worry about my xbox controller. Two in charge and two in it. Amazing

These are long lasting after full recharge. They recharge quickly using USB wall charger.

Love the product, so does my colleague likes it. Looks like I will not need to buy battery for a long time.

I am glad that I bought these batteries they charge super fast and last a long time between charges!

These put out full power of regular batteries, unlike others. Charge in any usb port quickly.

Excellent batteries, I bought a couple of AA batteries and work well. I definitely recommend it.

Super easy to recharge. Lasted a month in a high use device before needing recharging.

This is a unique idea. USB recharge in 1 hour. Four battery chargers sometimes don't work or take several hours. Holds charge a long time in my Digital Camera.

This is a perfect solution for the geek on the go. Batteries I can charge anywhere.
