I bought this item for a test. All of my rechargeable AA batteries are just 1.2V so they do not fit in types of equipment needed more than 2 batteries. So the first issue, I measured the voltage and it is 1.5+V a shown on the first photo. Second, I wanted to know the duration. I took a normal bulb, 1 Watt and started to measure the time it lights. I switched it 13:19 on and the light went off 14:51 which means 1,5 hours. Sorry, this does not fit to the advertised 1250 mAh data. Using a 1 Watt bulb on a Voltage of 1,5 results 0,666 A = 666 mA. Two batteries with 1250 mAh must light (2500/666)= 3,75 hours if the capacity is valid. 1,5 hours in real time are less than a half. This means it will not serve energy consuming devices like non-LED bulbs/flashlights or toys, etc according to my opinion. Now I put them into my Logitech cordless mouse, we'll see how it performs there. The normal batteries lasted 1,4 years never switched off so I'll be able to compare. Before the test, I let the batteries empty. Loading will show a nice red light, full loaded even a green one. You get a very short Micro USB charging cable and a Micro-to-C-Type adapter too. So you can use it as a power bank for USB C-Type phones too. This (using as a power bank) I did not test, although the small and light batteries could be a nice emergency help. My overall rating common 4 stars in all three categories.

Son como la imagen, aún no he tenido tiempo de probarlas. Vinieron muy bien empaquetadas.
