    This is a nice case for 4pcs of 18650 unprotected cells it can easili recharge your phone but even the laptop or tablet or whatever. Only downside is that you can use just 15W of output power for the round 5.5mm connector. It is a good choice for easy set up of a powerbank. Thums up.

    Pros: USB Port delivers 5V and i tested it up to 3A! Amazing! The output port is 5.5 x 2.1 mm and is pre set to 12V. Can be adjusted within the box up to 24V. I use the 12V for my little chinese power amp (last photo) which works great! Cons: Input is 3.5 x 1.35 mm and you must use a stable 8.4V power supply to recharge the box. There is no charging circuit in the box so if you exceed 8.4V you will blow up your batteries. There are also no lamps glowing when in charging mode!

    Didn't come with any information or instructions and no cables. The product I received looks different from the one in the photos but seems to be essentially the same thing. In the description it says there is a thing you can turn inside the change the voltage from 8 to 24 volts but I can't see that myself. Have charged up some batteries and put them inside and will give it a test shortly.

    Fantastic product! It works awesome! I use it for my self-made external monitor and it runs more than 4 hours! That's great!

    Works properly, but the very poor appearance.

    Bon produit. Par défaut la sortie est en 12V. Avec un petit tournevis il est possible de descendre jusqu'à 8,4V. Attention pour recharger les batteries vous avez besoin d'un chargeur en 8,4 v.
