Cargador portátil XTPower MP-50000 - Batería externa de alta capacidad con salida de 5 a 20 V, CC y USB, tecnología de carga de alta velocidad para portátiles, iPhone, iPad y Samsung

Worked with the "I" adapter from the Vktech Universal 28 DC Power 5.5x2.1mm Jack to 28 Plug Power Adapter set to provide 19.5V DC input required for HP Elitebook Folio 9470m, on the 19V DC output setting. Great and simple design, excited to use in the field. Given my current ultrabook's battery stores 3.4Ah at 19V = 64.6Wh, and this bank at 195Wh, that's three times the capacity! Any problems will report back.

If we still had a space shuttle...this baby would power it...its a plug and charge baby. solid, exactly as advertised. You get what you pay for, and this is a rock solid Power Bank. I charge everything overnight, and the next morning its a"no worries" deal. I have Windows Phone, Nokia, a Kindle HD, Vita, and an old work horse emachine computer. They barely make a dent in the available power. Thanks

Love it, lots of capacity. I just wish it charged up faster and had a 24v out setting. The DC out level has to be manually chosen so be careful. I fried a string of 12v lights when I forgot to lower the DC out after charging my laptop.

Awesome. Used for my laptop and usb fan while vacationing in Nigeria becuase you can't depend on stable electricity.

Powers my CPAP machine for 3 nights.
