    I bought the power bank for my laptop Lenovo Y540 as it has small battery. Power bank charges other devices but doesn’t charge my laptop via 20V output. All the rest is accurate. I agreed that the seller return 28 euros as a compensation.

    Battery power. I still have not tried it for battery life. I bought specially for the Harman/Kardon go + Play column to listen infinitely in nature. Cord and adapter are suitable for her. Charges well. The battery is healthy of course and heavy. Not for everyday wear. But he’s not for that. In short, all the nichtyak with the goods. I advise everyone. But the seller, he did! Therefore, I waited for the goods for 2 weeks and then found only when I myself called the delivery service. The seller indicated the wrong phone number. Where did he get the idea? The site is correct.

    This product was received at the designated adress in the Netherlands within a week!

    I purchased it with the intent to hook it up to a projector in order to make it completely portable. The projector required 19v and 3A, so I was forced to use a wall charger. However, this powerbank seems to make the wall socket redundant! I was a bit hesitant at first, but it works like a charm! After 2,5 hours, it was on 2 lights out of the 4, and after another 2 hours, it was running on 1. I didn’t continue afterwards, since I didn’t want to completely drain the powerbank.
    The beamer (an Optoma ML750e) takes about 65w through the wall charger, so for it to go at least 4,5 hours on a single charge is not bad! The delivered dc wire is compatible with the Optoma.

    The only thing is that I need to keep the beamer and powerbank still. Moving it around too much causes the beamer to shut off.

    So far, it works very well! If there is anything, I will be sure to let the nice seller know, and post again!
