5 reviews for Custom Solar Power Bank – 4000 mAh

  1. Henry B

    I really like the look of these solar power packs but I am less impressed with their performance. It seems to take quite a while to charge them up in the sun and after that they will last for a while but not as long as I had hoped. I need to try charging them under artificial light to see if that is better. So far I think this product deserves 3 stars.

    The proof of the pudding and all that… I offered these to specific clients as a gift and they were overjoyed. I am very happy that I chose these solar banks and recommend them to anyone who wants to make a lasting impression.

    These are the words of our customers and not us. The quality of this product is excellent for outdoor mobile users and the print quality is also good too.

  4. Betty Applegate

    I went for a small batch of these to give away as gifts to our highest spending and most loyal customers. The reaction from them was incredible. They all thanked me so much and told me that a solar power pack would be very useful for them.

    These are not cheap but I wanted to impress our clients with a quality gift. Some say that they are not the most powerful at recharging, which is a bit annoying. Most are very satisfied with the product though.
