What a great product! This small but powerful power station works great. It's super easy to use and comes with all cords and adapters you'll need. It came partially charged (55%) and we charged it fully before using it. The bundle with the solar panel charging kit is a great value. It's a great complimentary backup power supply to our larger Wattbricks Power Station. Bonus...this small one is airline approved!

Takes a long time to charge. Charge doesn't last long.

It works

Great product, bought this for my father's birthday, and he loved it. How the machine shows how much energy it's taking from the solar panel is really advanced and it's a great product for what my father will use it for. He loves to go camping so I'm sure this will be perfect in charging his batteries, lamps, and all those sorts of equipment

I just purchased it from my club, right out of the box it showed 54% charge then I plugged the solar panel pointing to direct sunlight and it says 40 hours until fully charged! From 54% to 100% takes 40 hours! I'll return this the very next time I go to the store.

works great on my night stand during the evening and night to run my lamp, charge my phone and charge my fitbit. on my way out the door in the morning if it needs to be charged I set out the solar panel and get it charged right up for when I get home it's ready to go again! perfect for what I need.

It was worth the novelty to buy this on sale. For some reason everything mine does is in 17 watts. No matter what charger I plug in it charges at 17 watts. It discharges at 17 watts and even the solar panel, in direct sunlight outputs 17 watts. I even plugged the panel into a different battery pack and it showed 17 watts.

Nice battery pack, but instructions do not mention anything about requiring the use of "trigger cables" or "power delivery cables" to get voltages other than 5 volts from the USB ports. Once you have one of these cables, the adjustable voltage type, then the voltages listed will work.

I purchased this combination power bank and solar panel at the beginning of December and have completed numerous usages to determine a fair review. I have lots of devices that are powered via USB and am constantly trying out different power banks to use with these products. I'm rating this item as two stars due to the fact that the power bank does hold a charge and works well with a variety of devices. It will fast charge your iPhone, Android, and laptops. However, it will only provide your cell phone with one full charge and may have enough left over to give a quarter or if your lucky a half charge more. To charge a laptop, it may give one full charge depending on the model, but will be completely depleted after. If your wanting to just have extra power for your cell phones, there are smaller options at half the price that will charge your phones two and a half times to three times before depletion. And for the same price (though without a solar panel), you can get power banks that will charge your laptops twice and have a small amount of juice left. This power bank has been a big disappointment, especially since it is carried by Sam's Club, which I would have expected to have partnered with a better product (I doubt any testing was done before placing this brand in their stores). Now as for the solar panel, I have several and small panels like the one included, really are a toss up. I have purchased good ones and terrible ones, often there is no in between. Unfortunately, this solar panel is not very good. It will charge the included power bank, but has to be carefully adjusted to gain the optimum angle of sun and due to this, it can't just be placed and returned to later expecting a full charge. Honestly, most solar panels in this size range are going to be the same, needing constant adjustment, however there are a good number out there that provide an even charge with low sunlight levels, but this panel is not in that category. It is nice though to always have a secondary method to charge your power bank for later use, and for my purposes, which is hiking and camping, any power is better than no power. I was excited to see this item at my local Sam's Club and it was discounted, but even at the sale price, I can't recommend when there are so many better options out there at half the price. I can't justify charging this unit all day in the sun to only provide one and a half charges at most. There are power banks more portable in size and weight, and provide more additional charges, which is the whole point of a power bank, I'd also like to point out the units boxed advertising as being misleading, from the size of the box to the images and text. I hope the review is helpful in selecting a power bank and in conclusion this unit is not adequate at the current price for personal use and definitely not as back up for a household to recharge cell phones during outages or camping.
