TACAMO® Solar Power Bank Portable Charger - IP67 Waterproof and Dustproof - TSA Compliant - for Backpacking and Camping - Dual USB Port, Fast Charging Battery Pack with 3-Mode Emergency Flashlight

I purchased two for camping, hurricane preparedness and travel use. The unit feels solid, good door covering the charge and USB ports. The lights are a nice feature especially if you need the unit in the dark and to plug in your device to it. The grips on the unit are decent and could use deeper grooves to keep things from sliding around. The keyring loop is a little flimsy and it comes with a small carabiner to attach to it.When I took it out out of the box the led lights lit up and it started charging from about 50% to full charge in direct sun in under two hours. The LEDs look great and are readable in direct Sun even with their small size.The unit does come with a charging cable USB to microUSB. I did not use it to initially charge the device so we will see how a slow sun charge versus direct charge impacts battery cycles and efficiency.One thing they can improve on is the compass extends beyond the corners of the devise case so it will get scratched pretty quickly and may not be readable if you really need it some time.The instruction book has been translated from another language to English so some phrases are a little frightening and nonsensical like "Please store the item far away from children". "Please stop to use the power bank once bulge or leakage phenomenon happens". I hope this unit does neither.I look forward to using this and having the solar functionality when electricity is unavailable. This will get used a bit alongside a mophie with the same capacity that I have had for two years. While it is not as sleek as the mophie it has more features at a third of the cost.I love supporting veteran-owned companies and know they have my back if the product doesn't live up to expectations or fails.

I received a special offer for this product from Titan Survival. I have purchased many survival products from Titan Survival and they are a first class business. I thoroughly tested this solar power bank and it meets all of the published specifications. I can find no exaggerated claims. The solar panel works but it is rated at 2 watts max so the actual power produced in a real-life usage situation will be much lower under actual variable lighting conditions. It will take days, not hours, to fully charge a depleted solar power bank using only the solar panel. This is true for all single-panel solar power banks.A BIG PLUS is the warranty. TACAMO products have a lifetime guarantee!Amazon has many suppliers who offer a 20000 mAh solar power bank version in the exact same package. My tests on a number of the "20000 mAh" solar power banks offered on Amazon have led me to believe they are, in my opinion, really just misrepresented 10000 mAh solar power banks. Same quality and same performance but they only perform like a 10000 mAh solar power bank. I have found a 5000 mAh battery weighs about 4 oz. A 10000 mAh battery weight 8 oz and a 20000 mAh battery weighs 16 oz. I have weighed 4 of the "20000" mAh and they all weigh 8 oz. I did weigh one 20000 solar power bank of a different design and it weighed in at 16 oz as expected.Update: The battery is rated at 10000 mAh at 3.71 volts or about 37 watt-hours. I tested the battery capacity by fully charging the charger and then subjecting it to a complete discharge for 6 hours at a 5 volt, 0.89 amp load until it ran out of power. My test results showed the battery produced a total of 27.1 watt-hours into the load. This represents 73% of the battery's rating and is very good. This test was repeated twice with similar results.The compass performance is questionable and I would not rely on it for true direction. Use a military-grade compass with sights instead.

I was looking for something to keep the phones going in a power outage. Although I haven’t been able to really put it through it’s paces, it works as advertised so far. It will charge using the solar panel and seems to hold a charge. It charged my phone fairly quickly. I haven’t found out how well it will handle the weather.

I was in the market for another Portable Power Bank when I came across this unit that combines a solar charger, compass, flashlight and battery backup into one small unit. The unit comes mostly charged and I was able to start using it immediately out of the box. It included a small carabiner to attach it to a bag, as well as a micro usb cord to charge it with. I charged up my Galaxy S9 from ~40% to 100% in less than 30 minutes and only took the unit down 1 bar of charge in doing so. After using it to charge my phone I placed the unit outside in direct sun to see if it would charge quickly through the solar panel, and it was fully charged 2-3 hours later when I went to check on it.I have not done any serious tests as far as output, charging time for the unit, charging time for phones etc., but I can tell you that it is a versatile tool that is going to go into my daily carry bag if for nothing else than the ability to charge my phone and battery backup without having to find an outlet.

Use for future camping/hiking. Dislike because it did not come with a Micro USB input cable to charge the unit.

Granted, I haven't had the chance to put it to serious tests yet, but so far, I'm impressed. My test round (starting with a full charge) managed to charge a battery powered radio and my tablet from low to full charge once, and my tablet a second time from about 10% to 50% before the power bank ran out of juice.Edit: After it sat unused in my emergency bag for over 6 months, I pulled it out with the intent of recharging it only to discover that it it was still showing nearly full power.

Checked it out about a month now for charging phone and a small solar backup lite with no issues. Compass is accurate. I have not tried to max out the 10000mAh or tested the IP67 ratings as yet, wont tempt fate til after the New Year lol. So far though as good. I will be taking it on a 2 week bushcraft /primitive winter camp in March so I will update my review then; though I am not expecting any issues.

I like how it shipped quickly and it serves it purpose for what I bout it for.
