Solar Chargers 30,000mAh, LMS Portable Dual USB Solar Battery Charger External Battery Pack Phone Charger Power Bank with Flashlight for Smartphones Tablet Camera (Blue)

This portable battery charger is so much lighter than my other one. It is light enough carry in my backpack or purse without weighting it down! The dual USB ports are perfect for me and my husband. The flash light is pretty bright, better than I expected. I’m going to start leaving it on my car’s dashboard when I am parked in the sun so that it tops off the battery when I am not using it. BEST OF ALL – THE PRICE! ($22) Similar products sell for double and even triple! I’m thinking about buying more for holiday gifts.

I brought this solar portable charger for when I go on hikes or bike rides, however I am so glad I had not gotten a chance to take it with me. For one thing it took forever to charge my phone, the second thing it was big and bulky, and third & scary thing was it exploded this sickly sweet stinky stuff in my vehicle in my bag while I was taking a nap with the AC on. Needless to say I could not return it because as soon as it exploded it started getting really hot and I had to immediately dispose of it away from my vehicle into a non-flammable trash can, which also meant that I couldn't ship or mail it back for a refund (I totally would have sent it back if I could have) 😖😟

Absolutely no way this is 30000 mah. Used to charge devices, compared to my other 10k and 20k mah chargers, this thing is WAY underpowered. Just from the weight of it you can tell it is not legit. I am tempted to crack the case open because I almost guarantee this thing has an old 10k mah battery, or even worse. Total scam and waste of money.

This product hardly charges using solar power with a clear view of the sky with no obstructions and now hardly works are all. After 3 hours the 4 LED lights still didn't light up to show a charge. (LED LIGHTS NEAR CHARGER ARE GREEN WHEN CHARGING, less LED lights mean less charge and each are equivalent to 25% charge as there are 4)Charging with a 5v Samsung charger charges that unit overnight.Now it won't charge at all using either method. This this is not at all a reliable brand and the electronic circuitry within the unit is flawed.

I have galaxy 9+, got two of these. Going on trip and was hoping to replace a 21k mAh charger I had. When I got them, they were shockingly light compared to all the other charge bricks I've had. The LED light is great. I charge it up overnight. Next day my galaxy 9+ was at 50%, I plug it into the charger. When I checked, phone was fully charged, battery light was at 2 of 4....galaxy 9+ is a 3500 mAh battery. I've tried several times, I've tried iPad, galaxy tab, and other devices. The battery pack is good for 1 recharge. The solar recharge, in full sun, is slow as well. Even in my south facing deck didn't rechargein a full day of sun.

Tremendous life on the spare battery, charges quickly & it is compact.

I used my 1st power bank for my Samsung S6 and was able to fully charge my cp 3 times on a full charge. This was straight out of the box. The 2nd power bank was no fully charged out of the box even thought the LED showed full charge. Have not had a chance charge the power bank by solar yet so I have to withhold my opinion on this feature.

Cool concept - does not work very well. I have a Samsung Galaxy Note 9. My device is picky about what charger it deems acceptable. Slow charges a majority of the time. Also, the solor panels take a LONG time to charge the battery. It's better to just charge it using a micro USB. defeating the purpose.
