Portable Charger, Solar Power Bank 30000mAh with 2 USB 5V 2.1A Outputs, Compact External Battery Pack for Cell Phone Tablet Charging, Outdoor Camping, Vacation

It's been approx. 10 days since receiving this product and I'm satisfied so far. It was 3/4 charged and I was able to charge my Revvl cell phone 3x before the pack drained. It charged my cell phone very rapidly compared to conventional charging, I'd say half the time. However, one downside is that it took a little over 24 hours to fully charge via USB (if completely drained), and over 24 hours of consistent sun to get to the first indicator light. I guess the recharging speed is expected based upon the mAh??Otherwise, it's a nifty device to have on hand and for traveling. Not too heavy or bulky.

I never write a review. But I had to on this because I’m using it right now and made me have to say something. I don’t know if I got an accidental test product where the battery lasts forever from NASA , but I bought this back in April 2024 and have used it +/- 30 times to charge my iPhone. Sometimes From 15% to 100%. It is fast. It is faster than gas station wall plug in chargers, way faster. I have plugged this in ONCE to recharge itself since April . How does it hold a charge so long! Months, and I’ll grab it out of my drawer and it’s still 4 full lights ready to go and charges my phone up so fast . You’d think after months in the drawer it would be dead. Nope. Ready to go. I have not tried the solar yet but at this rate we are going I bet it will be reasonable too. PS I have no idea who this company is, and not paid to write this, I’m just a person who bought this from Mississippi and had to say something because I’m nice and wanted to say thank you to whoever made this! So much out there is not good and trash but this actually works . I even wrote a review that I never do!

Good product. Sturdy and charges my devices fast. I can get a total cell phone charge from a fully charged battery pack. This is solar and wall charging, however I'm not sure how the solar charging works. I left the uncharged battery pack in direct sunlight all day (12 Hours) and it charged up just one bar out of 4. So either I'm doing something wrong, my device is defected or solar charging takes a very long time.

seems to work fine. My brother uses his all the time and says that the charge last for days.

Works as advertised

Discussion forums recommended a product like this for Disney because visitors use their phones and devices so much during the day. You'd think a Florida sun would help it work quickly.However, even when the charger seemed full, it was slow to pass that charge to other devices (like hearing aids or a phone). It was heavy, so not great for charging while on the move. More traditional power banks work better if you're trying to charge and use your device at the same time.I suspect it could be more helpful if you are hiking or camping.

I bought this over 16 months ago. I love it!. I leave it in the sunlight on my desk and it is always charged. During a trip to Scotland I used it to charge 3 phones at once on a long day trip and it never lost charging capabilities. My wife and I travel a lot, overseas, and many 2-4 day trips exploring parks. It comes in handy keeping our phones charged during the day no matter how much we use our phones. I have noticed over time phones lose battery time as they age. This charge will help immensely if you have that issue(I keep my phones longer than I should). I can't tell you how long it lasts because it has never run out of charge. I guess some day I will have to experiment with that. I would recommend buying the Minlu retractable charging cable. I like this because it will provide three types of ports for charging various phone brands. It is nice to have if your group has iPhone and androids.

Even though the capacity of the power bank is large, the Solar panels on the top side is nowhere near efficient enough to charge the power bank at all. I’ve left it in the sun days on end, and it was not able to charge even 1/4 dots that are displayed. I contacted support, but they quickly dismiss the problem, and even if you bought it a while ago, they are not willing to help with your issue at all. Do not buy.
