Power-Bank-Solar-Charger – 42800mAh Portable Charger,Solar Power Bank,External Battery Pack 5V3.1A Qc 3.0 Fast Charger Built-in Super Bright Flashlight (Deep Black)

Handy to have, but some drawbacks
I bought this in a rush as we had a power outage that would go for 4 days. It was mainly to keep our phones charging. It’s pretty hefty and looks tough. It charged our phones to full charge while the battery dropped 1 of 4 bars of its own charge.I like the fact that it can recharge both by AC outlet (you need a USB adapter plug) and solar energy.However, the solar panel won’t charge fast at all, even in full sunlight. It’ll take a whole day of full sunlight to charge 1 of 4 bars.Another issue, charging in full sunlight in scorching summer heat will heat up the battery pack. Since it’s a lithium battery, be very careful as it can ignite. We live in SE Texas, and sure enough it was very hot to the touch after I left it in the sun for 2 hours.Overall, it’s very handy to have for campers/hikers/preppers/survivalists etc. Even a slow solar charge beats not having any power at all.

This unit can charge multiple devices.
I really like the overall quality of this charger. It has multiple charging ports for a variety of different devices, such as cell phones,tablets,rechargeable flashlights,etc. I really like that you can plug it into an AC socket and charge when you have power to keep it ready for power outages, but can charge in the sunlight when there is no power. It has a nice led power display to show its current charge and a handy bright built in flash light also. I highly recommend for the price!

Large capacity battery and simultaneous charging of 2 devices.
Solar Power Bank Charger had 3 bars or 50-75 percent charge out of the box. It was used to charge a phone and tablet to get it down to 2 bars. Charged a Ipad Pro 10.5 from 40 percent to 100 percent and a Iphone SE3 from 60 percent to 100 percent. Unit was later set outside for a couple of hours in direct sunlight on a 22 degree afternoon. Not sure if 3 days worth of direct sun exposure would have increased the charge to a third bar. Maybe best to use the solar feature on a fully charged battery to keep it topped off. As for solar charging a smartphone, maybe an hour or two would be sufficient to get a 1 to 3 percent charge.Unit was later fully discharged and then charged with a fast charger. It was plugged into the fast charger at 7:00pm and left to fully charge throughout the night. By 5:00am, it was charged.This 42,800mAh device has some heft to it. Solar Power Bank Charger was set between a 21,000mAh Jump Starter and a Jackery 10,400mAh USB charger to compare its size to the others. That is an old Iphone 8 sitting next to the Solar Power Bank Charger in the picture.The flash light feature is adequate. I bought my mom the same device after trying mine out.1-21-24My Power-Bank-Solar-Charger suffered a 2 ft drop by accident onto a hard surface. Everything is still functioning but it now has something rattling inside of it. I question the shockproof and rigidness of this unit.5-02-24Some people are questioning the battery capacity of this Power-Bank-Solar-Charger. TOPDON or equivalent Battery Booster Jump Starter Pack might be a better choice. Some of them like the one in the picture come with a 12V Cigarette Lighter Socket Adapter. You can buy one for the TOPDON on Amazon. If you have cordless power tools, a USB charger that mates to your power tool battery would give you more battery capacitance options. Some of the multi-functional power adapters have a 12V 3 amp output and others have the option to connect a 12V Cigarette Lighter Socket Adapter to them.5-11-24Connected a KYY 15.6 inch portable monitor and a Roku Streaming Stick 4K to the Power-Bank-Solar-Charger to show off the portable monitor to my mom. She needs a portable monitor to travel with for her business. I only had the devices connected to the power bank for maybe 15 minutes. It managed to keep both devices powered. I am not sure for how long though.
