Solar Charger Power Bank Fast Charging - 30000mAh Portable Solar Phone Battery Panel Charger, QC3.0 Dual USB Port Battery Pack Charger for All Cell Phones & Electronic Devices (Orange)

I have bought 3 of these power banks and love each one. Two were gifts and they are still all in use years later. They are VERY DEPENDABLE!

Great idea but hard to charge both solar and electrical way.

Let's do some math based on the manual and info given to show the major flaws in this product.Solar cell is 5v manual says it has a watage out put of a peak 1.5 watts the battery pack is 30 000 milli amp hoursWe will convert the mah to amp hours by ÷1000 = 30AhNow we need amp out put of the charging rate so ohms law I= P/V or amps = wattage/ voltsI = 1.5 w/5v I = .3 amp output to battery.How long to charge in sun: Amp hours / Amps = time (hours) or 30Ah / .3A = 100 hoursIt will take 100 hours to charge the battery pack.Also noted in manual its ip7 rated but advises to keep away from water , dust , direct sunlightAnd only operate below 15c which isn't even room temperature.Also states it supports super fast charging confirmation on a s22 ultra with a normal charge time of 47 mins from complete dead with 33 wat transfer from an original super fast charger from Samsung type c to c , the battery pack will take almost hour and half to charge the phone from 50 % to full in 1.25 hours.The compass does not point north in case you were wondering as well.So to sum everything up it says it's ip7 rated which means it can be submerged but you shouldn't get it near anything or operate it in your house or you might cause damage to the device because it should be used between -20c and 15c , compass doesn't work , it takes 4.1 days to charge it with the solar panel and should be able to charge 6.179 s22 ultras and so far it's charged 2, 1 from 20% and 1 from 12% and the pack is at 1 bar solid and blinking 1 peehaps a damaged cell ? Idk will use it backpacking through BC mountains for the next 42 days but wont be relied on for emergencies.Clever marketing I will say though.

ONLY reason i gave it a 4 is because it doesn't charge so well unless it is in full sun outside. But if you charge it with a cord, lemme tell ya, it works very well and can charge my samsung s21+ to 100%. This one starts the second you plug it in. Most other battery packs take a min for it to register on the phone so to speak before it starts to charge the phone. Definitely recommend it but the solar part needs to be worked on to work better.

The media could not be loaded. The solar power bank came fully charged. Nice! I have had it constantly running this small automatic cat waterer that I set up for the hummingbirds on my front porch for 24 hours, in the shade most of that time and it still indicates a full charge. I checked the flashlight and it seems to be average, but if needed in an emergency, I’m sure it would be a welcome addition to have on hand and would undoubtedly last a good long time! Construction seems sturdy, and I like the touch of color so it can be easily found in a drawer or backpack.i plan to move this set up off the porch with a zip bag around the charger to protect from rain, as it may be waterproof when the door to the ports is secured, but certainly not when in use. I’m glad to have this on hand in case of an emergency! For $20 the piece of mind is well worth it!

Si bien es un producto que puede sacarte de un aprieto, no brinda una autonomía como se indica en la descripción.He tenido la oportunidad de probarlo durante una semana, dejo descargar mi celular para luego cargarlo con la batería externar, conclusión:- La batería logra cargar el celular una vez el celular al 100%, se descarga nuevamente el celular y la batería portátil logra cargarlo hasta el 29% y es allí cuando se agota la capacidad del cargador.- NO carga solar, lo intenté colocando el cargador a la luz del sol directa por algo más de 3 horas (Cielo despejado) al final la batería no es cargada y, por lo tanto, no hay energía para cargar mis dispositivos.En si no es un mal producto pero si debería ser más puntual en lo que puede hacer ya que realicé la compra con la esperanza de que sería tal cual la descripción.Doy 3 estrellas de 5

la carga no dura tanto pense que tendría el amperaje indicado,mejor compren un power bank sin panel solar

I use it for travel on my motorcycle camping trips and international travel. When I camp at sites without power, it charges my phone and other devices. I have found it will charge my phone 2x. It was indispensable while on a trip to rural Western Tanzania. The power at the sites we were at was highly variable, and the power blocks often didn't work. When power available, I charged this to extend the time my phone was working between working charging locations. I just purchased 2 more for more flexibility.
