User questions & answers

Question:	Will this charge two deep cycle battles at the same time
Answer:	I don't know where the 2 other comments came up with one amp output. Minimum is 5.1 amps with mttp controller. Still insufficient to fully charge deep cycle flooded battery with much load.
Question:	Are there any directions with this item? also, do i peel off the plastic coating? it is all bubbly like i should, but i am not sure
Answer:	No, there are not really any directions but it’s pretty simple to use. Yes, peel off the protective plastic layer. I know it looks like it is attached underneath the fabric but it comes pretty easily.
Question:	how long will it take with good sunlight to recharge a dead 12v automotive battery
Answer:	The right answer is: It won't. 5W is the absolute best these cheap panels will output, in reality you will only get about 1W during daylight hours, mostly due to thermal derating. The charge will be so minimal, that battery leakage at night will eliminate any small charge you get during the day.
Question:	Does this have a blocking diode
Answer:	I don't believe this panel has a blocking diode built in as CX wrote in 2018. Can seller confirm whether there is a blocking diode built into the panel? Thanks

User questions & answers

Question:	Have yet to see any solar battery pack this size actually charge to full in bright sunlight. Can owners confirm it charges to full and how long
Answer:	I have never let my power pack discharge to empty. My power pack has had 3 lights lit and it took 2 weeks before the 4th light became solid. The power pack is advertised as the solar panel is only meant to charge the power pack in an emergency.
Question:	Does the solar panel actually work or just for decoration? How do I know if it's charging the internal battery
Answer:	Green light comes on if it's receiving charge from solar, and the blue lights light up in sequence to tell you it's getting some sort of charge (similar to what they do when you charge from an AC source); as others have said, it may take 55 hours or more in the sun to fully charge from the sun, so not sure how much the solar is actually worth (many of us, this was the reason for buying). As others have answered to similar question, it appears that it can also direct charge from the sun if you attach a cable to your phone, so maybe in a true emergency you can get enough charge to make a call or something.
Question:	Can this unit be charged with a usb as well or just solar energy
Answer:	There are 2 ways for charging your power bank, you could use a cable to connect 2A output adapter and your power bank for power supply. You could also let the solar panel face the sun and it will charge automatically in strong sunlight condition. The first green indicator light on the top of power bank will light up when it's in solar charging. Thanks for your question.
Question:	How long does it take to be fully charged by sunlight
Answer:	From the manufacturer: "Since it’s solar output 180mA per hour we can measure the theoretical charging time for your reference: We test the solar charging in 25000 LUX sunlight intensity, we let the solar panel face the sun for 5 hours. 5 h X180mA=900mAh (also guarantee the same light intensity in 5 hours) In this way, it takes at least 11.11 hours to reach 2000mAh, then it will generate 1 bar of electric power for phone charging."

Sunway solar battery trickle charger maintains the 12 volt battery of car, truck, marine , motorcycles , tractors, ATVs, snowmobiles, boat or RV.

Why do I need a solar trickle charger?



Three reasons to own a Sunway Solar Battery Trickle Charger:

• Batteries Naturally Discharge - Automotive batteries naturally discharge when not in use.
• Vehicles have a small but constant battery drain - Modern vehicles have upwards of 30 body control modules (computers), alarm systems, immobilizers and lock monitoring. These units all consume electricity from the battery. That's why in a week or two with no or little vehicle use the battery can become discharged.
• Battery life is shortened if it is not kept charged - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Sulphation is the main cause of battery failure. That's why the auto battery easy goes to dead when vehicles are left standing for long periods.

Question:	can I use this for light in my barn
Answer:	You could if you connected it to a small 12v battery and used some of the 12 LED retrofit light kits they use for the interior of cars or an 12v led strip. I'd suggest maybe a 12v CCTV battery to make it affordable. Unless you are talking about large amounts of light, then you probably would be better off with some kind of pre-made solar light kit.
Question:	Does this unit have a charge profile controller for lead acid batteries, they prevent over charging & shut down the current as battery approaches 12v
Answer:	It has no controller. But if you charge small batteries, you need a controller. If you charge a large battery, you don't need a controller because its current is relatively small and it won't cause overcharging.

User questions & answers

Question:	Will the LED light shows up when the battery is fully charged
Answer:	No the light comes on when ever there is current available at the cigarette adapter. It will come on when plugged into the vehicle or when the sun is shining on the panel.
Question:	is this a mppt or pwm controller
Answer:	There is no Charge Cntroller. There are enough Cells in the Panel to reach 12.6 to 12.8 volts when not connected to a Battery. A full charged Battery will test at 12.6 volts. A partially depleted Battery, say it tested at 12.4 will be charged until the battery voltage reaches 12.6 to 12.8. This is better than having a Controller which could go bad or malfunction. With the Cells balanced to charge no more than 12.6 to 12.8 volts, its not possible for your Battery to overcharge. Also, the voltage the panel generates will not wale up your Vehicle's Modules which could be sensitive to voltages in excess of 12.8 volts. This is a good panel. On an overcast day with my tinted Windows it will still trickle charge my battery until fully topped off.
Question:	will this charger work for lithium batteries
Answer:	No, this solar panel does not work for lithium batteries. because lithium batteries need a stable voltage and currents, also require precise control of charging.
Question:	There's green light before connecting to car battery@ 11.92V. But charging stops and green light turns off upon connecting with correct polarity. Why
Answer:	This is a 14.4V solar panel, when the solar panel is facing the sunlight, it will light up, but if you connect it to a battery, and the battery is lower than 12.5V, the light will turn off, when the voltage of the battery is higher than 12.5V, the light of the solar panel will light up again.
