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:	Does it work with iPhone x
Answer:	Sure. The power bank is compatible with iPhone 6,and you will need your own Lightning cable.

And all Qi-enabled phones like iPhone XS/MAX/XR/X/8/8 Plus,Samsung Galaxy S9/S8/Note 9/Note 8/S7 will be charged.
Question:	Do you need direct sunlight or will it charge in daylight
Answer:	You can charge as long as there is light, but the stronger the light, the better the charging effect, and the charging effect under low light can be ignored. Laboratory tests have shown that charging efficiency is about 5V/1.5Aunder strong and stable sunlight. Because of the problem of energy conversion rate, it can be fully charged in about 40 hours (stable and violent sunlight). Solar charging is not recommended as a daily charging method. It is recommended to use a cable for daily charging.
Question:	Can the solar panels be deployed in a 1, 2 or 3 unfolded in the sun so you don't need to take up a lot of room having all 3 expanded at the same time

User questions & answers

Question:	Ok should the controller flash when hooked up to my car battery all the time which is the - then battery both flash is that normal
Answer:	The weak point in this system is the controller. I would unhook it and put it in the round file, order a Zamp controller and install it. You will get better readings on your daily collection of amps, battery voltage, and you can use it with LA, LiPo and AGM batteries by choosing the internal settings. No it shouldn't flash, I set mine on a shelf as an emergency back up and installed a Zamp 10 Amp. More expensive, but more quality and more amps to your battery.
Question:	gauge seems small for the wiring; will it heat up under load
Answer:	It is really meant for smaller items such as cell phones or a radio Or light . Remember, the panel is giving power to the device, not the other way around. The wires are designed to handle the sun power
Question:	Is the controller water proof

User questions & answers

Question:	Windshields are typically uv rated. Does this actually work through the windshield
Answer:	Yes
Question:	WIll it keep a 12v 9AmpH acid battery charged
Answer:	It really depends on the load on your battery. My Prius will drain the 12 V auxiliary battery in about 10 days. I connected the Solar charger to my battery and it has kept the battery charged for over a month during this lock down.
Question:	Does it work with Lithium Ion batteries
Answer:	From a Google search. It is important to note that trickle charging is not acceptable for lithium batteries. The Li-ion chemistry cannot accept an overcharge without causing damage to the cell, possibly plating out lithium metal and becoming hazardous. Float charging, however, is a useful option.
Question:	What does the led module gauge? is is showing the percentage of battery charge, or showing the percentage of power coming from the solar panel
Answer:	Dear friends,the led indicator shows the battery charge.

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.
