BLAVOR Solar Charger with Foldable Panels, Outdoor Power Bank 18W Fast Charging, 20,000mAh Solar Powered Charger with Camping Light/Flashlight/Compass Type C USB Charger 3 Outputs/Dual Inputs (Black)

This is a handy power pack that tries to be all things to all people. A compass, a camping light, and a mini flash/strobe light are all included, as well as USB power. It's tough, and the solar panels attached to it can be folded and secured with a push of a button. Unlike many of the less expensive solar power packs on the market, this one works with USB devices. C Maximum power output of 18 watts. Here's how I feel about it: br>br> Design: br>br> I think this item is well-designed, and they've made good use of the available space to keep it from being too bulky while still being rugged enough to withstand bumps on the road. The ports are nicely tucked inside a rubber cover so you don't have to worry about them getting wet when it's on your backpack and it's raining outside (it comes with a carabiner clip with a keychain ring to attach it to both the unit and your backpack - see below). (Please see the illustration). br>br>Ports - If you're looking for a unique way to express yourself, try using the words "innovative They support a variety of charging protocols on the USB ports, including: 5V/2 Apple Samsung 5V/2A, BC DCP 5V/1, 4A, Samsung 5V/2A, 4A, Samsung 5V/2A, 4A, Samsung 5V/2A 5A, QC2 5/9/12V, QC3, FCP, MTKPE 1. 5A, QC2 5/9/12V, QC3, FCP, MTKPE 1. 1 PE2. Despite the fact that one of the ports is labeled blue, the black one also supports QC2/3 (the ports are identical). However, only one port can be used at a time for quick charge based protocols to engage; otherwise, both ports would only be available at 5v (due to the fact that the charging circuitry on the USB ports is shared). br>br>The USB-C port is bidirectional. The PD3 protocol is supported by the C port. 0 PDOs at 5V, 9V, and 12V at 2. 4A/2. 0A/1. 5A, to be precise. It also works with Apple/2. BC DCP 5V/1, 4A, and 4A. 5A. This is convenient because most battery packs in this price range only have a dummy USB port. Google Nexus devices will not be able to charge beyond 5v if they use a C port that operates at 5v only. Having PD takes care of the problem. br>br>Be aware that the ports are tucked inside the rubber cover, so there isn't much room for direct plug-in. in USB devices with a large size You might need a USB extension or a right-angle adapter in those cases. In order for the plug to fit properly, you'll need an angle adapter. Most devices, on the other hand, connect via a standard USB cable, so this shouldn't be an issue (as you can see, I had to plug one tester on top of another because the second tester was a little too wide to fit into the rubber casing's mouth). br>br>Charging is a term that is used to describe the process of charging something. You can charge the device using either the Micro-USB port or the USB port. The USB port or the USB-C port is a type of USB port that connects If you're using the Micro-USB port, you'll need to connect it to the C port You can only use 5v/2 from a USB port. Unless your chargers support the Huawei FCP 9v protocol, which is 4A (though the battery pack usually charges at around 2). 7A or more if your charger has good voltage regulation and maintains a high voltage). Although pure QC2/3 chargers will not trigger 9v charging, most chargers made in China to support QC2 also support FCP. This is also true when using a USB-based device. Although the battery pack would request PD @ 9v as well as FCP if it were available, the battery pack would use the C port. The amperage is limited to 2A @ 18W when charging at 9v. Maximum Discharging Current - br>br>maximum discharge current - br>br>maximum discharge current - br>br>max I got 5V/3A, 9V/2A, and 12V/1 when I tested the maximum current at the various voltage levels offered by this battery pack without significant voltage losses. 5A. Except for the 5V/2, which I was able to exceed, this is pretty much within the stated specifications. Up until the 3A mark, the 4A rating was slightly higher. br>br>Voltages at which the load is applied - The voltages were measured at 5 volts when no load was applied. 08v/9. 12v/12. 11v. This is advantageous because they were previously set a little higher to account for cable resistance. The battery pack, as can be seen, was able to maintain a very stable voltage even when loaded (4. 97 volts, 3 amps, and an output of 8. 92v/2. 06A, 12. 01v/1. 51A). br>br>Br>Br>Br>Br>Br>Br>Br>Br>Br>Br> As you can see in the photos I've attached with the dark kitchen, the flashlight in front of you does a pretty good job of illuminating the path ahead of you. The small flashlight was directional, which meant it only illuminated the area directly in front of you, not all around you. The camping light, on the other hand, is much brighter, and when I first turned it on, I thought to myself, wow! The kitchen appeared to be lit when set to high brightness, but it is only slightly dimmer when set to low/medium brightness (as shown in the photos). This makes it a great tool to keep in your car in case of an emergency or while working in a dark garage. br>br>Auto on/off: br>br>Auto on/off: br>br>Auto on/off After 30 seconds of low/no load (due to a drop in output voltage to 2 volts), the battery pack turns off. This means you won't have to manually turn on the battery pack to start charging anything you plug in because the device will detect it and restore power to the proper level. This is convenient, but it comes at a cost. on a battery backup br>br>Charging via USB passthrough: True passthrough charging is supported by this battery pack. If a 9v input source is already active, it disengages and defaults to a 5v source. The battery pack then charges itself while passing the 5v input from the charger to its output ports. Due to the true pass-through nature of the situation, The output voltage is now regulated by the voltage source (e. g. , a power supply) rather than the battery pack (e. g. , a power supply). charger). As a result, the output voltage is likely to fall to around 4. When the battery pack is charging at high currents from the source, the voltage drops to 5 volts. Adding device load while the battery pack is charging adds to the input current, and if you have a high-quality charging cable (e. g. , a USB-C to USB-C cable), you can add device load while the battery pack is charging. a USB cable with a length of one foot When the other device (the enclosed USB-C to C 5A cable) is plugged in, the current can reach 5v/3A. A to USB- C 2. The 0 cable charges at a rate of around 2. When I tested it, it was 2A). The battery pack also appears to have a safety feature that prevents the pass-through of information. due to a charger malfunction causing the voltage to rise too high. In this case, the battery pack appears to stop charging when the output port reaches around 5. 45 volts (using a charger with a voltage of around 6 volts) While charging at around 2 volts, the voltage is increased to 40 volts. 67A). This is a good safeguard against your device frying if the charger malfunctions and continues to provide 9v QC even when the battery pack does not request it. br>br>Capacity Testing br>br>Capacity Testing br>br>Capacity Testing b During the discharge test, the real capacity was estimated to be around 65. 04Wh at 5v/2 at?% efficiency 3A. Given the high current, this is a very efficient method. Charge at 5v/2, on the other hand. Around 94 was needed for 7A. Without any additional sunlight, 92Wh of energy (78% efficiency). I assume this is because the converter is less efficient at higher currents, but I'll be putting this in the back of my car to collect sunlight while it's out, so charging efficiency won't be an issue for me. Solar Charging: br>br> The solar indicator on the charger (the green light next to the battery status indicator) is extremely sensitive, turning on even in the smallest amount of sunlight. It's worth noting, however, that the panels as a whole can only produce 1. Under bright sunlight, 2A of current is produced (theoretically up to 6W). Assume the panels produce 82% of the theoretical maximum and another 80% of that energy is used to charge the battery, which means the panels are adding 3. Under extreme sunlight, 94W of power is delivered to the batteries.


Assuming the energy required is 25% more than the nominal capacity value (92. 5Wh), which equates to about 23. To fully charge the battery from empty to full, it will require 48 hours of direct sunlight. br>br>If you were to leave the battery pack in a sunny location without moving it for the entire day (assuming 5. Under these conditions (5 hours of direct sunlight), charging it would take slightly longer than 4 days. br>br>If you're on the move and switching between shady and sunny areas, you might only be exposed to intense sunlight (or equivalents of) for about 1. Approximately 5 hours. The time it takes to fully charge a depleted pack increases from 4 days to just over 2 weeks in this case. br>br>And, because cloudy days produce very little current (generally 5-minutes), 10% of the power generated in comparison to the power of intense sunlight power), you will have to wait for a long time for this to charge. If the average cloudy day yields approximately 8% of the power compared to a sunny day, that means 0. The total power output is 3152 watts, or 293. To fully charge, the battery requires 45 hours of equivalent light. Even if you get 7 hours of equivalent light, it will take more than 40 days to fully charge the battery pack. br>br>Now, this isn't to say that solar charging is useless; rather, you should expect the panels to supplement the energy provided by a charger while you're on the go, rather than completely replacing the need to charge the pack from the wall (unless you want to leave it in the sun for a few days). If you believe that simply placing this near a window on a cloudy day will allow you to charge your phone indefinitely due to the infinite potential of sunlight, you are likely purchasing the battery pack for the wrong reason. br>br>If I were to go camping with the battery pack and charge my OnePlus 6T fully once a day (it has a 13. 3V battery), it would take me about a week to charge it. 69Wh battery) and leave home with the battery pack fully charged, the battery pack would charge my phone a little bit over 4 times/days (assuming a charging efficiency of 88%). I'm going to assume I'll get one. During camping, 5 hours of direct sunlight increases the charging time to nearly 7 times/day. This means that if you charge your phone fully once a day while camping, this battery pack should last you about a week. Of course, your mileage may vary (depending on your phone specifications, whether you use the flashlight or camping lights, the sunlight intensity of where you are going, and so on). 12v trigger cable: br>br> You can use a QC DC trigger cable to activate the 12v output for powering small devices because this power pack supports QC2 12v mode. As you can see, I was able to charge some AA NiMH batteries using my 12v LiitoKala battery charger. During a power outage, however, this may be far more useful for powering things like a cable modem or a router. At 12 volts, most modems or wireless routers use about 6 watts each, so using a DC splitter with this trigger cable would allow you to power both the modem and the router while staying under the 18 watt limit. (Note that you cannot use two trigger cables at the same time because the battery pack will only drop to 5v if both ports are used at the same time. )br>br>Overall, this is an excellent battery pack for camping and emergency situations. Even when used inside the home, the camping light is bright and could be very useful. Even if you think of it as a bright solar light, this is a pretty good deal at around $50.

I chose to live in my car, and I needed a way to keep my tech life going while not draining my car battery all the time. I've had this power bank for almost four months and am very pleased with it. I got this one with my quickly processed refund because the last one I got without solar cells needed to be replaced in less than a month. I've used it to charge a variety of devices, including phones, Bluetooth headphones, and my vape and e-cigarette devices. Pens, and whatever else my friends require, are all charged. It has enough capacity to charge my 4500mAh Note, 3700mAh Pixel, and 3500mAh vape, and then charge one of them again before the powerbank requires another charge. It is a blessing in disguise. During the day, I charge the power bank, and at night, I charge my devices. br>br>Omg, we're talking about the night. It's great that there are two flashlights included. One is directional in front of it, and the one on the bottom is much brighter. The one on the bottom will light up from a distance of about 30 feet. It's about a quarter of the brightness of a vehicle headlight from the 2000s decade. This isn't the case with this newcomer. I've adopted a halogen hodgepodge (just kidding, halogens are awesome, and I'm envious that I don't have any). br>br>One of the most useful features of this power bank is that it can be used to charge other devices while it is charging. This system works with both solar and external charging sources at the same time. For example, if I'm chillin' at a park and my phone's battery is low, I'll put the power bank on my dashboard [Keep in mind that I live in the US Pacific Northwest, where the average temperature from Summer to Fall is not higher than 80°F (26°C)]. In addition, I'll connect the USB port on my DC inverter. To charge the power bank even faster, plug in a C charger. I can't use a usb micro and a usb-c at the same time because I can't use a usb-c and a usb-c at the same When I charge two USB type A female inputs at the same time (unless they both have extremely thin frames around the prong), I have two USB type A female inputs available to charge whatever else I need. br>br>Even though my car's windows are tinted, I can still get it to charge from the sun in the backseat. This thing has indicator lights that let you know when it's charging, and it's nice to see that even on cloudy days, the sun shines through and the solar cells pick it up - Even if it is at a slower pace than usual. br>br>It slid off the dash as I drove away many times. I used the carabineer clip to secure it to my dash mount, but I unclipped it and flung it somewhere, so it's gone. I'm pretty sure my clumsy family needs these. br>br>According to the instructions, it should be kept out of direct sunlight - My advice to you is to charge in the brightest amount of shade you can find and keep an eye on how the sun moves (one inch every eight minutes? If you must charge in direct sunlight, ensure that there is adequate, actual cooling in complete circulation around the device (for example, suspend the bank using bottle caps and turn on a fan and direct the air at the device). This will prevent it from overheating, requiring a repair or replacement that could have been avoided. br>br>Best of luck to my sun-seeking comrades.
