Fantastic but if ki
This has been really handy to have. Definitely useful and works perfectly. Holds charge well so does a few charges of my phone. I tend to do a full charge from my car on my way to camping trips then top up using the sola

Took this camping a few times and on weekends out. I manage to charge iPhone 14 pro max 3 times aswel as vapes etc on a full charge, handy having the solar panels too on sunny days
Good build quality 10/10 overall
Used for a couple of years and works well. Primarily a big power bank with solar top up. Solar charging is very slow but with decent sunshine would probably keep a single phone going day in day out. Best off charged at home and then topped up off a car etc as and when whilst away. If you need to charge multiple gadgets off solar only then you’ll need a much bigger solar panel to feed electricity into this / directly into those gadgets. Nonetheless has proved robust. Solar charging works best in bright sunshine but modest temperatures otherwise whole block gets too hot and stops charging till it cools down (but probably similar issue on other products). Generally would recommend.

I got the power bank to help my son for events he will be on where he may not be able to charge his gadgets from a power supply for a while. the additional benefit of a solar top up should be handy!
We were surprised that the power bank didn’t give more than a couple of charges to his iPhone though, and I also tested this against a flat iPad and the power bank only managed one charge really before flat.
I checked with the supplier on this, and they gave me a good explanation that I hope is useful to share here. The power bank battery is a 3.7V 25000mAh battery, but to charge a phone etc. via USB it needs 5V, which means in current terms it is 18500mAh. Also there will be some inevitable loss from the charging too, so the effective capacity will be lower still. So something to keep in mind when you try and work out how long you can go without a re-charge of the power bank itself! Good piece of kit regardless…
Heavy
The solar panels only charge when in direct sun.
The bank doesn’t hold charge very well and it’s very heavy.
But I do take it wa liking and get it out whoever we stop for a rest or drinks.
I’m using this to charge various devices, including a Chromebook which uses a USB-C connector (not included with this device, but cheap and easily available). Like other solar powered chargers, it can’t be expected to charge while the device is turned on, but I’ve succeeded in both topping up a little and completely charging, though not the Chromebook so far. It needs to be charged from the mains about once every three months. It’s worked with a tablet, a smartphone and a Chromebook. I live about 53 north.
I got this for a solo kayaking expedition, paddling the whole of the river Thames from source to Thames barrier. It was a 10 day trip.
I didn’t have huge expectations of this when I got it, I just thought it would be something handy to have, but it was a game changer!
You have to charge it up fully from mains like a regular power bank. Don’t assume that sunlight will keep charging it up fully, it won’t. The solar side of it is more of a trickle charger to slow down the depletion. BUT, if you have devices plugged in and there is good light, the solar panels will charge them directly.
This means that when I go out on the kayak now, I have both my phone and a GoPro plugged into this which I strap to the front of the boat. This keeps both devices charged for as long as there is sunlight, and there will still be charge left in the power bank at the end of the day. Seriously, I can paddle and film all day long!
It’s also waterproof(ish) so it’s fine in the rain.
I was also using it at camp at night, so eventually was drawing down the battery. But only once on my whole trip did I have to stop and recharge from mains, which gave me a nice excuse to stop at a pub and treat myself to Sunday lunch anyway!
I really thought I was going to have to stop a lot more to charge stuff, so it was such a nice surprise that I could just keep moving and get on with my trip without being slowed down by stopping to charge all the time.
Can not recommend this enough.
First things first this is about the size of large smartphone that is 3cm thick so won’t fit in most jacket pockets but should fit in a deep coat pocket. Probably best in a back pack or bag. It is quite heavy that is because this device holds a lot of capacity for charging multiple devices.
The solar panels are great but you have to be realistic they are only 5W so to charge a large battery like this at 5W will potentially take 40 hours charge time from flat to fully charged. It’s nothing to do with a problem with the product it’s fundamental physics. So let’s be realistic you’d probably need 5 sunny days in a row to charge it from flat to fully charged bearing in mind you get hours of intermittent cloud. So with that said the solar panels in this configuration are ideal for topping up the battery, so say you use 25% charging devices over night you can potentially fully charge it during the next day if you get enough sunlight.
What options are there? Well you could theoretically get an additional flexible solar panel rated at 10W with a USB 5V output that could charge the power pack as well but you’d need to check the Amp ratings (this is 2A for this device so max power input is 5V x 2A gives 10W) that this power pack can take as an input. It would be a good additional option for people that would like almost a full charge from solar in one day.
So this is the way it works it takes a mains powered charger of 5V at 2A rating (10W) to charge a 20,000 mAh battery power bank 16 hours to charge from flat to fully charged, so using the ratios to get the equivalent for this power bank of the higher rating of 25,000 mAh you need 20 hours charge time from flat to fully charged. It’s just the physics of power banks so nothing about the manufacturer. So you can see with a 5W solar panel array you have limitations.
The theory not tested but plausible: Potentially we could charge by upping the power in theory if we use 10W additional solar array with USB output with a 2A limit (device max input through USB is 2A) we can reduce the charge time from 20 hours to around 15 hours as long as it is permissible to use inbuilt 5W solar + 10W solar array with regulated USB output. The theory is based on the condition that you can use the built in panels and the USB input charge port simultaneously I cannot see an advisory that says you cannot.
I hope this helps as this is a powerful battery bank with a solar option that tops up the charge really, the bottom line is that it’s best suited by design to full charge mains initially then when travelling keep topping it up through solar or look at expanding the solar array to get more solar power to speed up the process but note there is a maximum of 10W from an additional solar array if you need to charge full solar.
The unit flash light is pretty much as bright as a mobile phone light it’s NOT like the ultra bright light you get from say an Alien Scout head torch where you get clear visibility in pitch darkness for up to 100 ft. It’s enough light to read, find the key hole in a lock or read the electric meter.
Not quite what I was hoping for but amazing customer services.
Hard to know what to expect from this but so far, having had it in bright sunshine for most of a few days I have never seen any of the blue lights (showing each quarter of battery) filled by solar charging. It definitely gets some charge as I was draining it when charging my phone but despite very bright sun it doesn’t seem to charge the battery very well. I know it is a large battery (although questioning whether it really is lithium ion rather than something like NiMh) but the solar charging (I have the 4 panel version) seems pretty slow. I will do more thorough testing (like trying to solar charge battery over a period of days and also connecting to a power meter) but so far I am a bit disappointed. I guess you really need bigger panels for a decent amount of charging speed. 🙁
Update: so this definitely does charge much better in direct sunlight than through windows. Whilst it ended up not being quite what I was hoping for (wanting to be able to get enough charge to fully charge my phone each day but from the solar panels being indoors) my overall experience ended being a very positive one due to the amazing customer service. My questions were answered really quickly and every effort was made to resolve my concerns. I would definitely buy from the sellers again. 🙂
Superb performance, even on a very rainy weekend
I bought this charger because I spend a lot of time camping and attend festivals which are on rural sites with no mains power.
I road-tested the charger at a 4 day festival held on one of the wettest weekends on record, so I had low expectations about how well it would perform. I needn’t have worried. I charged the power bank from the mains supply at home before departure until it was at full capacity. During the festival I fastened the unit via its hanging loop to one of the poles on my tent and left it there for most of the time we were there. Despite some heavy showers and overcast skies in between, the trickle charge from solar was constant and returned the device to full capacity relatively quickly after each time I used it to recharge my devices. The capacity was superb. I recharged my Android phone from around 20% to 80% about 5 times during the 4 days we were on the campsite and also took my mp3 player from around 30% to full twice. The time it took to recharge my devices was not as fast as when on mains, but was still pretty impressive, and the unit’s ability to keep itself topped up to full using solar was very reassuring. It’s made a massive difference to my peace of mind about being able to stay in touch whilst away from mains power sources and although a bit weighty, its performance definitely justifies its inclusion in my walking rucksack and camping supplies bag. This might actually be my favourite thing to take camping from now on.
