A ADDTOP Solar Charger Power Bank - 25000mAh Fast Charging Bank with 4 Panels Solar Cell Phone Charger External Battery Pack for Phone Tablet Orange

This little beauty kept my phone with power for three days when my off grid electricity supply failed.Enough juice in the pack to charge my completely flat iPhone. Putting it out in the sun all day would charge it enough to top it up again.It does seem to absorb the sun like a sponge but it is difficult to tell how much it is charged as the wishy wash leds light system bleed onto the next light and in bright sunlight it is impossible to see. Why add a light? Seems everything comes with a light these days, you don’t need a light spend the money on better leds.My little gripes are trivial I got this as a solar charger and that it does to perfection, keep up the good work.

Now had this for almost three years, it’s a wonderful piece of kit. You can charge it either through its solar array or by micro usb. It has a high capacity battery so I’ve found it can charge a standard iPhone several times or an iPad once or twice depending on how charged it is. Takes about 8 hours to charge to max from nothing via cable, or in the best conditions a few days via solar. All of this of course depends on the plug you’re using to charge it from or how sunny it is. I personally love it, so handy to have something that has the capacity to charge your phone when you’ve forgotten to, or with a few hours in the sun, can at least give your phone a bit of a boost to get it through the day. It also never gets hot when charging for the mains which I think is a good thing. It’s a larger power bank which can fit in a big pocket. As for toughness/ durability, it feels very solid, would help if there was a clip on the back for it to be attached to a rack sac if you’re out on a walk but ultimately it is practical.

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.

Absolute rubbish! I bought this to go camping at a festival with. When it came, I fully charged it, having left it a couple of days and waiting until all the dots on the side were blue. The next day, I went away, and the following day, my son used it to charge his iPhone. One charge for his phone drained the entire thing! So I left it out in the blazing sunshine to use the solar panels to charge it up. The green light came on, showing it was charging. Went to use it to charge my phone and got nothing out of it. Luckily, the festival had charging packs we could hire. It's a good job I wasn't using it out in the mountains like I had planned to. Others may have had a good experience but I wouldn't leave this to chance anymore.

The solar pannels will take about 7 days of strong direct sunlight to fully charge the battery from empty. In my experience Its a fairly good battery to take camping, as the solar pannels do help extend lifespan of the battery. It is sturdy and has so far held up to being outdoor in -8C all day with nothing breaking. Whilst small and light enough to be throw in any day pack, it's too large for most pockets. It can fit in the average Jeans front pocket but not comfortably and its size seems large for its charge capacity. I have a smaller 10000mAh battery that performs as well if not better. The claimed 25,000mAh is a generous exageration. I can rely on it to fully charged my phone twice before running empty and the charge indicator lights are inaccurate and vague. The charge indicator lights are also dim and impossible to see on a bright day. That seems like a big oversight for a product that relies on sunlight for its main selling point.In short, it works. But its now my backup to better products.

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.

This is my second purchase - the first one I bought earlier this summer and used it extensively for all my camping, travel trips. As I have Samsung 9+ phone with battery needing to charge 1 or even 2x a day, this bank has been a real live saver - and not just out there in the wilderness, but also at work running around when it's so much easier to just plug your phone into this in your handbag rather then searching for a socket somewhere.The charging time is long but I keep it open most of the times so it's always full. All 4 solar power plates works great. I can charge my phone multiple times on one charge. The only problem I encountered is that during hot summer days, the plates got quite hot when charging resulting in the fabric around the edges melting away. Not a big issue, it looks a bit untidy but still works a treat. Now I purchased a second one for my niece - may need to be back for more as more friends & families now want one too. Great idea and a great quality power bank.100% recommend to all

Recensione 2022. È con me da 4 anni, la porta USB per ricaricare si è rotta, ma sotto il sole si ricarica ancora molto bene, la durata della batteria è scesa della metà, ma una ricarica e mezzo al telefono riesco a farla egregiamente. Ottimo prodotto, meglio una porta USB di tipo CDue anni che lo ho, acquistato per lunghi viaggi in moto e funziona ancora. Le celle caricano con pazienza, sotto il sole diretto per 4-5 ore si caricano due tacche. Molto valido

Not charging after 3 months of purchase.

Bateria pojemna, można swobodnie załadować dwa prądożerne xiaomi. Na pełnym słońcu ładuje się do około 80% w ciągu dnia. Optymalny zakup.

Super contento, camperizo el coche con mi pareja y me lo llevo para cargar el movil. Si este no lo utilizas mucho te da de sobra y si no, lo pones a cargar al sol. Tarda en cargar solarmente bastante (1 dia para casi completo) pero te hace la funcion para un par de dias.

Habitant dans le sud de la France, donc avec un niveau d'ensoleillement élevé, elle est un peu longue à charger. Seulement un point de luminosité par jour. C'est peu si l'on en à besoin rapidement. Mais sinon elle a l'air costaud. Pas conseillée pour les rando (ce qui était mon but au départ) car elle est assez lourde je trouve mais elle m'accompagne en voyageJe recommande, à moins de trouver une autre qui recharge plus rapidement
