Solar External Power Bank – 20,000mAh, Waterproof & Portable USB Charger

Left it on my car dashboard during work and came back to extra charge. Proper impressed with the solar function.

Thought solar would be gimmicky but it genuinely works. Kept devices charged for three days camping at Lake Taupo.

The carabiner clip is brilliant for clipping to your pack while tramping. Gets sun exposure and charges as you walk.

Week in the bush with this and my phone never died. Solar panels kept it ticking over nicely. LED light is handy too.

Skeptical about solar power banks but this one genuinely works. Left it on the dashboard and got decent charge. Waterproof seal is legit too.

Been chucking this in my work bag for months. Rubber coating still looks new and battery life hasn't dropped.

Power went out for three days and this kept our phones charged. Solar panels worked even on cloudy days.

Expected the solar to be useless but it actually works. Slow but steady. The 20,000mAh capacity is no joke either.

Five days on the Milford Track with this thing. Solar kept it topped up enough to keep GPS running the whole time.

No more dead phones at Coromandel beaches! The LED torch is surprisingly bright too.

Quality feels premium and the dual USB means I can charge my phone and headlamp at once. Worth every cent.

Used this on a week-long sailing trip around the Bay of Islands. Kept all our devices charged and the waterproof rating is legit.

Left it outside overnight in Auckland rain. Bone dry inside.

After the cyclone last year I wanted something reliable. This thing is built like a tank and the solar panels give real peace of mind.

Dropped it in a creek by accident - still works perfectly! Solar charging got me out of trouble when I forgot to charge it.

Been using this for months on hunting trips. The carabiner clip is genius for attaching to my pack. Charges everything multiple times.

Got this for power cuts and it's been a lifesaver. Heavy duty build quality.

20,000mAh lasted the whole weekend at Rhythm & Vines. Love that it's waterproof.

The solar panels actually work! Charged my phone twice while tramping in Fiordland. Waterproof coating held up in heavy rain.

Love the massive battery and dual USB ports. The little rubber port covers are a bit fiddly to open with wet hands.

20,000mAh goes the distance and waterproof rating is legit. The included USB cables feel a bit cheap though.

Does everything promised and build quality feels premium. The internal fan is a bit loud when fast charging though.

Works great once you figure it out. The manual is pretty basic and doesn't explain all the LED indicators properly.

Charges everything multiple times over which is mint. Only issue is the weight - definitely notice it in your pack.

Love the massive capacity and it's properly waterproof. Just wish the solar panels charged faster - takes a full day in good sun.

The USB charging is fast and the 20,000mAh lasts ages. Solar charging works but you need full sun for hours to see much difference.

Love the 20,000mAh capacity, charges my tablet and phone easily. Only downside is it's quite bulky for travel.

Dual USB ports are handy for charging two devices. Only gripe is the solar charging is pretty slow - better to charge it at home first.

Does charge things and seems pretty robust. Not blown away but it does what you'd expect for the price.

It's fine. Charges stuff. The solar panel thing is a bit of a novelty but whatever, it works when plugged into the wall.

Does what it says but nothing special. Solar bit is more of a gimmick really, takes forever to get any meaningful charge from it.
