Gravity, hand pump or 12 V: the water has to move somehow · review
Aqualand 20 litre solar gravity bag with head and hose review
A gravity solar bag: fill 20 litres, hang it in the sun and let height do the work — with no hose length, no weight and no shower duration published anywhere.
The bottom line Twenty litres, a hose and gravity. Everything that matters about how it behaves is left to you to find out.
What this listing puts on record
A 20 litre black water bag with a shower head and a hose, warmed by sunlight and stated to need no electricity. There is a hand-held head on a flexible hose said to give an even jet, a carry handle, and the bag is described as quick to fill and easy to hang.
What kind of shower this is
A gravity bag. There is no pump and nothing to charge. You fill it, you hang it, and the pressure is whatever the height gives you. That makes the hanging point the whole mechanism, and it means a full bag has 20 kg of water in it before you count anything else.
What the listing omits
No hose length. Where the head can reach depends entirely on it, and it is never measured.
No shut-off. Nothing describes a tap or a trigger, which is the single feature that makes a fixed volume of water last a whole wash.
No weight, no packed size, no heating figure. The bag is called light and quick to warm, and neither claim carries a number.
Before you hang it
This is not a water treatment device, and nothing here says anything about what may be put in it. Where you may use it is a matter for the site or the local authority rather than for the equipment.

What it does well, and where it gives way
Strengths
The simplest thing in this hub: no battery, no charging, nothing to fail except the hanging point
A hand-held head on a flexible hose is stated as supplied rather than sold as an upgrade
A carry handle is described, which on a bag that will be carried full is not a small detail
Compromises
No shut-off on the head, so the 20 litres runs until the bag is empty or the hose is kinked
No hose length, so nothing says how high the bag has to hang for the head to reach you
No packed weight, which is the figure that decides whether it travels with you or stays in the car

What people ask before buying
How long does 20 litres last?
The listing does not say, and without a flow rate or a shut-off there is nothing to work it out from. What can be said is that a full bag is heavy: water is about a kilogramme per litre, so whatever the bag itself weighs, the hanging point has to take 20 kg of water on top of it.
Does the sun heat it enough?
The maker states that the black bag uses solar energy to warm the water and needs no electricity, and publishes neither a temperature nor a heating time. Two other bags in this hub publish both. This one publishes neither, so there is no figure to plan an evening around.
Mains-heated electric shower · 15 litre collapsible tank · 220 V 2000 W heater · 42 °C in 15 minutes stated · warm up to 3 hours stated · 3 or 4 litres per minute · 1.8 m hose
The only shower in this hub that heats its own water — a 15 litre collapsible tank with a 220 V heater, which means mains power or a 2000 W inverter before anything happens.
Best for: A camper van or a caravan with an inverter or a hook-up, where hot water on demand is worth carrying a heater for.
Rechargeable pump unit, no tank · 3 or 4 litres per minute · 4800 mAh · IPX7 · shut-off valve on the head · built-in water filter · no run time, no hose length, no weight
A pump rather than a bag, carrying the highest ingress rating in this hub at IPX7 and a shut-off valve on the head — and publishing no run time at all.
Best for: A pitch or a van with a water container on site, where a shut-off on the head and a rating that survives immersion matter more than a published run time.
Hand-pumped pressure shower · 8 litres · built-in hand pump, no power source · neoprene insulation · polypropylene body · about 2.1 kg empty · no heating function
The only hand-pumped shower in this hub: an 8 litre pressure tank with no battery, no USB and — as the maker states outright — no heating of its own.
Best for: Van and campsite use where warm water is boiled or carried rather than heated on the spot, and where nothing should depend on a charge or on sunshine.
