説明
A power bank only earns its place when it is the thing you did not have to think about. Forgetting a cable, forgetting to charge it, and discovering the battery is empty at the moment the phone dies are the three failures that make the object useless, and all three of them are design decisions rather than bad luck.
The Reserve 10 answers them in order. Cables are built into the body, so there is nothing to forget and nothing to lose at the bottom of a bag. A digital display reports the exact percentage rather than four ambiguous dots, which means you know whether you have a full charge for a flight or a partial one for a taxi. The cell holds 10,000 mAh, enough for two full charges of a modern phone with margin, and the output reaches 23 W, which is fast enough to matter on a device that supports quick charging.
Input runs on USB-C or Micro USB, so the bank charges from whatever cable the household already owns, and a small LED lamp on the body covers the one situation where a phone torch costs battery you cannot spare. The shell is a hard plastic case with rounded edges, sized to sit in a jacket pocket without a bulge that telegraphs itself.
It is a utilitarian object, and the design respects that. Nothing on it glows for decoration, nothing needs an app, and the display tells you the truth before you leave the house.
The best power bank is the one already in your bag with a cable attached to it.

Where It Earns Its Place
It belongs in the bag of someone who travels for work and has learned that airport charging points are a lottery. It suits a commuter whose phone is the ticket, the map and the payment method in one device. It makes sense for a photographer or site engineer carrying two devices that both need to survive a long day away from a socket, and it is the obvious answer for a household that keeps one charged bank by the door for power cuts. In each case the built-in cable is the feature that decides whether it gets used, because the bank you remembered to bring is the only one that helps.

Questions Buyers Actually Ask
Q: How many times can it charge a phone?
At 10,000 mAh it covers roughly two full charges of a current smartphone, allowing for conversion loss. A phone with a 4,500 mAh battery will see slightly more than two charges in practice.
Q: Are the cables really built in?
Yes. The output cables are part of the body, so nothing needs to be carried separately. Use the USB-C or Micro USB input port to recharge the bank itself.
Q: Does the display show exact charge?
It shows a digital percentage, which is far more useful than four indicator dots when you are deciding whether to leave the house.
Q: Is 23 W fast enough to quick charge?
It supports one-way quick charge and reaches 23 W, so a compatible phone will charge quickly. A laptop will not run from it, and a tablet will charge slowly.
Q: Can it charge two devices at once?
It can share output across connected devices, but the 23 W ceiling is divided between them. Charge one device at a time if speed matters.
Q: Is the LED lamp bright enough for a power cut?
It is a utility lamp, not a lantern. It is enough to find a fuse box or light a doorway, and it draws very little from the cell.
Q: Can I take it on a plane?
At 10,000 mAh it sits well inside the usual carry-on allowance. Keep it in cabin baggage, not checked luggage, as with every lithium bank.
Q: How long does it take to recharge?
It depends on the charger you use. A 20 W USB-C charger fills it far faster than an old 5 W phone adapter, so pair it with a modern plug for the best result.
