Chargers, cables, power banks, cases and mounts from Choetech, Krome, Endefo and Hoco.
Most phones now ship without a charger, and this is the wrong place to save. A cheap adapter trickles, runs hot and shortens battery life; a reputable fast-charger at the right wattage does not. Match the wattage to your phone — paying for 65W when the handset accepts 25W buys nothing.
For cables, the connector standard matters more than the price. USB-C to USB-C with Power Delivery is what modern phones and laptops want; older Lightning and Micro-USB stock is worth checking before you buy in bulk.
Power banks are rated in mAh, but the useful number is how many full phone charges that gives you — roughly 10,000mAh for two.
