Enkola y'okutuma
Enkola y'okuddamuEky'okubonereza Ky'omulembe
Tusanyuse okukulaba ku Roymall, wobudde bwo obw'ebintu ebirungi ebikwata ku ggwe. Tukwagala nnyo okukulaba era tukwagala okukwebaza okukola naffe. Tugenda okukwebaza okukola naffe nga tukwongera ku kiseera ky'okwagala mu bigulo byo. Bw'ogula naffe, tojja kufuna ebintu ebirungi ebitonotono ebitambuza obulamu bwo, naye ojja kufuna n'eky'okubonereza ky'omulembe ku buli kugula kwo. Otegefu okunoonya ebintu ebirungi ebitonotono ebigula? Noonya ebintu byaffe ebirungi, gula, era otungule okufuna eky'okubonereza ky'omulembe ne kugula kwo.Enkola Y'okutuma
Tujja kukola bulungi okutuma ebintu byo oluvannyuma lw'okugula era tujja kukakasa nti bijja kufika bulungi. Ebikwata ku kutuma bijja kufunibwa mu email yo ey'okukakasa.Mu ngeri yonna, ebintu bijja kutandikibwa okutumibwa mu nnaku 2.Mu kiseera ky'obuzibu, bijja kulemererwa nga bino: Bw'ogula ku Lw'okuna, Sabbiiti oba ennaku z'amawanga, bijja kulemererwa ennaku 2..Mu ngeri yonna, bijja kusasulwa mu nnaku 5-7 ez'okukola (Ku Lw'okubiri okutuuka ku Lw'okuna) nga tebirina kulemererwa ku nnyonyi oba ebirala ebitakozesebwa..Olw'okuba enkola yaffe y'okutuma eri mu nsi yonna, ekiseera ky'okutuma kijja kuteekwa okuba ku nsi gy'oli, kale kijja kutwala ekiseera era tusaba okumanya nti ojja kutunga nga oli mu nsi endala oba mu nsi endala.1. Enkola Y'okuddamu N'okukyusa
Tujja kukkiriza ebintu ebiguliddwa ku roymall.com. Bw'ogula ku badduukizi baffe oba ku badduukizi endala, tojja kusobola kuddamu ebintu ku ffe. Ebintu ebiguliddwa oba eby'okubonereza by'omulembe tebijja kukkirizibwa okuddamu. Okuddamu ekintu, kijja kuba tekikyali kukozesebwa era kijja kuba mu kifo ekimu nga bwekyafunibwa. Kijja kuba mu kifukiriro eky'obulungi.Oluvannyuma lw'okufuna ebyokulabirako okuva ku ffe, tusaba okukifukirira ebintu byo ebiddayo era otume ku posita oba ku mutume endala.Tujja kukola ebintu byo ebiddayo oba eby'okukyusibwa mu nnaku 3-5 ez'okukola, oluvannyuma lw'okubifuna. Ssente zijja kuddamu mu ngeri ey'obulungi ku ngeri yo ey'okusasula.Tebijja kukkirizibwa okuddamu oba okukyusibwa ebintu ebikozesebwa ku ggwe, okuli obunene obukwata ku ggwe, langi ekwata ku ggwe, oba ebifaananyi ebikwata ku ggwe.Oli mukozi, tusaba okutukwatako. service@roymall.com oba Whatsapp: +8619359849471
2.Enkola Y'okuddamu Ssente
Ojja kufuna ssente zo zonna oba 100% ku ssente zo mu dduuka oluvannyuma lw'okufuna eky'okuddamu era okukikakasa. Ssente zijja kuddamu mu ngeri ey'obulungi ku ngeri yo ey'okusasula. Tusaba okumanya nti ssente z'okutuma n'ebirala tebijja kuddamu. Ssente z'okutuma ez'enjawulo tezijja kuddamu, oluvannyuma lw'okutuma. Ojja kuba osobola okuzisasula era tetujja kusobola kuzikyusa oba kuziddayo, wadde nga ebintu byo bijja kuddayo ku ffe.Oluvannyuma lw'okufuna era okukakasa eky'okuddamu, tujja kukutumira email okukulaga nti twafuna eky'okuddamu. Tujja kukulaga nti eky'okuddamu kyakirizibwa oba ky'okuddamu kyakakanirwa.Bw'olina ebizibu ku ngeri y'okuddamu ssente, tusaba okutukwatako. service@roymall.com oba Whatsapp: +8619359849471
Features:
- Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging).
- Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%). Particularly suitable for LED.
- High output current, the max output current can reach 8A.
- Four high frequency capacitance, can lower output ripple, enhance the work stabilization.
- Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good,and wonu2019t affect each other.
- Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
- 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability.
- Double color lamp, working condition be clear at a glance
- Voltage and current are adjustable,wich effect is good.
